and the saw-guides; antennae not thickened at middle, the first and 

 second segments globular, subequal in length, together five-sixths the 

 length of the third, the third as long as the fourth and fifth together, 

 the fourth slightly longer than the fifth, the fifth and sixth subequal 

 and each sHghtly longer than the seventh, eighth and ninth, which 

 are subequal, the ninth with parallel sides and a bluntly rounded 

 point; the clypeal foveae deep and prominent; the supraclypeal* area 

 slightly convex and not prominent; the antennal furrows deep, promi- 

 nent, extending from the clypeal fovea to the occiput, and almost 

 straight; the median fovea an inverted wedge-shaped depression, long- 

 er than broad; the postocullar area convex, well separated; the inter- 

 ocellar furrow distinct, continuous, straight; the ocellar basin fan- 

 shaped, connected with the interocellar furrow; the posterior meta- 

 tarsus shorter than all the following segments together; the second 

 and third segments of the tarsi subequal ; the front wings with the free 

 part of R4 twice as long as the free part of Rj ; the stigma convex below, 

 about three times as long as broad, angled at the point of attachment 

 of the radial cross-vein; the veins, including the costa and the stigma, 

 luteous; the saw-guides moderately robust, truncately rounded, and 

 somewhat pointed at the upper apical angle. Length 4 mm. 



Habitat. — Las Cruces, New Mexico. Described from two 

 females received from Prof. T. D. A. Cockerell. 



The male according to Marlatt does not differ except in 

 ha\-ing a greater percentage of white or brownish white on the 

 body. 



Parabates n. gen. 



Head transverse, front not as broad as high; the inner mar- 

 gin of the eyes uniformly convex, the eyes distinctly converging 

 below; the antennal furrows obsolete except adjacent to the 

 antennal foveae and behind the lateral ocelli ; the clypeus squarely 

 truncate, distinctly more than half as wide at apex as at base; 

 the antennae long and filiform, the second segment as long as 

 the first, longer than broad, as wide as the first segment, not 

 annular, the first and second segments together as long as or 

 longer than the third; the front wings with the free part of R^ 

 and the radial cross-vein not interstitial and inclined at the 

 same angle; the free part of M4-I-CU1 received at the middle of 

 the cell ist A -h 2nd 2nd A; media strongly angular at the point of 

 separation of Mi+o and M3+4; the radial sector strongly bowed at 

 base. Type Parabates histrioniciis n. sp. 



*Marlatt in his monograph of the Nematinae uses the term hypoclypeal 

 plate for this area and the writer has referred to it thus far as the hypoclypeal 

 area. The word hypoclypeal is a misnomer, meaning below instead of above 

 the clypeus, it is also a hybrid in origin and should be discarded.
