NEW GENERA AXD SPECIES OF BEACOXIDAE. 59 



eniarginate, antennae 62-segmented, long and slender, black 

 except segments 1 and 2 which are also stouter, and hairy; 

 face broad, slightly bulged, closely and distinctly punctate and 

 hairy, faintly carinated above, clypeus distinct, cheeks narrow, 

 mandibles stout, tips black, bidentate, a distinct slit-shaped 

 mouth opening, palpi slender, 6 and 4-segmented respectively. 

 Thorax as wide as the head and deeper than wide, pronotum 

 inconspicuous but the pleurae well developed, notauli con- 

 spicuous, fairly deep, mesopleurae with a short groove on 

 posterior margin and hairy in parts, disc of scutellum angu- 

 late, octafoveate in front, metanotum convex with a median 

 carina which bifurcates behind forming a small semilunar 

 areola, pleurae hairy, the groove separating notum and pleura 

 wide and steep, the circular spiracle at about the middle. Ab- 

 domen subsessile, short ovate, not longer than the thorax and 

 depressed, 1st segment about as long as its width behind, with 

 a broad keel, the minute spiracles are slightly elevated and 

 median in position, following segments all transverse and 

 nearly subequal, all finely and sparsely punctured and hairy 

 above and below, ovipositor exserted about one half the length 

 of the abdomen, the legs long, thin and hairy. The wings 

 hyaline, stigma fairly broad, radius arising at the middle, 1st 

 abscissa less than half the 2nd, which is longer than the fusi- 

 form 1st cubital cross-vein, 2nd cubital cell narrower out- 

 wardly than at base, the 1st cubital and the 1st discoidal cells 

 are separate and the latter is short petiolate. almost sessile, 

 the transverse medial nervure is postfurcal, the discoidal ner- 

 vure beyond is greatly thickened, the recurrent nervure is 

 strongly curved and at the end where it merges with the cubital 

 is strongly incrassate, a slight suffusion at end of the anal 

 nervure. In the hind wings the radius is obliterated and the 

 submedian cell is about half the length of the median. 



The $ has the abdomen concolorous instead of black.
