19G UEVISION OF PTEROHEL.i:US (coutd.) AND SARAGUS, ETC., 



however, were sent by Mr. H. Giles, in company with undoubted 

 specimens of .V. opacipennis, from which it differs in shape, and 

 in the absence of the fourth costa (on the sides). The latter is 

 often subobsolete in .S'. opacipennis, so that the two species are 

 very closely allied, if not mei'ely varietal forms. 



Section ii. Elytra reticulate. 

 38. (40)Elytra with reticulation clear(j.e., trans verse lines evident in general ) 



39.Proiiotuni granular, elytral costae sharp, reticulation less regular 



reticAdatus Haag-Rut. 



40.Pronotuni punctate, elytral cost* smooth and flat, reticulation verj' 



regular in t ricalu» Cha,mT^. 



41.(47)Elytra with reticulation ol.scure (i.e., transverse lines generally 



wanting). 

 42.(46)Suture not raised. 

 43.(45)Elytral intervals granular.

45.Pronotuni more densely punctate, elytral intervals less undulate 



cremdatns Macl. 



46. Elytral intervals rugose-punctate clathratus Mad. 



47. Suture costate, margins of pronotum thickly folded. . rugodpennis Macl. 



The above are all quite distinct species, with the exception of 

 S. Iii:rklus Haag-Rut., and S. crenvlatus Macl., which may prove 

 to be merely varieties of the same species.
