36 Mr. Gilbert J. Arrow's Cunlributiun to the 



similis Weise and Helioblelus servilis Gorhani, have all 

 unfortunately been described from female types, and it 

 may never be possible to establish with certainty the 

 essential diagnostic characters of their species. The types 

 of the first and last are in the British Museum. 



Besides the curious differences in the antennae and legs, 

 the males of Danae. are generally more elongated than the 

 females, owing to the enlargement of the metasternum and 

 1st abdominal segment and the consequent lengthening 

 of the elytra. The hind legs are generally longer, placed 

 farther back and frequently toothed at the inner edge of 

 the fenuir or tibia. 



Dr. Marshall found these insects at the roots of grass in 

 damp places. 



In a male specimen which I believe to agree with the 

 female type in our collection of Danae rufvla Reiche, the 

 middle and hind tibiae are curved as in Danae naialetisis 

 Gerst., and the club of the antenna alone is black, but it is a 

 rather larger species and more shining, the punctures upon 

 the pronotum especially being fairly close but less coarse. 

 The pronotum is also relatively wider, with more dilated 

 margins. The supposed difference between Danae rufula 

 Reiche and D. 6??/6r/"tT« Weise, described by Weise (viz. the 

 marginal sulcus not diverging to the hind angle in the 

 former) has no real existence but, from the size, Danae 

 biilbifera is perhaps more likely to be Danae natalensis. 

 Gerstaccker's figure of the latter, upon which Weise relied, 

 is worthless and does not correspond with the description. 



No species laiown to me has the 9th joint of the antenna 

 shaped quite as represented in Danae j)ulc}iella Gestro, 

 and Danae senegalensis Gerstaecker, is probably also 

 different from any species in our collection.
