The type of this insect was obtained by us from the Sallé collection. It is 
easily separable from the other Central-American species of the genus by the acute 
anterior angles of the pronotum, and by the series of well-defined ochreous spots 
along the costal margin of the corium; the ochreous lateral spots on the pronotum 
are small, triangular in shape, and placed a little behind the anterior angles. The face 
is sometimes obsoletely carinate between the eyes. The rostrum is black at the base. 
The four specimens seen from Mexico are all females, measuring from 5-6 millim. in 
length and 3-34 millim. in width. The Grenada examples in the British Museum 
have a ferruginous patch on each side of the pronotum behind the ochreous spot. 
A specimen from Vera Cruz is figured. 
2. Pelogonus eneifrons, n. sp. (Tab. XX. figg. 12,2; 13, 18a, ¢.) 
Pelogonus marginatus, Uhler, P. Z. S. 1898, p. 706; 1894, p. 222° (nec Latr.) (part.). 
. Broad ovate, black; the head from the ocelli forwards more or less shining and eeneous in colour, the rest of the 
surface opaque; the pronotum with the sides rather broadly, except at the lateral angles, and the basal 
margin in the middle, the corium usually with from two to four small spots on the outer margin, as well as 
the outer edge, and often a spot near the inner apical angle, and some marks on the pleura, ochreous; the 
head, pronotum, and scutellum with the usual irregular bluish-grey markings; the rostrum broadly black 
at the base, for the rest ochreous; the legs ochreous, in some specimens slightly infuscate; the upper 
surface with very minute scattered golden scales, the under surface with a bluish-grey pruinosity, the 
abdomen with bluish-white pubescence. Face densely rugulose, not carinate between the eyes, the latter 
moderately large. Pronotum, scutellum, and elytra sparsely, indistinctly punctate; pronotum about 
one-half wider at the base than at the apex, the sides slightly arcuate, the anterior and lateral angles 
rounded, the latter not projecting beyond the elytra; elytra somewhat rounded at the sides ; nervures 
_ of the membrane indistinct. 
Length 33-5, breadth 2-23 millim. (¢ ?.)

Apparently a common species in Central America, whence we possess twenty-four 
specimens. Itis very variable in size and colour, some specimens having the disc of the
