I have been mucri in doubt concerning the proper location of this 

 species. It is a winged female with the basal nervure rather more 

 strongly curved than is usual among the Hemitelini, thus approaching 

 the tribe Pezomachini, all of which are wingless in the female sex. 

 The thick legs are also anomalous, but their appearance is quite likely 

 due in part to compression in the stony matrix. 



Hemiteles veternus, sp. nov. (Fig. 30.) 



Probably a male. 



Length about 5-6 mm. 

 as wide as

 nov. Type. 



veternus, sp. 



Head transverse, about twice 

 thick, black. Antennae not 

 preserved. Thorax elongate, twice as long 

 as wide; smooth, not punctate. Scutellum 

 elevated, triangularly narrowed behind. 

 Metathorax completely areolated ; median 

 areola elongate, pentagonal ; petiolar area 

 short and broad; three lateral areas and 

 one pleural one that may possibly be 

 divided. Abdominal petiole long, in length 

 equal to the metathorax and scutellum 

 together, gradually widened, its spiracles 

 near the tip. Following abdominal seg- 

 ments not or barely visible, probably 

 lighter in color. Legs slender, more or 

 less pale. Wings hyaline, the veins and 

 stigma pale fuscous. Stigma subtriangu- 

 lar, marginal cell barely three times as 

 long as high ; areolet open, pentangular in 

 position; discocubital vein very strongly 

 bent toward the base, its base almost 

 perpendicular to its tip. Second discoidal 

 cell closed, submedian cell very slightly 

 longer than the median.

Cryptus delineatus, sp. nov. (Fig. 31.)
