THE SPECIES OF THE OEDIPODINE GEXUS IIELIASTUS 

 SAUSS., OCCURRING IN THE UNITED STATES. 



I5Y SAMl'Er, II. SCIjDDF.K, CAMIilUnOE, MASS. 



Ileliaslus was ibinuled hv Sausstue in 

 1SS4 on some Mexican and Central 

 American Oedipodinae. It was first 

 recognized as occurring in the United 

 States three years ago, when I referred 

 to it two insects which had been 

 described as species of Thrincus. Both 

 of these species also occur in Mexico, 

 but were unknown to .Saussure. I can 

 now adil another and undescribed 

 species, known to me from only a 

 single locality in California, and col- 

 lected by Mr. A. P. M<.rse. .All lliese 

 northern species belong to Saussiu'e's 

 second division of the grotip in which 

 the lower posterior angle of the lateral 

 lobes is not produced into a distinct 

 process. The)- are all of a light gray 

 color, more or less irregularly spotted 

 with brown, sometimes forming brief 

 transverse markings when the insect is 

 alighted ; the wings are glazed, often 

 iridescent, and generally, at least in 

 part, weakly tinted. The males are 



considerably smaller than the females. 

 The species may be separated as fol- 

 lows : —

 two thirds as long as hind femora;
