EHTNCHOPHOEA. 





Prothorax a little longer than broad, Insinuate at the base, narrowing from the middle, punctured along 

 the sides, base, and apex, almost smooth on the disc. Scutellum elongate-triangular, hollowed anteriorly. 

 Elytra wider than the prothorax, somewhat rapidly narrowing from the rounded humeri, depressed at 

 the sides below them and also on the disc towards the apex; rather coarsely punetate-striate, the 

 interstices minutely punctured down the middle. Pygidium flattened, sparsely, coarsely punctate, 

 fulvo- cristate along the apical half. Beneath somewhat closely punctured, the flattened portion of the 

 metasternum and first ventral segment almost smooth. Femora with a few very short hairs beneath. 

 Tibiae finely ciliate within. 

 Length 21, breadth 7| millim. ( 5 .) 



Hab. Costa Rica, Azahar de Cartago ( Underwood).

17. Metamasius nudiventris, sp. n. (Tab. V. figg. 24, 24 a, 2 .) 



Elongate-oval, rather convex, opaque above; black, the elytra each with a curved, oblique, transverse fascia 

 at about one-third from the base and an irregular, transverse, subtriangular or T-shaped mark on the 

 disc beyond the middle (neither reaching the suture), a minute spot on the shoulder beneath, and 

 sometimes one or two others along the basal margin, rufous. Rostrum nearly as long as the prothorax, 

 moderately stout, curved, subcylindrical, shining, sparsely punctate in the <$ , almost smooth in the $ , the 

 widened basal portion faintly canaliculate, the frontal fovea small. Prothorax about as long as broad, 

 parallel at the sides posteriorly, feebly bisinuate at the base, very sparsely, finely punctate, flattened on 

 the disc behind. Scutellum elongate-triangular. Elytra oblong-subcordate, much wider than the 

 prothorax, finely puitctate-striate. Pygidium coarsely punctured. Beneath very sparsely punctate. 

 Femora with a few very short hairs beneath. Tibiae finely ciliate. 



d . Ventral excavation long and shallow, the fifth segment with a few short scattered hairs at the tip, as in 

 the 5 ; posterior tibiae fringed with moderately long hairs. 



Length 10|-13, breadth 3 T %-5 millim. ( tf $ .) 



% Hab. Nicaragua (Salle\ Chontales (Belt). 



Two males and five females. Extremely like the dark form of M. ensirostris (Germ.) 

 dispar^ Gyll.), but easily separable therefrom by the absence of the dense cluster 



hairs on the last ventral segment in the male, and by the non-pilose pro- 

 sternum, &c, in this sex ; the female, too, is wifhout the two tufts of hair at the tip 

 of the abdomen. M. bisbisignatus (Gyll.) has a longer and flatter prothorax, with an 

 elongate punctured area on the disc at the base, and the male-characters as in 

 Jf. ensirostris. In the present species the tibiae are finely ciliate in both sexes.

18. Metamasius scutatus, sp. n. (Tab. V. figg. 25, 25 a, 6 .) 



Oblong- elliptic, rather broad, opaque above, shining beneath; black, the prothorax with two broad, 

 posteriorly bifurcate, ferruginous vittse on the disc (leaving a lanciform median stripe, a curved streak on 

 each side of it on tho basal half, and the margins, black) ; the elytra ferruginous, each with five black 

 spots arranged in two oblique rows across the disc (one below the shoulder, transverse, one near the
