THEODORE H. FRISON 7 



lias only one closed cell in the front wing, wliereas the genus 

 Evania has seven such cells. The figure also shows another 

 vein, placed as an anal vein. This is very probably only a 

 fold or furrow in the anal region; in which case crassa belongs 

 to the genus Hyptia. If not a fold or furrow, the illustration 

 depicts a type of wing not noted or found elsewhere in this 

 subfamily. 



One specinien, a paratypc of H. spijiifera, was dissected in 

 order to determine the sex. This specimen was a male. As 

 the dissected specimen agreed in all details with the other two, 

 I assume they are also males. The antennae of H. jucunda re- 

 mind one of those of the females of other related genera, and so I 

 have doul)tfully considered tliis species as a female. Without 

 dissecting, I judge two other species of Hyptia dcscril)ed here 

 to be males. 



Key to Species of Hyptia here dcscnhed 



1. Hind tibia with distinct, long, prominent si)inulae; head and thorax entire- 



ly or partially ferruginous or fulvous 2 



Hind tibia without prominent spinulae; head and thorax entirely black. 



jucunda new sjiecies 



2. Occipital orbits with a douljle row of shallow punctures adjacent to the 



eye; dorsum of petiole with rather coarse punctures interrupting the 



longitudinal striae spinif era new species 



Occipital orbits with but a single row of shallow piuicturcs adjacent to 

 the eye; dorsum of petiole with distinct, uninterrupted, longitudinal 

 carinae 3 



3. Metunapleura and petiole black; truncature with a small, medial, polished 



area neglecta new species 



Metunapleura entirely ferruginous, petiole with a reddish suffusion; trun- 

 cature with reticulations extending over the entire surface. 



fraudulenta new species 



Hyptia jucunda new species 



Female. Length, .5 mm. 



Head, thorax, propodeum, pedicel, abdomen and hind legs, i)la(k. Fla- 

 gelkir segments distad of first segment greyish-black. Mandibles, scape, 

 pedicel, proximal half cf first flagellar segment, tegulae, fere and middle legs, 

 fulvous. 



Head bek)w antennae with a small cresrcntic area of closely-placed, shallow, 

 irregular punctures, ventrad of this area the pimcttires are coarser, fewer 

 and often confluent; face separated from malar space by a smooth, elevated, 

 inipunctate carina; occipital orbits over twice as wide below as above, with 

 a single row of small punctures al)out mifl-way between row of pimctures
