the ? out, as (.loes Weidemcyer p. 27, svhii gives it tlie locality "U. S. ". 

 W. H. Edw. in all iiis catalogues leaves out the ?, and in the one of 

 1877 adds to locality "(Prob. Brit. Am.)''. All these were made without 

 a personal knowledge of the insect. Strecker in his catalogue, 1878, p. 

 151, (prt)bably under the suggestion of Hewitson), expresses his convict- 

 ion that the species is not North American but Soutn American. Kirby, 

 Cat. of the Diur. Lep. in CJoll. W. C. Hewitson 1879, p. 130, gives 

 without any e.xpression of doubt, locality '"South America''. Wether this 

 is based on the previous knowledge of Mr. Hewitson, or on evidence 

 gained by Mr. Butler l)y new materia! I do not know; but in view of it, 

 the locality originally surmised must have been an error, and in the 

 present state of the case, the species must be dropped from our lists. 

 No authenticated specimen has ever been taken in North America so far 

 as 1 can learn. 



The most of our species of Erebia have been named on very limited 

 material, not always in the best condition. It is probable a large gather- 

 ing of material vvill very greatly modify our present list.

STYLOPIDiE. 



The species of this family are very rare indeed in American collect- 

 ions, but seem more common in Europe. In an old number of the 

 "journal of Microscopy and Natural Science" is an article on the subject 

 from which I cjuote: "On another occasion saw about 20 iiying, but they 

 were so high from the ground he could only capture half a dozen. The 

 little animals are exceedingly graceful in their flight, taking long sweeps 

 as if carried along by a gentle breeze, and occasional! yhovering at a few 

 inches from the ground". They are in Europe parasitic on Andrena, 

 which is a very early species, flying in April. The (^(^ are said to em- 

 erge from the pupse early in the morning — 9 to 11 a.m. 



Our species, Xenos Peckii is parasitic on Polistes and I have very 

 often seen the head of the pupa projecting between the segments of the 

 abdomen of our common species. In the "classification" it is stated that 

 the head of the pupa case of the (^ is convex; that of of the 9 '^'^'^' Spe- 

 cimens o'i Polistes found with a ^ pupa might be confined with proper 

 food until the parasite emerges. Suppose some of our Collectors turn 

 their attention to Stylops this s()ring! J. B. S.
