Biological Notes on Reared Parasitic Hymenoptera.

aborted galls of the Lasioptera. The galls from which types 

 of all the species mentioned were reared, were sent me by 

 Prof. McFadden, of Westerville, near Columbus, Ohio. 



Meniscus 4-cinctus Ashmead. Of this I can only state 

 that the types were reared by myself from a chrysalis, found 

 in the folds of a peach leaf, collected on Catawba Island, Ohio, 

 on the shore of Lake Erie. For description see beyond. 



Clinocentrus tarsalis Ashmead. The types of this 

 species were reared under rather peculiar circumstances. 

 For some time my botanical friends in Columbus have com- 

 plained of the ravages of an herbarium pest, probably the larvae 

 of a species of Pyralid, which destroyed dried specimens of 

 plants of the genus Gentiana. Although the depredator would 

 not be observed at the time the plants were collected and 

 pressed, soon after this the bloom would be attacked, and later 

 oil the foliage would be also destroyed, the larvae finally eating 

 holes in the papers and later transforming to the chrysalis 

 without constructing a cocoon. While attempting to rear the 

 adult moths from material sent me by my friend Prof. Selby, 

 of the Columbus high school, this species emerged in the 

 breeding jar where the Gentiana feeding larvae were confined. 

 Not being successful in rearing the moths, it is, of course, 

 impossible to give the name of the host. For description, see 

 Mr. Ashmead's paper. 



Pezomachus obscurus Cresson. Reared at Columbus, 

 Ohio, from eggs of spider,* which eggs were enclosed in disc- 

 shaped nests and fastened to the surface of stones. Previously 

 described from New Jersey. 



HemitelES drassi Riley. Types reared with the preced- 

 ing, at Columbus, Ohio. The female has not yet been 

 observed, at least so far as published record goes, and while it 

 might be too much to state in a positive manner, yet it is 

 quite possible that this sex is confused with other species. 

 The host is a Drassid spider. Described in Proc. Ent. Soc. 

 Wash., Vol. II, p. 296. 



Eurytoma studiosa Say. Reared from Dipterous galls 

 on Erigeron canadense L-, at Lafayette, Indiana. Description
