MORGAN HEBARD I 23 



Type. — d" ; Raleigh, North Carolina. June i8. 1904. (C. S. 

 Brimley.) [Hebard Collection, Type Xo. 425.] 



Description of Type. — Size medium fcir the genus, form moderately slender. The 

 cephalic and pronotal features agree throughout with Julvescens. Head rather 

 e\enly rounded, with ocelli well defined, but margin of ocellar areas rounding rather 

 weakly into the inter-ocular-ocellar area, which is feebly flattened, weakly convex, 

 showing a few microscopic punctae. Interocular space intermediate in width to 

 that separating the ocelli and that between the antennal sockets. Pronotum 

 Avith greatest width slighth- caudad of mesal point, with cephalic angles more 

 broadly rounded than caudal angles and oblique sulci of disk weakly defined. Teg- 

 mina and wings normal. fulK' developed; tegmina, as m fiilvescens. with greatest 

 width very slightly greater than that of pronotum. Median segment supplied 

 mesad with two small and weak elevations, with cephalic faces of each furnished 

 with a heavy tuft of hairs, the surface of the segment is also supplied cephalad of 

 these with a few minute, scattered hairs. First dorsal abdominal segment simi- 

 larly specialized in every wa\-, except that the minute scattered hairs are less numer- 

 ous. Sixth dorsal abdominal segment with distal margin transverse, showing very 

 broad and feeble concavit}- laterad and similar convexity mesad. Supra-ana! plate 

 with lateral margins nearly straight, convergent to bluntly rounded apex, surface 

 of plate feebly convex abo\-e cerci, in remaining portion weakly concave and decli- 

 \-ent distad. Cerci slender and elongate. (.lenital hook concealed, adjacent proc- 

 ess as found \n fiilvescens. Subgenital plate weakly convex to immediate bases of 

 styles, where it is weakly concave, lateral margins nearly straight and weakly con- 

 vergent to styles, but the sinistral margin showing a feeble concavity distad. distal 

 margin between the styles nearly straight, transverse; styles small, simple, cylindri- 

 cal processes, situated in sockets on \entral surface of plate at disto-lateral angles, 

 in length each slightly less than the space inter\-ening between their bases. Ex- 

 posed folded ventral portion of seventh dorsal abdominal segment in length equal 

 to exposed portion of ninth \X'ntral aljdominal segment. 



The series of males before us shows the following variation. Size individually 

 variable but with some geographic significance. Interocular space occasionally no 

 wider than width between ocelli. Pronotum with discal sulci sometimes subobso- 

 lete. Wings with two to four incomplete and four to five complete rami of the 

 ulnar vein. Sui^ra-anal jilate with apex varying from rather shar])l\- to rather 

 broadK' rounded and with concave surface rareh' showing a feel:)le. transverse, 

 weaklv arcuate ridge, a feature normalK' rather i)rominent in fiilvescens. Sub- 

 genital plate with distal couraxit)- of sinistral margin occasionalK- more i:)ronounced. 



Allotype. — 9 ; Spartanburg, South Carolina. August 6, 1913. 

 (M. Hebard.) [Hebard Collection.] 



Description of Allotype. — Size smaller than male. Head more evenh' rounded, 

 but with ocellar areas still i)resent, though weakly defined, and ocelli approaching a 

 condition of large ocellar spots. Interocular space broader than in male, nearh- as 

 wide as width between the more wideK- spaced antennal sockets. Pronotinn jiro-
