of the vertex, face and antennae in striata. Both the forcwing and 

 male genitaUa of striata are also very similar to those of californica. 

 However, the two species can be separated by the following character- 

 istics: The antennae, which are banded with a brownish black portion 

 between a basal and distal yellow portion (the latter showing a sharp 

 transition) in striata, and more or less solidly brownish black in 

 californica; forewing, with pronounced raylike streaking around the 

 basal hyaline spot and the apical and inner margins in striata, the 

 location of 3d r below the pterostigma and distad of the point of 

 coalescence of Sc and Rl in striata (before and close to 2d r in cali- 

 fornica); the male parameres with the anterior margin having a more 

 shallow notch in striata, but deeper and with an additional process 

 each side of notch in californica, and the apparently tripartite hooks 

 in striata as compared with the bipartite ones of californica. C. 

 striata can be distinguished from areolaris by the antennae (brownish 

 black becoming slightly lighter toward apex in areolaris), the narrower 

 yellow portion of pterostigma in both forewing and hindwing, the 

 broader antepterostigmal streak, the radiomedial streak extended to 

 the costa, 3d r-ra short and directed slightly distad (long, oblique, 

 frequently directed basad in areolaris), and the parameres with the 

 narrower, frequently more curved arms and broader anterior notch 

 in striata. 



Climacia tenehra, new species 



Figure 20, a; Plate 2, figure 4 



Female (holotype): Head with vertex yellow, a short, transverse, 

 V-shaped spot just behind antennae not reaching lateral margins of 

 head, another minute one on posterior margin of head; face yellow; 

 maxillary palpi yellowish with terminal segments darker, labial 

 palpi yellov/ish brown; antennae with basal two segments medium 

 brown, following 17 brownish black (right antenna with 19 segments 

 remaining) ; legs yellow, meso thoracic and metathoracic coxae brown ; 

 pronotum medium brown, mesonotum and metanotum yellowish 

 brown, mesonotum blackish brown at anterior margin, mesothoracic 

 and metathoracic pleura brown; abdomen^yellowish. 



FoREwiNO (pi. 2, fig. 4): Length 5 mm., width 1.9 mm.; membrane 

 brownish mainly, blending into radiomedial streak, with some inter- 

 venational streaks below and along apical margin to Cul, large, ob- 

 liquely transverse, hyaline or yellowish area directed basally, beginning 

 and narrowest at costa covering two or three costal cross-veins in 

 center of pterostigma and broadening and extending to Cul, one 

 smaller pale area at costa before pterostigma; venation deep brown
