COSMONOTA.—HAPSIDA. 211 
impressions on each side before the prominent lateral margins ; scutellum large, triangular, reddish brown; 
elytra distinctly wider than the prothorax at the base, slightly rounded at the sides (but not in a line 
with the prothorax), widest about the middle, strongly margined, the humeri prominent and slightly 
grooved within (for the reception of the posterior angles of the prothorax), regularly punctate-striate (the 
punctures not very closely placed, and rather coarse), the interstices flat, and finely and sparingly punc- 
tured, red, the lateral margins narrowly (and the epipleurse) black ; legs long, piceous, clothed with short 
scattered hairs, the knees red, the apices of the anterior tibie, and the stout tarsi beneath, somewhat 
thickly clothed with fulvous hairs ; epipleure broad, extending to the apex of the elytra; beneath dark 
reddish brown, shining, sparingly punctured, each puncture bearing a short fulvous hair. 
Length 10 millim. 
Hab. Nicaragua, Chontales (coll. F. Bates, Belt). 
Three examples. This distinct species was discovered by the late Mr. Belt. C 
pubescens is allied to an undescribed insect from the Amazons, and with it will probably 
have eventually to be separated from Cosmonota. The long legs and antenne, and 
pubescent under surface and legs, are characters not to be found in the other species 
of this genus; the head, also, is somewhat differently formed. 
HAPSIDA. 
Apsida, Lacordaire, Gen. Col. v. p. 309, nota; F. Bates, Ent. Monthly Mag. x. p. 15 (1873). 
Hapsida, Gemm. & Harold, Cat. vii. p. 1955. 
This Neotropical genus, briefly characterized by Lacordaire, has been fully described 
by Mr. F. Bates; five species are known, all of which are found in our country, whence 
we now add four others. Hapsida has its headquarters in Central America, the genus 
ranging from Mexico to Colombia. The different species are usually very common 
where they occur; they have quite different habits to those of most of the preceding 
genera of this group, and are found in or near the forest, upon herbage, or by beating 
the withered still-attached leaves of fallen trees in new clearings; never, so far as my 
experience goes, about fungi. The genus may be known among its allies by the five- 
jointed club of the antennz ; some of the species are beautifully ornamented with bright 
metallic green and cupreous stripes. All the species vary a good deal in size, general 
outline, and colour; one new one (f7/. terebrans) is remarkable for the structure of 
the secondary sexual organs of the male, which differ greatly from those of the allied 
species. The tarsi are slightly dilated in the males of the larger species, similar in 
both sexes in the smaller forms. The great resemblance of some of the species to 
the Chrysomelide is not to be overlooked. These insects, owing to their tough 
elytra and soft integuments, are difficult to pin without injury.
