entire present arrangement of our species of Botis is not insisted upon, 

 and is quite provisional in its character. 



66. Botis stenoi)teralis Grote, Can. Ent. x, 26. 



I have received this species from Canada (from Mr. Caulfield) and 

 Maine (Professor Fernald). An exceedingly distinct and narrow- winged 

 form, distantly recalling the European ahlutaUs, from which it differs by 

 the darker color, stouter body, narrow, even, exterior line, and black 

 discal mark on primaries above. Fore wings very dark brown, median 

 space sometimes shaded with gray; discal mark black, outer line white, 

 even , slightly rounded. Hind wings witli black terminal space, with yel- 

 lowish and fuscous basal shades and a mesial yellowish or white incom- 

 plete band continuous with exterior line on primaries. Wings beneath 

 pale reddish-ochery or whitish with common line and discal marks; 

 external line of both pair fuscous. Palpi black at the sides, whitish 

 beneath. Abdomen blackish above, annulate with white; beneath 

 whitish. Expanse, 18 mil. 



EURYCREON Led. 



1. Eurycreon chortalis Grote, Bull. B. S. N. S. 1, 89, pi. 5, fig. 13. 



New York; Massachusetts; Oregon (No. 5255, Hy. Edw.); Soda 

 Springs (Behrens). 



2. Burycreon sticticalis (Linn.). 



Illinois (Dr. Nasou). This species is European. Also found in Colo- 

 rado (Hay den). 



3. Eurycreon cereralis Zell., Beitr. 1, 517. 

 New York; Illinois; Denver (Hayden). 



4. Eurycreon anartalis Grote, Can. Ent. 10, 27. 

 California (Behrens). 



5. Eurycreon rantalis (Gueu.). 



Scopula occidentalis Pack., I. c. 



Notwithstanding the slight difference in size, the Californian speci- 

 mens seem to belong to the same species with the Texan, as indicated 

 by Zeller. Two specimens are shaded with pale ocherous, and this cir- 

 cumstance draws against the validity of communis as distinct. Lederer's 

 figure of crinitalis does not quite agree with communis, the line being 

 dentate, but Zeller's crinitalis is undoubtedly communis. I have a spe- 

 cimen which is leather-brown ! I think that rantalis and occidentalis 

 refer to fuscous forms, and crinitalis and communis to ocher forms of the 

 same ugly and variable species. Eemembering the analogy in ventralis 

 and fracturalis, such a variation cannot be considered extraordinary. 

 I did not recognize in Lederer's somewhat enlarged figure of crinitalis
