L. staphyleae Knight. 



Ent News, xxviii, 460, fig. 4, 1917. 



Male: Length 6.5 mm., width 2.05 mm. ; orange-yellow, fuscous 

 on calli, narrowly at base of pronotum, scutellum, apical two-thirds 

 of clavus, inner half of corium, and membrane ; antennae, tylus, 

 two bars on front, base of head, rostrum, and legs, black; the 

 fuscous shading on the dorsum much paler than in robiniae; 

 genital claspers (fig. 76), distinctive of the species. Antennae: 

 Segment i, length .71 mm., thickness .15 mm. ; ii, 2.48 mm., thick- 

 ness .10 mm., tapering slightly smaller on apical half ; iii, 1.82 mm., 

 slender and almost linear; iv, .52 mm. 



Female: Length 6.8 mm., width 2.2 mm.; similar to the male 

 in structure and coloration, but usually slightly larger. Sometimes 

 very similar in size and coloration to the female of confluens; but 

 the length of antennal segment i in confluens is shorter than the 

 width of vertex, while in staphyleae its length is as great as, or 

 slightly longer than, the width of vertex. 



Food plant: American bladder nut (Staphylea trifolia).

*L. staphyleae var. sanguinea Knight. 



Ent. News, xxviii, 461, 1917. 



Male: Size, structure of the antennae and male genital clasper 

 not differing appreciably from the typical staphyleae, but the 

 yellow coloration replaced by bright red. 



Female: Similar to the male in structure and coloration; very 

 much resembling the females of reuteri and caesar, but the more 

 slender form of the antennae will serve to distinguish this variety. 



In Minnesota the writer has taken a large series of this variety
