No. 2320. TRIBE ACOENITINI—CUSHMAN AND ROHWER. 517 



the rest of the thorax; nervnlus antefurcal by only twice its width; 

 areola defined laterally; face with distinct punctures which dorsally 

 have a tendency to transverse striato-punctation. 



Walsh lists three females and one male, and says the terminal edge 

 of the wings is clouded with dusky. His specimens are lost, so it is 

 impossible to say that they are the same as the Cresson type. 



Both the type and the specimens listed by Walsh were collected in 

 Blinois. 



AROTES MAURUS Rohwer, new species. 



This new species is probably more closely allied to formosus Cresson 

 than to any other described form, but the much darker head and 

 thorax readily distinguishes it from that. 



Female. — Length, 18 mm.; length of ovipositor, 18 mm. Clypeus 

 depressed basally; face with a median dorsad-ventrad raised line, 

 irregularly wrinkled on each side of this line, shining and with well 

 separated distinct punctures laterally; frons, vertex, and temples 

 smooth, without sculpture; ocelli in a low triangle; the postocellar 

 line one-third shorter than the ocellocular line; scutum polished; 

 notauli feebly foveolate; suture in front of the scutellum with many 

 rugae; ridges on propodeum strong; basal area wider than long; 

 parallel-sided, separated from the areola; areola and petiolar areas 

 confluent ; mesepisternum with a distinct episternal depression which 

 is polished, impunctate, rest of episternum shining, with distinct 

 punctures; sides of propodeum confluently punctate ; recurrent inter- 

 stitial in one wing, distinctly antefurcal in other. Black; band on 

 apical margin of clypeus confluent with narrow line (dentate opposite 

 antennae) from near top of eye, spot on cheeks, tegulae, scutellum 

 and metascutellum, and apical margins of first, second, and third 

 (interrupted medianly and laterally on third) tergites reddish yellow; 

 legs black; apex of anterior coxae, spot on intermediate coxae, tro- 

 chanters, anterior and intermediate femora beneath, four anterior 

 tibiae and tarsi, basal half of posterior tibiae and posterior tarsi yel- 

 lowish; antennae black, with a broad yellowish annulus beyond the 

 middle; wings hyaline, slightly yellowish with the apical margin 

 dusky; venation, including stigma, dark brown. 



In the paratype the areola and petiolar area are distinctly sepa- 

 rated and the yellow line on inner eye margins is interrupted below. 



Type locality. — Mssion, British Columbia. Described from two 

 females.
