OF WASHINGTON. 133 



I add below the description of another species discovered among 

 the collection of Braconidce, belonging to the American Ento 

 mological Society, now in my hands for examination and study. 



Roptronia californica, n. sp. 



<$. Length 5.5 mm. Pale ferruginous; spot on vertex enclosing the 

 ocelli and extending forward to base of antennae, occipital foramen, clypeal 

 spiracles, prothorax above anteriorly and beneath, mesopleura, meta- 

 thorax and abdominal petiole, black ; eyes brown ; antennae, except pedicel, 

 brown, i4-jointed ; legs pale brownish-yellow; wings hyaline, the stigma 

 and veins brown. 



This species structurally does not differ greatly from R. garmani, except 

 in having the head, except vertex and face, the mesonotum and the scu- 

 tellum, except at apex, smooth and almost impunctate; the mesopleura, 

 except space beneath wings, are closely punctate, while the metathorax 

 is rugose. The venation is almost identical in the two species, except in 

 californica, the first abscissa of the radius is perpendicular and not longer 

 than the width of the stigma, while in garmani it is oblique and more than 

 twice longer than the width of the stigma. Another character not noted 

 in the other two species is that the postscutellum is conically produced, 

 viewed from the side its apex reaches an elevation above the disk of the 

 scutellum. 



Hab. Southern California. 



The three species now known in this genus may be tabulated 

 as follows : 



Head and thorax black, rugose ; postscutellum normal. 



Abdomen black ; legs, except tips of anterior and middle femora and 

 their tibiae and tarsi, mostly black. $. Length 7.5 mm. 



R. garmani Ashm. 

 Abdomen red; legs, except coxae and hind legs which are black. 



rufous. 9- Length 6.75 mm R. pediculata Prov, 



Head, except spot on vertex and frons, mesonotum, scutellum and abdo 

 men, except the petiole, pale ferruginous; postscutellum conically ele 

 vated; legs pale brownish-yellow. <j\ Length 5.5 mm. 



R. californica Ashm.

It had been my intention to simply submit for publication the 

 descriptions which follow, of two new genera of Aphelininae,
