216 HETEROMERA. 
genus, varies considerably in general shape. Fully coloured examples have the upper 
surface reddish testaceous; the suture, two dorsal stripes (sometimes connected before 
the apex), and the lateral margin, black. er 
We figure a male of the striped form (fig. 28) from Volcan de Chiriqui, and a female 
of the pale variety (fig. 27) from Cordova; also (fig. 28a) the whole of the cedeagus 
of the male. 
GONOSPA. 
Gonospa, F. Bates in litt. 
Mentum trapeziform, the sides strongly deflexed; last joint of the maxillary palpi broad and swollen, sub- 
securiform, the apex slightly concave; antennz short, not reaching the base of the prothorax, the six 
outer joints flattened and broader and widening outwardly, joints 6-10 transverse and subserrate within, 
the eleventh joint twice the length of but slightly narrower than the tenth, and broadly rounded at the 
apex; head slightly deflexed, short, broad; epistoma broadly truncate in front; labrum partly hidden 
from above, without visible connecting clypeus; eyes convex, widely separated, rounded, very slightly 
emarginate in front, and free of the anterior margin of the prothorax; prothorax strongly transverse, the 
lateral margins swollen and reflexed, the base strongly bisinuate, with a shallow oblique fovea on each 
side, and closely embracing the elytra; scutellum small, triangular; elytra slightly wider than the pro- 
thorax at the base, short, convex, shallowly punctate-striate, and with a marginal row of irregular 
impressions ; legs short; tibiz slightly curved, the spurs small; tarsi short, the first joint of the posterior 
pair short, the length of the two following joints united ; prosternum broad, horizontal, the apex rounded, 
slightly produced, and margined within in G. phedonoides, still broader and triangularly produced in 
G. amazonica and G. brasiliensis; mesosternum broad, the apex slightly produced and semicircularly 
emarginate in G. phadonoides, V-shaped and deeply excavate within in G. amazonica and G. brasiliensis ; 
intercoxal process very broad, subtriangular; trochantin distinct; epipleure abruptly ending at the last 
ventral suture ; form short oval, convex; surface shining, metallic. 
This new genus, already recognized by F. Bates, contains three species, one from the 
State of Panama, the other two from the Amazons*. From Hapsida, with which it 
* Gonospa amazonica. 
Bronze-black, shining; head coarsely and rather closely punctured, the epistoma defined posteriorly by a 
deeply impressed groove; prothorax moderately transverse, the apex rather deeply emarginate, the 
anterior angles prominent, the surface rather coarsely but not closely punctured; elytra with regular 
rows of coarse shallow punctures, and a marginal row of coarse irregular impressions, the interstices 
exceedingly finely and sparingly punctured, the sides broadly and indefinably dark reddish brown: 
beneath shining, finely and sparingly punctured, the prosternum, the metasternum in front, and the 
anterior margin of the first three ventral segments with coarser impressions. Length 4 millim. 
Hab. Amazons, Santarem (H. W. Bates). 
A single example in Mr. F. Bates’s collection, labelled as above. Allied to but distinct from G. phadonoides ; 
differing in the structure of the pro- and mesosternum, the sculpture of the upper surface, &c. 
Gonospa brasiliensis. 
Closely resembling G'. wmazonica, and differing as follows :—Larger, colour dark bronze; prothorax less 
regularly punctured, the disc and sides with coarser impressions, the anterior angles more obtuse and 
rounded ; elytra unicolorous bronze, the interstices still more finely punctured, the impressions along the 
margin shallower and not so regularly placed; the ventral surface more regularly punctured and without 
coarser impressions along the anterior margin of the first three segments; the rest as in G. amazonica. 
Length 63 millim.
