her egg in that of the sawfly. Another parasitic Ichneumon attacking 

 this pest in America is ffemiteles ncmcttivorus, Walsh, parasitic on 

 the larva?. 



The larva? are also attacked by one of the " laud bugs " (Podiscus 

 placidus, Uhler), which sucks out the body juices of the pests by 

 means of its piercing proboscis. This hemipteron lias black head, 

 legs, thorax, and a red abdomen with a long black central spot 

 crossed by a white line.

THE ALLIED GOOSEBERRY SAWFLY. 

 (Xcmatux consobrinus. Toll.) 



This insect is by no means as common as the former, but 

 occasionally it is sent with inquiries. It occurs in Holland, Prussia 

 and Siberia, as well as in Britain. 



It also appears to be known under the name Ncmatus umbrinus, 

 Zaddach. The female is slightly smaller than X. ribesii, but the 

 males are much the same size. The female differs in having more 

 yellow on the head, the scutellum and metanotum black, and 

 the abdomen dark basally and showing basal median, dark bands 

 and patches to most of the segments, and in some, most of the 

 dorsum is dark to the seventh segment. Eyes surrounded with 

 brown. The thorax is black, minutely punctured, the pronotum 

 being pale fulvous ; the legs are pale fulvous ; base of the coxa?, apex 

 of the posterior tibia? and tarsi black ; base of the femora and 

 tibia? pale. The wings are hyaline and iridescent, and the base of 

 the costa is testaceous, the stigma dark testaceous.
