June, 189s.] Dyar : New Species and Larvae of Sawflies. 129 



Claws simple ; anal vein in front wings curving upwards at tip ; transverse 

 cubitus in hind wings very short, the anal cell lorjgly petiolated. O $ • 



Blennocampa Hartig. 



11. Third transverse cubitus curved inwardly, not extending in the same direction 



with the transverse radius, strongly divergent ; third submarginal cell larger 

 than the first and second united ; pedicel as long as the scape, about thrice 'as 



thick. $ Calozarca Ashm. g. n. 



(Type fascipennis Nort. ) 

 Third transverse cubitus straight or nearly so, and running in the same direction 

 with the transverse radius ; third submargical cell hardly longer than the sec- 

 ond, much smaller than the first and second united ; pedicel shorter than the 

 scape. $ . Erythraspides Ash?n. 



12. Third transverse cubitus in front wings not running in the same direction with the 



transverse radius ; marginal cell in hind wings with an appendage ; third joint 

 of antennae much shorter than joints 4-5 united ; claws with a small tooth 



within .Scolioneura Konow. 



Third transverse cubitus in front wings almost interstitial with the transverse ra- 

 dius, and running in the same direction ; marginal cell in hind wings without 

 an appendage, sometimes open at apex ; claws with a strong triangular tooth at 

 base Entodecta Konow. 



13. Hind tarsi usually longer than their tibiae ; clypeus very small, transverse-linear. 



antennae densely pilose, the third joint longer than the fourth. O $ • 



Zarca Cameron. 



Hind tarsi not longer than their tibiae ; clypeus not small, anteriorly subemargi- 



nate or truncate. 



Antennae pubescent, the third joint distinctly longer than either the fourth 



or the fifth. 



Third submarginal cell longer than the first and second united ; antennae 



long, tapering toward tips, the third joint about as long as joints 6-9 



united o : , Calozarca Ashm. 



Third submarginal cell not longer than the first and second united ; 

 antennae with the third joint usually not longer than joints 9-10 



united ; Monophadnus Hartig. 



Antennae clothed ^ ith long appressed hairs, the third and fourth joints equal, 

 the fifth longer, all somewhat thickened toward tips. . Senoclia Cameron. 



Periclista diluta Cresson. 



These larvae are briefly described from Riley's notes in Packard's 

 Forest Insects (5th Rept. U. S. Ent. Coram., p. 206), but without giv- 

 ing the most essential characters. The bred flies in collection U. S. 

 Nat. Mus., have the lanceolate cell of hind wings unusually long, though 

 still shortly petiolate at tip. 

 Periclista purpuridorsum, sp. nov. 



$ . Black, segments 2 to 4 of tergum dull luteous ; angles of prothorax (except a 

 black dot) aid tegulae white ; tip of clypeus and labrum pale. Legs black at base, 

 ends of femora and tibiae whitish and brown, tarsi duskv, nervures brown black ; 

 second recurrent received at base of third submarginal cell, almost interstitial.
