A NEW SPECIES OF ROPTRONIA. 

 By WILLIAM H. ASHMEAD. 



The following new species in the rare genus Roptronia Prov. 

 was taken by Prof. H. Garman, of the State College of Ken 

 tucky, at Lexington, Ky., and after whom I take pleasure in 

 naming the species. 



The genus, as originally described, was placed by Abbe Pro- 

 vancher in the family Braconidce, but was subsequently removed 

 by him to the subfamily Helorince in the Proctotrypidcz. From 

 the imperfect figure of the venation given by Provancher, and 

 before I had seen a specimen for examination, I was inclined to 

 doubt the correctness of this last view of the learned Abbess, and 

 placed the genus doubtfully among the aberrant group Pachy 

 lommatince in the Braconidae. Since that time, however, I have 

 seen three representatives of the genus, and a careful study of 

 these specimens convinces me that Provancher was correct in 

 removing the genus to the Helorinae. The venation is somewhat 

 similar to the genus Monomachus Westw., and seems to afford 

 a connecting link between this genus and the genus Proctotrypes 

 Latr. 



Monomachus should also be placed with the Helorinae. 

 Roptronia garmani, n. sp. 



(j\ Length 7.5 mm. Black; head and thorax rugoso-punctate, pubes 

 cent; front coxae, except a spot at base beneath, trochanters, except spot 

 above, tips of femora and anterior tibiae and tarsi, spot at apex of middle 

 coxae, second joint of trochanters, tibiae beneath and narrowly at base 

 and apex and their tarsi, second joint of hind trochanters and basal one- 

 third of hind tibiae, pale ferruginous or pale yellowish; tegulae and pro- 

 thoracic tubercles ferruginous. Head transverse-quadrate, the temples 

 as wide as the eyes ; mandibles dull ferruginous, bidentate at apex, the 

 upper tooth longer than the lower; maxillary palpi 5-jointed, labials 4- 

 jointed, the last joint dark fuscous. Antennae 14-jointed, filiform, taper 

 ing off at apex. Thorax, with the mesonotal furrows rather broad, dis 

 tinct, slightly crenulate, especially posteriorly; metathorax rugose, 

 rounded off posteriorly, the spiracles small oval. Abdomen with a long 

 petiole, the petiole being fully as long as the hind femora, or slightly 

 longer, shining, but fluted above, and somewhat rugose basally, smoother 

 and punctate towards apex and beneath, pubescent, body of abdomen com 

 pressed, viewed from the side somewhat triangular, about as long as the 

 petiole, highly polished, the first segment occupying fully two-thirds the 

 whole length, the following segments short, subequal. 



Hab. Lexington, Ky. (Prof. H. Garman.) 



Quite distinct from ./?. pediculata Prov. in its much larger 

 size and in the color of legs and abdomen. In R. pediculata 

 the abdomen is red, the hind legs black, &c.
