11. Compsocryptus turbatus (Cresson) 



Figure 368 



Cryptus turbatus Cresson, 1878, Proc. Acad. Nat. Sci. Philadelphia, vol. 30, p. 363; 

 9. Type: 9, California (Philadelphia). 



Male: Front wing 10.0 to 11.0 mm. long; temple at midheight 

 about 0.92 as long as eye, weakly convex; punctures on mesopleurum 

 and metapleurum of moderate size, strong, close, their interspaces 

 about 0.3 their diameter; propodeum as in C.jletcheri; areolet usually 

 a Uttle smaller than in C.jletcheri. 



Colored like male of C. jietcheri except that side and under side 

 of thorax is usually mostly black, with only the upper part of pro- 

 notum, subtegular ridge, and anterodorsal spot on mesopleurum fer- 

 ruginous, the metapleurum usually entirely black. Sometimes, how- 

 ever, the side and under side of the thorax is mostly ferruginous, as 

 in typical C.jletcheri. The front wing averages a little paler and more 

 distinctly banded than in male of C. jietcheri. 



Female: Front wing 7.2 to 12.0 mm. long; temple at its midheight 

 about 0.90 as long as eye, weakly convex; second flagellar segment 

 about 3.4 as long as wide; widest subapical segments of flagellum 

 about 0.70 as long as wide; thorax a little stouter than in C.jletcheri; 

 punctures of mesopleurum moderately small, sharp, dense, most of 

 their interspaces about 0.3 the diameter of the punctures; basal 

 transverse carina of propodeum absent except for a short vestige 

 behind spiracle; apical transverse carina represented laterally by a 

 rather long, moderately strong, oblique carina; areolet usually a little 

 smaller than in C. jietcheri; postpetiole a little wider, more elevated 

 medially, and more mat than in C. jietcheri; hairs on second tergite 

 as in C. jietcheri; ovipositor sheath about 0.95 as long as front wing; 

 ovipositor about 6.8 as long from nodus to apex as it is deep at nodus. 



Coloration as in female of C. jietcheri. 



This form may prove to be only subspecifically distinct from C. 

 jietcheri. A few specimens show tendencies to be intermediate. A 

 series of 3 6^, 29, from Ten Cent Lake, Steens Mts., Oreg., is particu- 

 larly indicative of intergradation between the two. We have placed 

 one male of this series under C. jietcheri, the rest under C. turbatus, 

 but the placement of all four may be arbitrary.
