ART. 14 NEW ICHNEUMON-FLIES — CUSHMAN / 



In describing my Trichestcma I overlooked Viereck's earlier genus. 

 There can be no doubt of the sjnionymj'-. 



NEOSTRICKLANDIA HELCOSTIZOIDES (Cushman), new combination 



Tricliestcnw lielcostizoides Cushman, Proc. U. S. Nat. Mus., vol. 72, art. 13, 

 p. 0, fig. 1, 1927. 



Very similar to seiicata Viereck, but the type differs from the 

 description of ser'icata as follows: Malar space almost exactly as 

 long as basal width of mandible (not shorter as stated in original 

 description of Trichestema) ; posterior ocelli at same level as top 

 of eyes; stigma dark only along anterior margin, otherwise testa- 

 ceous; middle femur entirely ferruginous, hind femur the same ex- 

 cept at apex, where it is slightly infuscate; middle tibia at base 

 black, hind tibia entirely reddish fuscous, darker at base; median 

 carinae distinct to apical carina, defining a combined areola and 

 basal area, which broadens abruptly at the costulae; ovipositor be- 

 yond apex of abdomen less than half as long as abdomen (sheath 

 very slightly more than half as long). 



My figure is erroneous in that it shows the middle abscissa of the 

 basal carina of propodeum and the basal abscissae of the lateral 

 carinae. These abscissae are absent. 



Since the publication of my descri])tion I have received for iden- 

 tification from C. W. Johnson two females and five specimens of 

 the hitherto undescribed male, all taken by him on Nantucket Island, 

 Mass. Both females differ from the type in having the second and 

 third tergites distinctly ferruginous, the hind femur entirely and 

 the tibia except at base and apex ferruginous, and the antennae 

 23- and 24-jointed. I have been unable to discover any more signifi- 

 cant difference. 



In the male the cheeks are less strongly rounded, the malar space 

 is a little shorter than basal width of mandible, the anteniuie are 

 longer and more slender and 23- to 25-jointed, with the first joint of 

 flagellum distinctly longer than second, the white of the scutellum is 

 jnuch reduced or lacking, the propodeal spiracle shorter, the abdomen 

 more polished, the pubescence less conspicuous and on wings less 

 dense, the abdomen black with only faint reddish reflections on sec- 

 ond and third tergites, the middle and hind femora definitely black 

 at apex, the hind coxa black above at apex, the middle and hind 

 tibiae deep fuscous or black above, more reddish below, and the legs 

 more slender with apical joint of hind tarsus only as long as third 

 joint. 



ALOPHOSTERNUM, new genus 



An anomalous genus that belongs to the tribe Ichneumonini as 

 defined by Cushman and Rohwer, though disagreeing in several re- 

 spects with the description of the tribe.
