Vol. xxiii] ENTOMOLOGICAL NEWS 39I 



This is the first species of the genus to be recorded from 

 the Western Hemisphere, but seems to be a true Telostylus 

 and the genus may be further characterized as follows : 



Elongate, slender; head produced anteriorly, being much 

 longer than high : eyes roundish ; front and oral margin nearly 

 parallel ; occiput and face produced beyond orbits : inner and 

 outer vertical, reclinate or erect, decussating ocellar. two front- 

 als and one buccal bristles present, all small ; a polished callous- 

 like swelling at base of each antennae ; palpi lanceolate, not 

 constricted basally. Antennae elongate, porrect ; first joint 

 not longer than third ; second with inner margin produced 

 thorn-like along side of third joint; latter long, conical, with 

 a long thickly pubescent arista at its apex, the thick pubes- 

 cence giving it a solid appearance basally. (fig. 2). 



Thorax elongate, conically developed anteriorly ; propleurae 

 strongly developed in front of fore coxae, causing the latter 

 to be forced nearer the middle pair; the latter and posterior 

 pair close together, the metapleura with a rounded callous-like 

 swelling. Scutellum obtusely triangular, i pair prescutellar, 

 I supra-alar. 2 notopleurals, 2 scutellar bristles, present, all 

 short, no bristles or hairs on pteropleura. Abdominal seg- 

 ments sub-equal, slightly diminishing apically ; ovipositor nor- 

 mal. Legs slender ; femora much stouter, with stout but short 

 spines beneath ; posterior coxae with a lateral subapical bristle. 

 Wings normal. 



The three known species may be separated as follows : 



South American species ; mesonotum brown with a median pale stripe 

 and a yellow stripe between humeri and wing, .vittatus n. sp. 

 East Indian species ; mesonotum pale with black spot behind humeri. 

 Scutellum pale with brown side spots ; a black spot above each 



wing maccus O. S. 



Scutellum entirely pale; no spot above wings. . .binotatus Big.
