SPONGILLA-FLIES — PARFIN AND GURNEY 491 



westward to Minnesota, Kansas, Oklahoma and eastern Texas. 

 In the western part of the United States, it is replaced by californica 

 in California and Oregon, and by chapini in New Mexico and central 

 Texas. The specimens referred to areolaris from Texas (Columbus, 

 Schwarz; unspecified locality, Belfrage) by McClendon (1906, p. 171), 

 and from New Mexico (Eddy County) and Texas (Sutton County, 

 Victoria) by Carpenter (1940, p. 256) were examined and found to 

 be chapini; those referred to this species from the Deschutes River, 

 near "Richmond," Oreg., by Carpenter (1942, p. 50) were apparently 

 californica. It is likely that the "pair from Bosque County, Texas, 

 taken by Mr. Belfrage (in August)," mentioned by McLachlan in 

 his original description of the genus Climacia, but not examined, are 

 also chapini. 



Specimens which have been recorded as this species, but which 

 were not examined, include those from Michigan (East Lansing and 

 Silver City), Pennsylvania, Vermont (Carpenter, 1940, p. 256), 

 Maine (Robinson Mountain, Mount Desert Region) (Procter, 1946, 

 p. 42); and Valle de Mexico, Lago de Xochimilco (Navds, 1928, 

 p. 319). 



In addition to the distinctive male genitalia, a notable character of 

 areolaris that separates this species from other species of Climacia 

 is the 3d m, which is usually long, slightly sinuous, and sharply 

 obliquely directed basad, making cell 2d MA the shape of an inverted 

 trapezoid. C. areolaris is further distinguished from califoriiica, which 

 closely resembles it in the forewing, by the comparatively long cell 

 2d Rl, which is more than three times as long as wide; the broader 

 pale area (covering seven to eight costal cross-veins) in the pterostig- 

 ma of the forewing and hindwing; the color of the head; the lack of a 

 basal radiomedial streak in the hindwing and the less extensive 

 spotting in general in the forewing and hindwing; the greater number 

 of branches to Cul in forewing and hindwing; and the genitalia. It is 

 quite distinct from chapini also, which has the long crescent-shaped 

 basal radiomedial streak and a different type of genitalia. From 

 striata (Panama), which also has a sunilar forewing, areolaris can be 

 segregated by the broader pale area of the pterostigma in the forewing 

 and hindwing, the less pronounced dark spotting, the antennae which 

 are not banded, and the female genitalia.
