with fine white hairs, the first third of their length fulvous, a spot at the shoulder and the rest of the 

 surface black ; pygidium with an elongate central line devoid of hairs. t

This species represents M. dimidiata in miniature, but is at once distinguished 

 from it and from M. notabilis by its much smaller size, its short antennae, and the 

 elongate nude space of the pygidium, which in M. notabilis is represented by a conical 

 protuberance. The antennas in the present species do not extend much further than to 

 the commencement of the thorax. The female has the usual round fovea on the last 

 segment, but does not differ in other respects. 



6. Megalostomis flavipennis. (Tab. n. fig. 13.) 



2 ■ Elongate, subcylindric, black ; thorax minutely, elytra more deeply punctured, finely pubescent, flavous- 

 testaceous. 



Length 5 lines. 



Lower part of the head rugose-punctate, with a very distinct longitudinal median ridge, extending from the 

 upper margin of the eyes to the clypeus ; a smaller ridge runs parallel with the inner orbit of the eyes ; 

 vertex more distantly but deeply punctate ; antennae black, reaching to the base of the thorax, the latter 

 with the posterior margin straight at each side, broadly lobed in the middle, the lateral margins very 

 slightly rounded ; surface with an obsolete oblique depression from the anterior angles towards the middle 

 of the disk, distinctly covered with whitish hairs at the sides ; the disk itself rather closely and finely 

 punctured ; scutellum also finely punctate and pubescent ; elytra convex, a little narrowed towards the 

 apex, irregularly and more strongly punctured than the thorax, and sparingly covered with yellowish 

 hairs ; underside and legs black, covered with fine pubescence. 



Hab. Nicakagua, Chontales (Belt). 



A single female was obtained by Mr. Belt in Nicaragua ; it differs from its allies 

 in the uniform light yellow colour of the elytra.

Of the nineteen known species of this genus, four have been found in Central 

 America. From Coscinoptera, which they closely resemble in form, they are principally
