The single specimen taken was collected at night with the 

 aid of a lantern, stridulating loudly on a low green bush. 

 Even when approached it did not cease its stridulation, but 



kept up a loud and constant zick, zick, zick, zick, much 



like our eastern Scudderia but far louder. Other individuals 

 were heard stridulating loudly during the night until just be- 

 fore dawn. 



In endeavoring to capture other specimens during the eve- 

 ning one was located in a high oak tree, another about twelve 

 feet from the ground in a dense bush, another in a tangle of 

 vines near the ground and others, including the specimen 

 captured, in low green bushes on the mountain side. All 

 collecting was done after dark which made it very difficult 

 to locate the specimens, and, although they did not move until 

 approached very closely, they usually ceased their song when 

 disturbed. One which I succeeded in almost grasping es- 

 caped by tumbling down into the thick weeds under its perch. 



New Scarabaeidae. 



BY H. C. FALL. 



The present article was primarily designed to make known 

 an interesting new species of Thyce discovered by Mr. G. TT. 

 Field, of San Diego, in the summer of 1906. The opportun- 

 ity is taken, however, to add descriptions of two species of 

 Lachnosterna and a Polyphylhi which appear to be without 

 names. The relation of each of these to previously described 

 forms is easily made known, and there is therefore little use 

 in awaiting monographic treatment of their genera of which 

 there is either little need or small prospect in the near fu- 

 ture.
