Mr. J. O. Westwood's Descriptions, ^c. 239 XXXVII. Descriptions of some Exotic InsectSy belonging to the Family Aphodiidse. By J. O. Westwood, F.L.S. [Read 7th August, 1843, and 7th April, 1845.] EUPARIA CASTANEA. (PI. XVII. fig. 3.) This insect has hitherto been known only by the short description given in the Encyclopedie Methodique (vol. x. p. 357), by Messrs. Serville and St. Fargeau, who merely state that "^ce nouveau genre, tres voisin de celui d'/ijjJiodie, s'en distingue par les caracteres suivans : cotes de la tete dilates, et formant un triangle, angles posterieures du corselet fortement echancres, angles humeraux des elytres pointus, et tres prolonges en devant; " giving the fol-lowing short specific description : " Euparia fusee castanea ; punctata ; capitis angulis lateralibus dilatato-subspinosis ; thoracis basi sinuata, utrinque margi-nata ; elytris striato-punctatis, humeris porrecto-subspinosis. " Long. 3 lin. " Patrie inconnue." Dejean introduced this insect into his " Catalogue des Coleop-t^res" as a native of North America ; a specimen of the same insect, sent by M. Gory to Mr. Hope for examination, was also labelled North America. This specimen was 2 J lines long (English measure), of a dark castaneous colour, with the elytra somewhat darker, the pronotum very glossy, and the sides of the body clothed with short pale luteous setcB. The head is nearly as broad as the prothorax, with a deep incision on each side, leaving the lateral angles free and prominent. The mandibles (fig. 3a), maxillae (fig. 36), and lower parts of the mouth (fig. 3c), as may be expected, scarcely differ from those o? Aphoclius (Jsiod. Class. Ins. i. 201, cut 20, fig. 15 — 18); the mentum is however more quadrate, and broader in front (fig. 3c), and I did not perceive the basal joint of the labial palpi, which was probably retracted. The prothorax is broad, and has the fore angles porrected, whilst the hind ones are emarginate. Each elytron has eight fine simple longitudinal striae, each of which is margined with a row of small punctures on either side. The fore tibiae are tridentate, and the hind ones simple and slender.
