﻿NEARCTIC SPECIES OF GASTERUPTIIDAE — TOWNES 107 



wrinkled all over; temple strongly convex, fuller than in A. foxleei; 

 ovipositor sheath about 2.0 as long as the forewing. Otherwise 

 structurally similar to A. foxleei. 



Colored about as in A. foxleei except that there is no blackish triangle 

 between the eye and the lateral ocellus. 



Male: Similar to the male of A. occidentalis but the temple slightly 

 fuller, the abdomen a little more elongate, and the thorax with ful- 

 vous marking as follows: a spot on scutellum, much of propleurum, 

 and an anterior and a posterior stripe on side of pronotum. The 

 male sex is known only from the type of consors, and may be dis- 

 tinguished from that of occidentalis and oi foxleei only with care and 

 experience. 



Kieffer's name ferrugineus was proposed for the species described 

 by Scliletterer (Ann. Naturh. Mus. Wien, vol. 4, p. 537, 1889) as 

 Aulacus melleus Cresson. The description is of a female from Nevada, 

 15 mm. long and with an ovipositor 21 mm. long. Among the species 

 corresponding to the color description given, this ovipositor length 

 is found only in the true melleus of Cresson.

A female from Union City, Wash., August 11, 1908, J. C. Bradley 

 (Ithaca), has the ovipositor sheath only 1.4 as long as the forewing 

 but otherwise seems typical of the species. It may, however, belong 

 to A. occidentalis.

Figures 15, i; 16, j 



Wings strongly suffused with brown; temple moderately convex, not so 

 full as in A. occidentalis and A. melleus; top of female head ferruginous 

 with a blackish triangle pointing inward from the top of the eye (fig. 16, j). 



Forewing about 11 mm. long; as seen from above, head about 0.8 

 as long as wide; frons with very close, medium sized punctures, and 

 medially usually with some fine rugosity; top of head rather dull, with 

 fine close punctures; temple moderately convex (fig. 16, i), not as full 

 as in A. occidentalis and A. melleus; occipital carina about 0.3 as high 

 as the diameter of the first flagellar segment, slightly reflexed ; propleu- 

 rum without distinct punctures ; pronotum with some coarse wrinkling 

 and smaU, rather indistinct punctures, its anterior edge without a 

 projecting tooth; lateral lobe of mesoscutum smooth and polished
