the long acnte subapical tooth on the anterior pair reaching to near the tip of the 
inwardly directed uncus. The mesosternum is protuberant, as in P. leucothyrea. 
4, Promecops leucothyrea. (Tab. XIV. figg. 23, ¢ ; 24, 2, var.) 
Promecops leucothyreus, Fahy. in Schénh. Gen. Cure. vi. 1, p. 328°. 
Promecops quadrimaculatus, Jekel, in Mus_ Brit.’. 
Oblong, robust, piceous; variegated with a dense clothing of cinereous, brown, and blackish scales, the 
last-named usually clustered into two broad vittz on the dise of the prothorax (sometimes more 
extended and coalescent, leaving only a basally abbreviated median line and two short streaks on each 
side cinereous), the cinereous scales on the elytra condensed into an interrupted oblique or transverse 
fascia before the middle and another near the apex; the scales at the apex of the rostrum, on the 
scutellum, humeri, elytral fascize, base of the femora, and tarsi often more or less green, those on 
the under surface varying in colour from cinereous to green; the upper surface also set with very 
short, scattered, curled, decumbent sete. Head and rostrum densely punctate, the vertex with a 
transverse raised line separating the exposed portion from that covered by the prothorax, the rostrum 
moderately broad, canaliculate; eyes strongly transverse, narrow; joint 2 of the funiculus slightly 
shorter than 1. Prothorax transverse, convex, obsoletely canaliculate, rounded at the sides, the latter 
parallel at the base; with coarse punctures intermixed with a dense fine punctuation. Elytra 
subparallel in their basal half, rather convex, punctate-striate, the interstices feebly convex. Meso- 
sternum protuberant. Legs stout; all the tibiew strongly unguiculate in g, more feebly so in Q ; 
tarsal claws long, free. 
Length 43-6, breadth 2-22 millim. (¢ ?.)

I have seen seventeen specimens of this species, including the type and two others 
from Colombia in the British Museum. It is extremely variable in regard to the 
markings of the upper surface, according to the predominance of the dark or light 
scales, and the elytral fasciz are often broken up into spots, which are sometimes 
green. The Tampico example is like the type. TheSalina Cruz specimen (9) 
(fig. 24) and one of those from Colombia are cinereous variegated with fuscous. 
The Mexican male figured (fig. 23) has been lent me by Signor A. Solari. 
5. Promecops dentimanus, sp. n. (Tab. XIV. figg. 25, 25a, ¢.) 
Oblong, robust, piceous; variegated with a dense clothing of brown, blackish, and cincreous scales, the 
blackish scales on the prothorax clustered into a curved line on each side of the disc and those on 
the elytra into a common, broad, irregular, post-median fascia, which extends up the suture to the base 
and is limited anteriorly by a transverse row of confluent cinereous spots ; the elytra also set with long, 
scattered, suberect sete along each interstice, the rest of the surface with short, curled, decumbent, 
bristly hairs. Rostrum broad, somewhat concave, canaliculate, densely punctate; eyes strongly 
transverse, narrow ; antenne comparatively short, the scape much widened towards the tip, joint 2 of 
the funiculus shorter than 1, 5-7 transverse. Prothorax transverse, obliquely narrowed towards the 
base and apex, as wide in front as behind, finely punctate, carinate or obsoletely canaliculate down the 
middle from near the apex to the base. Elytra oblong-subtriangular, punctate-striate, the interstices 
feebly convex. Mesosternum not protuberant.. Legs stout; all the tibie strongly unguiculate in both 
sexes, the intermediate pair hollowed near the apex within in g, more feebly so in Q ; anterior
