PSYCHE. 



25 



This is a wood species. It is found most 

 commonly on sparsely wooded and 

 rather barren hillsides. It is almost 

 equal in size to striatum. The elytra 

 of the males are unusually ample al- 

 though not longer than the abdomen 

 and the veins of the stridulating appara- 

 tus are conspicuously large. The song 

 is louder than that of fasciatum; it con- 

 sists of two parts, the first a short 

 abrupt note which is very well repre- 

 sented by the syllable zip. the second is 

 the familiar ze-e-e which lasts about half 

 a second and is made from one to five 

 times ; the zip is not repeated. I have 

 not found it at Moline earlier than Au- 

 gust 20th. 



35. Orchelimum vulgare Hair. 

 Abundant throughout the State. I have 

 heard its note as early as the 21st of 

 July. Its song is the familiar zip-zip- 

 zip-zip, ze e-e-e-e. The staccato first 

 part is repeated about four times, usu- 

 ally about twice a second ; the ze-e-e-e 

 continues from two or three to twenty 

 or more seconds. 



36. Orchelimum glaberrimum Burm. 

 This species is very like the last and is 

 very probahh nothing more than a va- 

 riety oft. vulgare. While it seems to be 

 constantly larger and move robust it has 

 the same form of pronotum. The wings 

 are of the same length relative to the 

 elytra, the posterior femora are similar 

 in form, relatively of the same size, and 

 destitute of spines on the under side. 

 The two stripes on the disk of the pro- 

 notum are not uncommon in vulgare. I 

 have a single specimen from Effingham 

 county, which is south of the center of 

 the State. 



37. Orchelimum. longipome Scudd. 

 This species, if I have correctly deter- 

 mined it, is very like vulgare with long 

 wings. It has, however, proportionally 

 shorter legs, longer wings, with the 

 elytra considerably shorter than the 

 wings instead of equalling them as in 

 vulgare. It is much less common than 

 the last mentioned species but it is not 

 rare and is found in similar situations at 

 the same time. 



38. Orchelimum concinnum Scudd. 

 I have a number of specimens which I 

 refer to this species though the females 

 with one or two exceptions differ in 

 coloration in a marked manner from 

 typical specimens. The specimens re- 

 ferred to are almost completely infus- 

 cated with the elytra lighter or even 

 green apically and the tarsi distinctly 

 green. Rut one specimen, a male, has 

 the brown stripe extending down over 

 the face. I have captured them as early 

 as the second week in August. They 

 are partial to low, damp or swampy 

 meadows. 



39. Orchelimum nigripes Scudd. 

 This handsome species is about as com- 

 mon at Moline as vulgare. It is not at 

 all shy but is likely to be found in the ; 

 grass or shrubbery about the house. It 

 even shows a preference, I have thought, 

 for human society. During the past 

 summer an instance came under my ob- 

 servation of one keeping a place over 

 the wooden finish of a doorway for 

 more than a week. If he ate during 

 that time he must have been obliged to 

 leave his post to satisfy his hunger, and 

 he probably returned many times to the 

 place. The song is difficult to distin-
