A ROTES MCINUS Cresson. 



Arotes mdnus CnBasotf , Trans. Amer. Ent. Soc, vol. 2, 1869, p. 260. 

 Arotes venustus Chesson, Trans. Amer. Ent. Soc, vol. 2, 1869, p. 260. 

 Arotes superbus Provancher, Nat. Can., vol. 6, 1874, p. 81, 



Type oivicinus, one male, Cat. No. 1432, Academy of Natural Sci- 

 ences, Philadelphia. Type of venustus, two females (one type). Cat. No. 

 1433, Academy of Natural Sciences, Philadelphia. Type of superbus, 

 not located, but probably in Public Museum, Quebec, unlabeled, under 

 the name vicinus. 



In describing vicinus Cresson did not specify the sex or number of 

 specimens, but it is certain that he had only the male, and in the col- 

 lection of the Academy of Natural Sciences in Philadelphia there is 

 one male which was made lectotype by Cresson. This male is the 

 opposite sex of the species described as venustus. The male originally 

 associated with venustus represents a different species and should be 

 known as occiputalis, a name suggested by Cresson. 



Robust ; ovipositor distinctly longer than the abdomen, but shorter 

 than thorax and abdomen ; recurrent usually interstitial, but in some 

 specimens antefurcal; hind coxae rufous, with bases and apices black 

 or black with rufous spots; wings subhyaline with the usual apical 

 spot. 



Distribution. — Massachusetts (Cresson) ; Quebec, Canada (Pro- 

 vancher); New York; Munsing, Michigan (H. B. Morris); Whitefish 

 Point, Michigan (A. W. Andrews) ; Inglenook, Pennsylvania (Craig- 

 head) ; Brettell Mills, South Dakota (Hopkins) ; Falls Church, Virginia 

 (Kirk). 



Hosts. — Reared as a parasite of Leptura vittata by F. C. Craighead 

 and from a pine stump containing Leptura ruhrica and L. vagans by 

 H. B. Kirk. 



AROTES OCCIPUTALIS Cresson. 



Arotes occiputalis Cresson, Trans. Amer. Ent. Soc, vol. 2, 1869, p. 260. 

 Arotes apicatus Davis, Trans. Amer. Ent. Soc, vol. 24, 1879, p. 366. 



Type of occiputalis, two males (one type). Cat. No. 4001, Academy 

 Natural Sciences, Philadelphia. Type of apicatus, one female. Cat. 

 No. 164, Academy Natural Sciences, Philadelphia. 



In describing venustus Cresson expressed a doubt as to the correct 

 association of the male and suggested that the male he described was 

 possibly "a distinct species, in which case it may be named occipu- 

 talis.^' The name occiputalis has therefore been omitted from most 

 of the catalogues. The female described by Davis as apicatus is 

 undoubtedly the female of occiputalis.
