Evparia castanEA. (Pl. XVII. fig. 3.) 
Tuts insect has hitherto been known only by the short description 
given in the Encyclopédie Méthodique (vol. x. p. 357), by Messrs. 
Serville and St. Fargeau, who merely state that “ce nouveau genre, 
trés voisin de celui d’A4phodie, s’en distingue par les caractéres 
suivans: cdtés de la téte dilatés, et formant un triangle, angles 
postérieures du corselet fortement échancrés, angles huméraux 
des élytres pointus, et trés prolongés en devant; giving the fol- 
lowing short specific description : 
“ Euparia fuscé castanea ; punctata; capitis angulis lateralibus 
dilatato-subspinosis ; thoracis basi sinuata, utrinque margi- 
nata; elytris striato-punctatis, humeris porrecto-subspinosis.

“ Patrie inconnue.” 
Dejean introduced this insect into his ‘‘ Catalogue des Coléop- 
téres” 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 23 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 setze. 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), maxillee (fig. 36), and lower 
parts of the mouth (fig. 3c), as may be expected, scarcely differ 
from those of Aphodius (Mod. 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 strize, each of which 
is margined with a row of small punctures on either side. The 
fore tibize are tridentate, and the hind ones simple and slender.
