GONICGLUS. 613 
19. Gonicelus championi, sp. n. 
Anguste ovalis, parum covexus, piceus, pube elongata erecta vestitus ; antennis pedibusque rufis; prothorace 
elytris fere angustiore, dorso irregulariter fortiter punctato; elytris seriebus internis punctorum minus 
obsoletis. 
Long. 5 millim. 
Hab. Guatemata, Capetillo (Champion). 
We have received only one example of this species. It is a male, and differs from 
(7. hystrix in having a fine pliciform tubercle on the middle of the head near the front, 
and two extremely minute angular projections on the middle of the front margin of the 
thorax ; the emargination of the front tibia is more definite and the larger punctures 
on the metasternum are much less conspicuous. 
Group 3.—Small insects, never attaining 5 millim. in length, rarely 34 or 4; the head 
of the male sometimes armed, but the front tibiae never emarginate. The anterior 
marginal line of the thorax usually less distinct than it is in the first two groups. 
—Species 20-38. 
20. Gonicelus throscoides, sp. n. 
Ovalis, posterius attenuatus, convexus, niger, antennis pedibusque rufis, pube flavescente depressa vestitus; 
prothorace elytrisque subtilius punctatis. 
Long. 32 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Head very little punctate. Thorax accurately adapted to the elytra, much narrowed 
in front; marginal line definite and very distinct in its deflected sides; the coarse 
lateral punctuation much finer than in the species of Group 2; the hind angles are 
a little acute; the basal margin is very fine and indistinct. ‘The series of punctures on 
the elytra are unusually fine, and the dense fine pubescence is more depressed than 
usual. The flanks of the prothorax are very densely, but finely sculptured. The 
pubescence of the under surface is extremely fine and minute. ‘The metasternum is 
almost destitute of a channel. One specimen. 
Although this insect has no striking peculiarities it does not appear to be closely 
allied to any except the following species. ‘The definite anterior marginal line of the 
thorax and the somewhat larger size suggest that G. throscoides may prove, when the 
male is known, to come near some of the species placed at the head of the genus; but 
I think it more probable that it is really allied to G. sudtilis. It is distinguished from 
that species by the complete absence of a depression extending laterally from the angles 
of the scutellum.
