Jan., 1922 synopsis of the genus stenocranus 73 



spots on the commisural margin near apex, and a wide part of the costa 

 somewhat wine-colored-hyaHne, transverse apical veins of this part 

 fuscous and margined with fuscous. Head moderately prominent. 

 Female. Length with tegm. 5 mm. 



Country: South CaroHna and Pennsylvania. (Mus. Holm.). 



Stenocranus feiti Van D. 

 (1910 Trans. Am. Ent. Soc, xxxvi, p. 88). 



Closely allied to dorsalis, differing principally in having the 

 apex of the vertex broader and more rounded, the front pro- 

 portionately broader and shorter, and the pygofer of female is 

 much broader apically and almost pyriform. 



Head decidedly narrower than the pronottmi. Vertex produced 

 about one-third its length beyond the eyes, carinas distinct. Front long 

 and narrow, sides subparallel, narrowed towards base tricarinate. 

 Antennas with second segment about three times as long as the first; 

 seta short. Pronotum as long as the vertex, tricarinate, the lateral 

 carince attaining the hind margin. Scutellum short, about one and a 

 half times as long as the pronotum, tricarinate. Elytra comparatively 

 very short and broad and are held in a more or less roof-shaped position. 

 Calcar slender. 



General color a soiled yellowish-testaceous with the carinse a little 

 paler and the dorsum marked with a whitish vitta from near the front 

 of the vertex to the tip of the scutellum, which is continued by the pale 

 commisural nervure of the closed elytra. Front with the intra-carinal 

 spaces pale brown or almost concolorous. Basal segment of antennae 

 with a black mark inferiorly, a similar mark on the cheek below the 

 ocellus, and the antennal socket has a distinct black marginal spot 

 anteriorly. Venter in the male black with the segments edged with 

 orange. Elytra in the female pale yellowish hyaline with the nervures 

 a little darker, sometimes becoming almost black on the clavus and 

 inner margin of corium; the second apical nervure and the apex of the 

 others deep black. In the male the nervures are almost entirely 

 blackish fuscous, and the black of the second apical ner\^ure is spread 

 over the adjoining areole. Legs lineated with fuscous. 



Female ovipositor sheath broadest apically, pyriform, fuscous, 

 foliaceous, closely appressed to and covering the genital segment; anal 

 style large and fuscous. 



Male pygofer light brown in color, base fuscous, large, with ventral 

 margin roundingly excavated; genital styles reddish-brown, large at 

 base and pointed on either side about middle, then roundingly and 

 abruptly emarginate, narrowed and drawn out to an acute tip; anal 

 tube with a sharp, reddish-brown tooth each side. 



Length of body 3 mm. ; length to tip of elytra, 4-5 mm.
