Parabates inspiratus n. sp. 



Body black with the knees, the tibiae, and the tarsi infuscated ; 

 the antennal furrows deep and broad, above and below, interrupted on 

 the middle of the front, the lower ends connectini^ with the antennal 

 fovea, transversely divided by a ridge just above the base of the 

 antennae, the portion above the ridge punctiform, deep and broad, 

 the vertical portion deep, extending from the occiput to beyond the 

 lateral ocelli, much longer than wide, the interocellar furrow distinct; 

 the ocellar basin depressed around the median ocellus, with a broad 

 furrow extending from this basin to the interocellar furrow; the median 

 fovea broad, rather shallow, narrower than the space between the 

 antennae ; the supraclypeal area convex and prominent ; the antennae 

 slender, the first and second segments globular, subequal in length, 

 together subequal in length to the third, the third twice as long as the 

 fourth, the fourth and following segments subequal in length, all the 

 segments densely hairy; the wings slightly infuscated, the veins, includ- 

 ing the costa and the stigma, brownish, not with a fuscous band be- 

 tween the tip of the third anal vein and the base of the cell 1st A-f 

 2nd. 2nd A; the posterior metatarsus subequal in length to the four 

 following segments ; the saw-guides convex above and below, rounded 

 at apex below and forming an evenly rounded point above, the entire 

 surface coarsely and closely punctured, covered with fine, short setae. 

 Length 4 mm.
