26 OrpER—COLEOPTERA. Srection—PENTAMERA. 
Genus 13—CALLYNOMES. Westw. 
Corpus oblongum subdepressum ; prothorace subrotundato. Caput convexum, margine antico lato rotundato 
parum reflexo. Antenne articulo primo maximo, cavitatem inter mentum et oculos exacte claudens; secundo in 
medio disci inferi precedentis inserto. Maxille valid, galea curvata falciformi acutissima ; mandone in dentem 
breviorem compressum apice acuto oblique truncato. Mentum maximum planum, capitis partem anticam 
inferam tegens, antice paullo latius, basi in dentem dependentem producta ; palpis labialibus gracilibus, mento 
absconditis. Prosternum in dentem parvum porrectum productum. Prothorax subrotundatus elytris angustior. 
Pedes satis graciles, tibiis anticis maris simplicibus edentatis, feemine (pl. VII, fig. 7 e) extus bidentatis dente 
infero parvo; tibiis 4 posticis extus dente medio in femina tantum armatis. Tarsi omnes in utroque sexu 
4-articulati, unguibus minutis armati. Abdomen segmentis basalibus in medio parum depressis. 
The extraordinary size of the first joint of the antenne, the very large mentum, and the 4-jointed tarsi 
in all the feet of both sexes, will at once distinguish the species of this genus, which is essentially Oriental.

I suppose the two specimens of this curious species which I have seen are males, because the second and 
third segments of the abdomen are slightly longitudinally depressed on their ventral surface. They have, 
however, the tarsi 4-jointed with very small ungues, The maxille have the outer lobe forming a slender very 
aeute curved hook, and the inner lobe is obliquely truncate and sharp (fig. 62). The mentum is somewhat hexagonal, 
being widest at the anterior lateral angles: it covers the whole of the front of the under side of the head. Its 
inside is represented in fig. 6, shewing the small size of the labial palpi, the labium itself forming two setose 
diverging lobes, lying flat on the inner surface of the mentum, arising slightly below its centre. The prosternal 
point is porrected in front of the anterior coxee. The basal joint of the antenne is very large, flat, and sub- 
triangular, with the anterior angles rounded, it exactly closes the space between the eyes and the mentum, 
forming a continuous flat surface with the latter.
