212 HETEROMERA. 
Compared with typical specimens the three individuals from Guatemala have the 
thorax more shining; the two (male) examples, from British Honduras, are much 
narrower, and with the thorax slightly rounded at the sides; both, however, merely 
represent varieties of one and the same species. 
Specimens of this species in the Sallé collection are labelled Apsida pulchra, Chevr. 
A female example from Chontales is figured. 
2. Hapsida gibbosa. 
Form of H. chrysomelina; black, the upper surface unicolorous dark bronze, slightly shining. Head very 
minutely and sparingly punctured; prothorax transverse, the sides and the very prominent anterior 
angles strongly margined, the apex very deeply arcuate emarginate, the surface almost smooth; elytra 
strongly convex, almost gibbous in the middle, the disc broadly flattened behind, with regular rows 
of fine punctures (much more distinct towards the suture, and the punctures distant one from another), 
the interstices almost smooth, the surface, if anything, a little brighter in tint than the prothorax, and 
sometimes slightly cupreous; beneath shining black, almost smooth ; metasternum broadly and transversely 
deflexed behind. 
Length 7-113 millim. (¢ 2.) 
Hab. Mexico, Jalapa (Hoge); Brirtisa Honpuras, Belize (Blancaneaus) ; GUATEMALA, 
San Juan in Vera Paz, Chacoj, San Gerénimo, Zapote, Volcan de Atitlan, Mirandilla, 
Cerro Zunil, San Isidro, El Tumbador, Las Mercedes (Champion). 
An abundant species in the forest-region of Guatemala, and found in shady places in 
the curled-up withered leaves of recently fallen trees; one example only from Mexico. 
This insect so closely resembles H. chrysomelina, except in its unicolorous dark 
bronzy upper surface, as to be scarcely distinguished from that species; I am unwilling, 
however, to treat it as a variety, more especially as in the very large number of speci- 
mens (about 150) before me I can find no intermediate forms. Nevertheless, like 
H. chrysomelina, it varies very much in size and general shape, some examples being 
very much narrower than others. 
8. Hapsida seriato-punctata. (Tab. IX. fig. 25, ¢ .) 
Form of H. chrysomelina; unicolorous blackish bronze, with a slight cupreous tinge, shining. Head with a 
few widely scattered minute punctures; prothorax as in H. chrysomelina; elytra with regular rows of 
coarse deep punctures (rather finer and placed a little closer together towards the suture), the interstices 
exceedingly minutely and very sparingly punctured; beneath black, the epipleure slightly cupreous, 
shining, almost smooth. 
Length 103 millim. ( 2.) 
Hab. Mexico, San Andres Tuxtla (Sallé). 
One example. This species is allied to H. chrysomelina and H. gibbosa, but will at 
once be known by the regular rows of coarse impressions (continued to the sides and 
apex) on the elytra; the upper surface blackish bronze and shining; and the elytra less 
gibbous in the middle. HH. seriato-punctata resembles a species of Chrysomela, e. g. 
C. lamina, of Europe.
