A NEW SPECIES OF ERYTHRONEURA 

 (TYPHLOCYBID^, HEM.-HOM.). 



By J. R. Malloch, Urbana, Ills. 



The type specimen of the species described herein is deposited 

 in the collection of Illinois State Natural History Survey. 



Erythroneura sexpunctata, sp. n. 



Male — Head yellow, with faint reddish markings, two round 

 dots on vertex, a broad stripe on each side of face on its upper 

 half, and the center of clypeus black. Pronotum dusky on 

 sides, with two faint reddish vittae in center, and two small 

 black dots near anterior margin. Scutellum red at apex ; with 

 a large black spot at each anterior lateral angle. Pleura largely 

 black. Tegmina with a broad fuscous stripe extending from 

 base to apex in center, touching costa from base to proximal 

 extremity of costal placque and for a short distance at distal 

 extremity of same, and inner margin at middle of clavus and in 

 base of fourth apical cell ; inner margin of clavus narrowly red. 

 Legs yellow. Abdomen fuscous, segments narrowly pale at 

 apices ; hypopygium yellow. 



Vertex rounded in front, its length at center barely more than 

 half its posterior width from eye to eye. Venation similar to 

 that by vidnerata Fitch, the second apical cell noticeably shorter 

 than third, and the veins forming base of fourth angulated, the 

 vein extending to radial margin, however, at right angles to 

 that margin whereas in vulncrata it is slightly sloped apicad at 

 its inner extremity. Hypopygial claspers stouter than in viih 

 nerata, but structurally similar. 



Length, 3.5 mm. to apices of tegmina. 



Type, Muncie, 111., December 13, 191 3 (Hart and Malloch). 



This species was recognized as new by Mr. Hart and the name 

 used here is the one he had on the label in our collection. 



According to McAtee's recent key to the species of this genus 

 this species falls into the section with vidnerata Fitch and the 

 characters in the above description will serve to separate it from 

 that species.
