The genus Hemiopsida was proposed by Macleay for a 

 species, master si, which I have already recorded as a probable 

 synonym of Lycaon novus. The genus itself was referred to 

 the Elateridae, following Dicteniophort/s, but without its 

 affinities being noted. Previously the genus had been named 

 Lycaon by Bonvouloir, but that name having been already in 

 use, Blackburn (overlooking my previous note) proposed for 

 it the name Neolycaon . In the genus the antennae of the 

 male are considerably longer than those of the female, and 

 the eleventh joint is conspicuously longer. 



Hemiopsida concolor, Lea (Lycaon). 



This species was doubtfully referred to Lycaon, with the 

 general outlines of which it is certainly in close agreement, 

 but the sides of the prosternum are shallowly grooved (dis- 

 tinctly in front) for the partial reception (up to about the 

 ninth joint) of the antennae, the grooves, however, are not 

 of the deep nature and closed posteriorly as those of Fornax 

 and other genera, and are not margined within, although the 

 lateral margin bounding each is carinated. Probably a new 

 genus will be eventually required for it, but the type (and 

 only specimen I have seen) having lost the tips of both 

 antennae and all the claw joints, it appears desir.able not to 

 propose such a genus at present. 



Hemiopsida kraatzi, Bonv. (Lycaon). 



Specimens of this species are readily distinguished from 

 those of nova and nigricans (some specimens of which they 

 closely resemble) by the very short second and third joints 

 of antennae, the combined length of these being less than that 

 of the first or fourth. The antennae usually have the basal 

 joint blackish, but occasionally they are entirely pale ; the 

 abdomen is sometimes of a rather, bright red, but is usually 

 no paler than the rest of the under-surface. One male is 

 entirely of a dingy-red, except for a narrow blackish border, 

 where the prothorax, scutellum, and elytra meet. Two 

 females evidently belong to the species, but they differ from 

 the males in being longer and wider, elytra less narrowed 

 posteriorly, antennae considerably shorter, the three apical 

 joints much shorter and less cylindrical (the eleventh, how- 

 ever, is conspicuously longer than the tenth), the combined
