or THE ISLAND OP ST. VINCENT. 107 



referable to this species with some slight doubt, since faulty 

 mounting obscures some of the characters. The types were 

 reared in Florida from the larvae of Flatynota rostrana, "Walker. 



Elachistus, Spinola. 



ElACHISTITS CAtTDATirS, sp. n. 



$ . Length 1 millim. ; expanse 2 millim. Eront very deeply 

 impressed; eyes naked; mesoseutum very deeply and coarsely 

 pitted; mesoscutellum smooth ; metanotum with undivided median 

 longitudinal carina, which is not specially elevated in front ; 

 lower border of front and hind femora with a fringe of rather 

 long delicate hairs ; ovipositor extruded to a distance which is 

 nearly as long as entire abdomen ; abdomen flattened, oval, 

 rather strongly incised behind, flattened above. Colour black, 

 shining ; face honey-yellow, occiput with black centre and yel- 

 lowish border to eyes ; all coxse honey-yellow ; other joints of 

 legs light yellow-brown. Abdomen piceous ; wings hyaline, 

 veins translucent, colourless. 



Described from one female specimen. St. Vincent. 



This will evidently form a new genus. I know of no other 

 species in the subfamily Elachistinre which has a similar ovipositor, 

 and there are probably other distinguishing characters. The 

 single specimen at hand, however, lacks antennae, and is other- 

 wise in poor condition for generic description. 



Elachisttts scutellatus, sp. n. 



$ . Length 1'5 millim. ; expanse 3 millim. Eacial depression 

 broad, reaching nearly to margin of eyes, sharply defined just 

 below insertion of antennae by an acute transverse ridge ; eyes 

 hairy ; ocelli forming slightly curved line ; head and face slightly 

 rugose ; head with sparse long hairs ; pronotum and meso- 

 seutum slightly shagreened, with sparse large punctures ; meso- 

 scutellum with no indication of a median furrow, faintly longi- 

 tudinally and quite regularly striate ; median longitudinal carina 

 of the metanotum broad, not high, not acute, divided into the 

 two elements of the anterior transverse ridge ; nucha narrow, 

 surrounded by an elevated margin continuous with the median 

 longitudinal carina ; metanotal alae separated by slight but dis- 

 tinct oblique furrows converging posteriorly ; abdomen flattened, 

 oval, not incised ; mesonotal bristles long. Colour black, sub- 

 opaque ; abdomen with a basal honey-yellow spot above and 

 below ; antennal scape and pedicel and all legs, except hind coxae
