Jan., 1922 synopsis of the genus stenocranus 79 



Male pygofer medium in size, excavated into a large median spur 

 and two longer lateral ones ; anal tube with a long, sharp median process 

 on ventral margin; genital styles rather long, larger at base, narrowing 

 in middle, much enlarged, retorsed, and cut off distad, very pale in 

 color; aedeagus of dark fuscous chitin, composed of three parts, the 

 ventral one rather stout, sharp, and barbed, the middle one thorn-like, 

 very long and sharp, the upper one short and stout with a pair of curved 

 hooks at tip. 



Length to tip of elytron, male, 4 mm. ; female, 4.75 mm. 



The male is similar to the female in coloration and markings, but is 

 smaller. 



Described from a series of nineteen males and fourteen 

 females, taken sweeping at swamp edge, Los Amates, Guate- 

 mala, Jan. 17, 1905, by Prof. J. S. Hine, after whom I name 

 the species. 



Holotype and allotype in collection of Prof. Herbert Osborn 

 as well as those paratypes not otherwise designated. Paratypes 

 in U. S. National Museum and in the collections of Z. P. Metcalf 

 and the author. 



Stenocranus angiistus Crawford. 

 (1914 Proc. U. S. Natl. Mus., xlvi, p. 589). 



As I have not seen the original type specimen I am including 

 here the original description. 



"Length of body, 3.1 mm.; width of vertex, 0.20; width of frons, 

 0.22; antennee, I, 0.05; II, 0.22. General color brown or dark 

 brown, dorstun with conspicuous white vitta; frons black between 

 carinse; femora striped black; elytra mostly dark brown except outer 

 anteapical and costal cell and small part of membrane light. 



Vertex aboiit as long as in dorsalis, projecting about one-third its 

 length before eyes, about twice as long as broad; frons one-third as 

 broad as long, slightly narrowed at ocelli. 



Thorax slender; prothorax not much broader than head; scutellum 

 long. Calcar slender. Elytra long and very slender. 



Male genitalia somewhat similar to dorsalis; styles more slender and 

 delicate, very acute and slender distad. 



Described from one male, taken at Belize, British Honduras, 

 by J. D. Johnson. This species is similar in many respects to 

 the northern 6". dorsalis.
