Q [June, Head darker aud more distinctly punctured than the rest of the upper-surface, with the line separating the clyjieus from the front very distinct. Thorax of a chestnut colour, shining, rather finely and evenly punctured, the punctures, however, rather coarser, and more numerous at the sides and front angles than elsewhere ; it is about oue-third broader than long. Scutellum distinctly punctured, but with the sides and apex smooth. Elytra obsoletely punctured, the punctuation near the ecutellum more distinct than elsewhere. Pygidium closely punctured, and furnished with fine hairs. Under surface with a thick woolly pubescence, except on the middle of the abdomen, where there is only a scanty pubescence. Legs pitchy, hinder tibise moderately dilated at the extremity. I have seen only a single specimen of this insect, which cornea from North-West Australia ; its rough pygidium readily distinguishes it from the other species. Thornhill, Dumfries : 26th March, 1874. DESCEIPTIONS OF FIVE NEW LUCANOID COLEOPTERA. BY CHAS. O. WATEEnOTJSE. 1. Pbismognathus {Oyclorasis) angulaeis, sp, n. ? . Niger, nitidus, Capite pone oculos vix angustiore. Thorace sat crcTjre fortiter punctato, angtiUs antlcis pr'ominentihus. Elgtris crehre sat fortiter irregulariter punctatis, laterihus siihtilius obsolete punctulatis. Long. 9 lin. Closely allied to P. platycephalus, the head is, however, somewhat narrower ; the neck being as it were swollen, the cj-cs are much less prominent than in that species, and the punctuation throughout is more distinct. The thorax is narrower, the anterior angles are very prominent, and the sides in front are less oblique ; the punctuation is moderately close and strong. The elytra present some indications of longitudinal impressed Unes ; the punctuation is moderately strong and close, and somewhat irregular, considerably less close and distinct than in P.platycephalus, and the sides are slightly opaque, obscurely aud very finely punctured.
