when food is not so abundant. The ai)parent rarity of sexual 

 jn-opagation, which nii^lit possibly k'ad to tlic ibrmation of 

 cocoons so small as to be icadily carried about by the wind, 

 may liave something to do with tliis encystment. The cyst3 

 are small enough to travel very easily, and the wide distribu- 

 tion of the species may have been thus brought about.

In my two papers on this group of Longicornia which have 

 already appeared 1 have dealt with African, Indo-Malayan, 

 and Australian species. The present contribution is conhned 

 to South -American species of the group. 



Ilammaticlierus macrus, Bates. 



Mr. Bates's clear description of this species leaves no room 

 for doubt that it is identical with the lianwiaticJierus hellator 

 of Dejean's collection. It is very doubtful, however, whether 

 Serville's description could possibly have been drawn up 

 from the same species ; if it is to be accepted as accurate we 

 must regard the //. hellator of Serville as a species allied to 

 but quite distinct from //. macrus. Bates { = H. hellator^ 

 Dej.). It may be remarked that in the latter species the 

 anterior cotyloid cavities are distinctly open behind, while in 

 all the other species known to me they are completely or 

 almost completely closed in behind. 



Hamnudicherus eonsobrinuSj sp. n. 

 Ploccederus consohrinus, Dej. Cat. 



Fulvo sat dense pubescens ; prothorac^J supra transversim regula- 

 riterque plicato, lateraliter in medio modice tuberculato ; elj-tris 

 fulvesceutibus, apicibus truncatis, utrisque bispinosis ; articulis 

 autennarum a tertio ad decimum apice intus spinosis, articulis 

 tertio quartoque spinis recurvis. 



Long. 26, lat. 8 mm.
