CHARLES W. HOOKER. 143 



Thoracic sutures, pectus and coxas sometimes ferruginous ; meso- 

 notum smooth, with three broad longitudinal fuscous stripes of equal 

 length, the median half its length in front of the others ; scutellum 

 prominent, convex, hollowed in front, and bordered with lateral keels 

 connecting with the mesonotum ; metathorax with an anterior trans- 

 verse carina, in front of which it is smooth, behind wrinkled, with a 

 shallow median longitudinal furrow and arcuate carinae originating 

 around the insertion of the abdomen. 



Wings hyahne, sometimes slightly tinged with fulvous ; nervures 

 flavo-fuscous, stigma flavous ; radial vein angularly broken about 1 

 mm. from the stigma, thickened beyond the break ; discocubital cell 

 with a small glabrous area inclosing one or two indistinct, colorless, 

 irregular spots ; discocubital vein sinuous ; nervulus antefurcal ; ner- 

 vellus broken well below the middle. 



Legs fulvous, claws pectinate. 



Abdomen smooth and shining ; beyond the first or second or middle 

 of third segment fuscous, the remainder flavous ; the whole body 

 sparsely clothed with fine short pubescence. 



Redescribed from two females ; one male specimen from 

 Peru compared with the original description. 



Type. — Location unknown. 



Distribution. — Brazil ; Haituba, Peru. 



This species is evidently tropical, having been taken in 

 Brazil and Peru, and probably inhabits Bolivia and Ecuador, 

 possibly going into Colombia, Venezuela, and Guiana. I can 

 find no reference to this species since Brulle's original descrip- 

 tion of a specimen from Brazil, but there are in the Massa- 

 chusetts Agricultural College collection several specimens 

 from Peru which seem to agree with Brulle's description. 



Life history. — I can find no reference to the life history, 

 habits or hosts of this species, and hence can give no idea of 

 its economic value as a parasite. 



Location of specimens . — Massachusetts Agricultural College, 

 two 9 's and one c? from Peru. 



Ereniotylus fiavofiiscus radialis n. subsp. 



I consider as a subspecies two female specimens from 

 Peru which differ from flavofuscus in that the radial nervure 

 is evenly bent, not angularly broken. 



Cotypes. — Two 9 's, Peru, Massachusetts Agricultural Col- 

 lege.
