Stethynium peregrinum, new species. 



A species at once distinguished from the type species of the 

 genus (triclavatutn Enock) and the American species (/annum 

 Girault) by bearing decidedly broader posterior wings which 

 are very broad for a myuiarid, nearly as broad as the fore 

 wings of some Anagri (e.g., Anagrns armatus Ashmead). 

 Comparing it with fait num (actual specimens), it is twice more 

 robust (easily visible to the eye, for instance, faninim being 

 minute thus) and distinctly different in color, being reddish 

 brown (about Indian red), while /annum is yellow (gamboge) ; 

 the antenna differs in bearing shorter funicle joints, the sec- 

 ond funicle joint, for instance, not slender and relatively long, 

 thrice longer than wide, but only about a third longer than 

 wide and no longer than the third joint; also the antennal 

 club is decidedly longer in peregrinum. The fore wings in 

 this species are much broader than in f annum and differ in 

 shape, in that the apex is not an obtuse point but regularly 

 rounded; moreover the marginal cilia are decidedly shorter 

 in peregrinum. 



NORMAL POSITION. 



Female. Length 0.73 mm. Large for the genus. 



General color uniformly reddish brown, the antennae, venation, and 

 legs dusky brown, the distal tarsal joints dusky. Eyes dark red. 

 Fore wings irregularly, rather lightly, fumated proximad under the 

 venation, especially at the dilatation or caudal lobe along the posterior 

 margin, and both wings with a slight dusky appearance throughout. 

 Pronotum and vertex occasionally fuscous. 



Fore wings about as in the type species in regard to width, broad 

 yet not especially large, densely and finely ciliate in the disk, the 

 blade ovate in shape; bearing about from 30 to 34 lines of discal cilia 

 across the widest portion; marginal cilia comparatively short, the 

 longest only about a fifth the greatest wing width, short at the apex. 

 Blade of the posterior wing broad (nearly as in Gonatocerus dolicho- 

 cerus Ashmead, but broader) , but not any broader across the apex of the 

 venation, broadest somewhat beyond its middle, with a single line of dis- 

 cal cilia along the cephalic margin and a paired line along the caudal mar- 

 gin; within, the blade bears about three lines of discal cilia which are 

 somewhat irregular; all discal ciliation fainter proximad. Marginal 

 cilia of the caudal margin of the posterior wing long, distinctly longer 

 than the longest cilia of the fore wing, about twice longer than the 

 greatest width of the blade of the posterior wing, or not quite that 

 long. In the fore wing there is a small naked area just out from the 

 end of the marginal vein; this area is longer than wide. 



Tarsi four- jointed, all the joints short, subequal, the proximal joint 

 in the cephalic tarsi somewhat longer; tibial spurs single, acute,
