AUSTRALIAN LAEVAL CABABIDAE OF THE SUBFAMILIES HARPALINAE, LICINHSTAE, ODACANTHINAE AND PENTAGONICINAE (COLEOPTEBA) B. P. Moore C.S.I.B.O., Canberra [Read 30th June, 1965] Synopsis Larvae of the following Carabidae are described and figured for the first time : Cenogmus castelnaui Csiki (Harpalinae) ; Lestignathus cursor Erichs. and Dicrochile brevicollis Chaud. (both Licininae) ; Eudalia macleayi Bates (Odacanthinae) ; and Scopodes simplex Blackb. (Pentagonicinae). The subfamily Pentagonicinae and all five of the genera were previously unknown in the larval state. This is the second of a projected series of papers (for the first, see Moore (1964)) dealing with Australian carabid larvae, a group about which singularly-little information has ever appeared in print. The ultimate aim of the series, namely, the recognition and description of all the principal genera, is likely to prove a long-term project, in view of the size of the fauna and of the difficulties associated with the collection of adequate larval material in an essentially arid environment. However, the piecemeal description of isolated genera, as they become available, serves the very important immediate purpose of adding to our knowledge of world carabid larvae as a whole, and so providing a better perspective for developing the general classification admirably pioneered by van Emden (1942). Thus, on the basis of even the present very limited material, it has been possible to add three subfamilies and nine genera to the tally of those already positively identified in the larval stage. Addition of the few important subfamilies remaining as yet unknown (some of which will undoubtedly fall to the lot of Australian coleopterists) would place the taxonomy of larval Carabidae on a sound basis and allow it to play its full part in the understanding of carabid evolution as a whole. Subfamily Harpalinae Cenogmus castelnaui Csiki (rotundicollis Cast.) (Figs 1-2) Mostly pale, whitish ; head light brown, the tips of the mandibles darker-Head rather large, very transverse, moderately sclerotized ; frontal piece triangular, almost reaching hind-margin ; epicranial suture very short ; ventral suture obliterated anteriorly ; nasale truncate, not prominent, lightly cuspidate ; neck weak but with strong cervical keels ; ocelli present, six on each side ; postocular furrows feeble ; mandible short and stout, with a basal penicillus ; retinaculum small ; antenna slender, shorter than the mandible, four-segmented ; maxilla setose ; inner lobe present as a stout tubercle, fused with the stipes, unisetose before apex ; maxillary palp three-segmented, the palpiger distinct ; labium quadrate, palp two-segmented ; ligula small, bisetose, the setae situated on small tubercles. Pronotum slightly transverse, lightly sclerotized, slightly broader than head ; legs short and stout, with two subequal terminal claws. Abdomen with tergites lightly sclerotized, unmargined at sides ; pleurites and ventrites membranous ; cerci fixed, very short, unsegmented but with setiferous nodes ; pygopodium stout, slightly shorter than the cerci.
