NO.1310. NORTH AMERICAN THY8AN0PTEBA— HINDS. 127 



The genus ^EolotJirips is the only one of the three genera of this 

 family found in the United' States. 



Genus .^OLOTHRIPS Haliday. 



Head about as broad as long-. Ocelli present in Ijoth sexes. Anten- 

 na? nine segmented, the last three or four segments being very much 

 shorter than the preceding and closel}' joined together; third segment 

 much longer than any other. Maxillary palpi three segmented, 

 geniculate. Prothorax about as long or a little longer than the head, 

 without large bristles. Legs very long and slender; fore femora 

 somewhat thickened in both sexes; hind femora broadened; fore tibije 

 unarmed; second fore tarsal segment, in both sexes, wdth hook-like 

 appendage. Wings usuall}^ present in ))oth sexes; fore wing some- 

 what narrowed before the middle; fore part of the ring vein fur- 

 nished with very short hairs, which hardly overreach the edge of the 

 wing. Fore wings Avhite, with two broad, dark cross bands. First 

 abdominal segment in the males much longer than the second, and the 

 ninth segment is drawn out at the hind angles into short clasping 

 organs or hooks. 



The two species which I place here can be distinguished by the 

 presence of a white band around abdominal segments two and three in 

 the female of ^1. l>ieoloi\ which band is wanting in the female of A. 

 fasciatii><. The last four segments of the antenna taken together are 

 much longer in A. hlcolor than the fifth, while in A. fmclatus the last 

 four segments together are approximately as long as is the tifth alone.
