Wings hyaline; third vein curving backward before tip so 

 that it ends very sHghtly behind the extreme apex ; hind cross- 

 vein straight. 



Female. Front legs much more infuscated, only the coxae 

 and base of femora yellow, front femur not with tuft ; tarsi 

 black ; palpi widened and considerably blackened, prominent. 

 Abdomen normal, with four pairs of spots ; those on first and 

 second segments triangular and brownish, the other two pairs 

 smaller, roundish, black ; a trace also of a dark median stripe. 



Length, 3.1 to 3.7 mm. 



Described from many Hawaiian specimens. 



As already stated, there are no published references to the 

 early stages that I know of. I have seen no larvae ; but puparia 



Fig. 2 — Puparium of Atherigona piilvinata Grimsh. Viewed from the 

 left side. Anterior end shown at left and posterior at right ; the 

 larval anal opening below at right end, and the posterior spiracle 

 more enlarged above at right. (Drawn by C. T. Greene.) 



are pinned with several of Mr. Back's Hawaiian specimens, 

 and with one of Woglum's from Hermosillo, Mexico. From 

 the latter, Mr. C. T. Greene very kindly made me a drawing 

 (fig. 2), showing its singular characters; the Hawaiian speci- 

 mens show no differences. 



Instead of forming an elliptical body, the puparium is trun- 

 cated at both ends, like a barrel, only longer in proportion. 

 The anterior end has a distinct circular rim but little smaller 

 than the diameter at middle of body ; the anterior spiracles are 

 not located behind the rim as one would expect, but are drawn 

 in nearly to the center of the flat anterior disk, as figured. 

 Other characters are as figured.
