ON SOME RHYNCHOTA OF ECONOMIC IMPORTANCE FROM COLOMBIA. 



By W. L. Distant. 



(Plate V.) 

 The Imperial Bureau of Entomology have received the following six species of 

 Rhynchota from Colombia, forwarded by Mr. M. T. Dawe, the Director of Agriculture, 

 who reports two of them Trichocentrus sp., and Collaria oleosa as injurious to rice 

 plantations, and the remaining four, Monalonion atratum, M. ilhistris, M, megiston, 

 and M. collaris as damaging cacao pods. Of these Monalonions, two are here 

 described as new species. 



Fam. LYGAEIDAE. 

 Sub-fam. Colobathristinae. 



Trichocentrus gibbosus ? (PI. v, fig. 3). 



Trichocentrus gihhosus, Horv., Ann. Mus. Nat. Hung, 1903, pp. 119 and 153. 



Dr. Horvath proposed this new genus for a species he described from the Rio Grande, 

 and Mr. Dawe's specimens, from the character " pronoto antice tumido-elevato, 

 capite multo altiore," seem to belong to the genus and possibly to the same species. 

 The present war however prevents any comparison or loan of types. 



Mr. Dawe reports that the species above referred to " attacks rice plantations." 



Fam. CAPSIDAE.
