PSYCHE. 



(December 189S. 



writer found another specimen six miles 

 west of Lawrence in a strawberry patcli 

 on a high hill overlooking Lake View. 

 In a letter upon this subject, Mr. S. 

 H. Scudder gives references to the cap- 

 ture of Dissosteira longipennis., in Texas 

 (Boll), in Nebraska, "entire state" 

 (Bruner), in extreme western Kansas 

 (Osborn) , Barber Co., Kansas (Bruner) . 

 He says farther: "I have 34 refer- 



ences to it in literature, but in none do 

 I find a reference to its capture as far 

 east as Lawrence," and thinks it improb- 

 able that it has been reported as taken 

 this far east. 



These notes are given in evidence of 

 what may be considered an eastward 

 tendency in the geographical range of 

 this insect.

A very variable species. In the fresh 

 state its general coloring — a peculiar 

 olive with blackish markings — is very 

 appreciable and of service in recogni- 

 zing it, though the long-winged female 

 is liable to be mistaken for femur-ru- 



brum. While tegmina of every length 

 between the extremes given are to be 

 found, most of the specimens observed 

 fall into two series, a short- and a long- 

 winged. In the former the tegmina 

 usually fall about 2 mm. short of the 

 end of the hind femora ; in the latter 

 pass them by 2 or 3 mm.; — the names 

 Junius and scandens respectively have 

 been applied to these by Scudder. Of 

 the specimens now in my collection (a 

 number having been disposed of through 

 exchanges) about one-eighth of the 

 females and two-thirds of the males are 

 long-winged {scandens) . The long- 

 winged form seems to be more preva- 

 lent in high latitudes and at high ele- 

 vations. In point of size also the 

 species varies much according to local- 

 ity, specimens from Winchendon, Mass., 

 (800-1200 ft.) being noticeably larger 

 than those from the summit of Mt.
