The Identity of Two Insects, each Described by 



Ashmead as Megastigmus flavipes (Hym.) 



By C. R. CROSBY, Ithaca, N. Y. 



In 1886 Ashmead described Megastigmus flavipes (Trans- 

 actions of the Ajmerican Entomological Society; v. 13: p. 128). 

 In the United States National Museum there remains the pin 

 on which the type was originally mounted, glued to a paste- 

 board triangle. Only the hind legs and one front wing remain. 

 The stigmal club is large, very dark colored, and appears to be 

 surrounded by a narrow clearly defined cloud. These charac- 

 ters prove it to be a true Megastigmus. 



In 1888 Dr. Ashmead described another insect under the 

 same name, Megastigmus flavipes. (In Bulletin 3, Kansas 

 Agricultural Experiment Station: p. III). Through the kind- 

 ness of Professors T. J. Headlee and G. A. Dean, I have been 

 able to examine the type of this species. It is a male Torymus. 

 In transferring it to that genus, we find the name Torymus 

 flavipes preoccupied by Callimome flavipes Walker (Entomo- 

 logical Magazine; v. i : p. 124. 1833) also a true Torymus. It, 

 therefore, becomes necessary to change the name of Ashmead's 

 species, and as the original description was very inadequate, 

 I have drawn up the following : 



Torymus abortus new name.

Male. Length, 1.5 mm. Head and thorax metallic greenish blue. 

 Front and face finely reticulate-punctate, vertex becoming delicately 

 transversely rugulose. Antennae dusky. Posteriorly on the thorax 

 and on the pleurae a brownish ground-color shows through the green. 

 Dorsum of thorax finely and densely pustulate ; no transverse stria on 

 scutellum. Propodeum not in a position for study. Pleurae and coxae 

 brownish with greenish metallic reflections. Abdomen dark brown 

 with aeneous reflections. 



Front and middle legs pale yellow ; hind femora and tibiae broadly 

 infuscate. Wings hyaline.
