IIVOTES ON SOUIE HEMIPTERA FROM BRITISH 

 GUIANA. 



BY EDWARD P. VAN DUZEE. 



During the past summer I have been receiving from Mr. R. J. 

 Crew certain families of the Heteroptera collected by him about 

 Bartica, British Guiana. So few collections in this order have been 

 reported from this interesting country, it seemed to me that an an- 

 notated list of the material received might be of value especially as 

 this list includes the names, of some species not before recorded from 

 that district. In addition to the 89 species here recorded the lot 

 included some forms I have as yet been unable to place satisfactorily. 

 The species are arranged nearly as in Lethierry and Sevrin's Cata- 

 logue. 



Superfaraily PENTATOMOIDEA. 



Corimelaena tibialis Fabr. — April, May and Sept., three ex- 

 amples. A tiny little species about half the size of pulicaria which 

 it somewhat resembles. 



Corimelaena Daldorfi Fabr. — March, May and Sept., five ex- 

 amples. Apparently common. A pretty species variegated with 

 orange and black. 



Corimelaena spp. — There are in this lot several examples rep- 

 resenting two species both closely allied to notatipennis Stal, but 

 wanting the pale spots at the apex of the corium. More material 

 and further study is necessary to properly locate these species. 



Corimelaena rastrata Stal. — March, May and Sejjtember, five 

 examples. 



Corimelaena Schmidti Fabr. — Many examples taken from May 

 to September. This species pertains to the section of the genus having 

 the scutellum shorter than the abdomen. I place it here with hesita- 

 tion. It agrees well with Stal's description in the Hemiptera Fabrici- 

 ana except that it has the additional pale point at the apical angle of 

 the elytra as described by Germar. But Germar's species has the long 

 scutellum and has been named notatipennis by Stal. This species is 

 so well represented in the material sent by Mr. Crew that I cannot
