THE NEARCTIC EVANIIDAE — TOWNES 537 



the species appears on the wing late in April ; there is a record for May 

 at Opelousas, La., three for June 15 to 23 in southern Georgia, and one 

 for June 1 at Southern Pines, N. C. At three Florida localities it was 

 taken August 10, August 18, and August 2-2. This seasonal distribu- 

 tion indicates one generation a year in the North and perhaps two in 

 Florida. 



This species occurs from the Atlantic States west to Michigan and 

 Kansas, from the Tropical and Lower Austral Zones to the warmer 

 part of the Transition Zone. It has been collected also in southern 

 Mexico. 



4. HYPTIA FEMORATA, new species 



Figure 44, d 



Femora ferruginous ; upper anterior part of mesoplcurum with 

 about three subcircuJar impressions as in -figure Jt-J;.. d. 



Forewing about 4.0 mm. long; punctures of frons somewhat con- 

 fluent in transverse rows, the rovrs separated by about 0.33 the diam- 

 eter of the punctures; seventh flagellar segment of male about 1.3 as 

 long as wide, of female about 1.1 as long as wide; median part of 

 pronotum as seen from above with a very narrow upper face; meso- 

 scutum in dorsal view about 0.74 as long as wide, its punctures sepa- 

 rated by about 0.5 their diameter; mesopleurum with an impression 

 in its median posterior corner, its ventral swelling with numerous 

 large punctures (fig. 44, d) ; under side of hind femur with rather 

 sparse coarse punctures, its impunctate area extending from near 

 its basal 0.45 to its apex; longer spur of hind tibia about 1.2 as long 

 as the shorter spur and about 0.48 as long as the hind basitarsus; first 

 tergite with moderately fine oblique striae and some scattered punc- 

 tures. 



The type is colored as follows : Black. Mandible, scape, tegula, legs 

 beyond coxae, and first tergite ferruginous, the hind tarsus and apex 

 of hind tibia somewhat infuscate. A paratype male from Uvalde, 

 Tex., is colored like the type. A paratype male from Davis Ixloun- 

 tains, Tex., is colored as the type, except that the mandible and scape 

 are fuscoferruginous, the hind tibia and tarsus are piceous, and the 

 apical part of the hind femur infuscate. A paratype female is ferru- 

 ginous with a large median basal fuscous spot on the second tergite, 

 and the apical part of the abdomen and the hind leg beyond the tro- 

 chanters weakly infuscate.
