Luteoiis to fulvous ; antennce^ vertex and third to eighth segments of the 

 abdomen black, wifigs hyaline, stigma black, discocubital cell with two 

 macules. 



Length, 22-25 mm. ; wing, 18 mm. ; spread, 38 mm. ; antennse, 25 

 mm. 



Luteous to fulvous, eyes and face flavous, vertex black ; ocelli large, 

 prominent, well separated ; antennae black, slender, about as long as 

 the body ; thorax of the general color ; mesonotum more or less tinged 

 with black, scutellum long and narrow, with distinct lateral keels ; 

 metathorax with strong anterior transverse carina in front of which it 

 is smooth, behind coarsely reticulated, with median keels straight at 

 the base, then diverging towards the sides.* Wings hyaline, irides- 

 cent ; stigma and nervures black ; basal half of radial vein slightly 

 thickened ; discocubital cell with two maculae, the larger subtri- 

 angular, the smaller varying from circular to almost crescentic ; dis- 

 cocubital vein with the outer two-thirds nearly parallel to the discoidal 

 vein ; first recurrent vein one-half the length of the second ; nervulus 

 antefurcal to interstitial ; nervellus broken far below the middle ; legs 

 of the general color, claws pectinate. 



Abdomen with the two basal segments subequal, the first becoming 

 gradually thickened toward the apex ; segments 3 to 8 black. 



In redescribing this species I have compared one specimen 

 with the original description. 



Cotypes. — Two 9 's, British Museum. 



Distribution. — This species is apparently tropical or sub- 

 tropical ; the two cotypes were taken at Las Mercedes, Guate- 

 mala, at 3,000 feet, and San Indro at 1,600 feet, and I have 

 specimens before me from Mexico and from Santo Domingo, 

 West Indies. 



Nothing is recorded of the life history, habits or hosts. 



* Cameron says "with a transverse keel towards the basal half, be- 

 hind which it is smooth ; in front of it coarsely reticulated and bearing 

 in the center keels which are straight at the base and then diverge 

 toward the sides," but in the specimen before me it is as I have de- 

 scribed.
