SUBFAMILY III. COPIPIIORIN.E. 531 



Piedmont region of Georgia in March or April, will hear, during warm 

 evenings, a loud, continuous, noisy buzz, sometimes in the tallest pines and 

 oaks, or again in the weeds and low herbage of fields. This is the stridu- 

 lation of a cone-headed grasshopper known as Conoceplialus fusco-striatus 

 Redt. In this region the notes of this interesting locust together with the 

 familiar trillings of the ubiquitous field cricket, Gryllus pennsylvttnicus 

 Burm., are among the earliest insect stridulations to be heard in spring. 

 Here it is the only Conocephalus to be heard in early spring, and, judging 

 from the individuals in song during warm evenings, it is a fairly common 

 species. 



"This cone-head is strictly a nocturnal insect and stridulates most 

 freely during warm, moonlight evenings. The note is a loud, harsh, 

 snappy z-z-z-z-z-z continued for many minutes at a time. Within a few 

 feet of the stridulating insect a strong, penetrating buzzing hum is notice- 

 able, attended by almost continuous harsh, snappy, unmusical creptitations 

 which are audible for long distances, and constitute the notes usually 

 heard by the distant observer. It is somewhat difficult, especially for 

 those who have not studied insect-stridulations, to locate one of these in- 

 sects in a big field. Its powerful, penetrating notes seem to permeate the 

 herbage on every hand, frequently causing no little bewilderment in the 

 mind of one who attempts to locate the musician too carelessly. It is a 

 very shy insect and cannot readily be captured unless approached with 

 considerable care. It takes to wing readily, and flies long distances in 

 the fields or from tree to tree." 



Of the two synonyms of X. triops above noted, the name inc.r- 

 icanus Sauss. (1859, 208) has usually been given by American 

 authors to the green form, and fusco-xtr'uitiis Redt. (181)1, 399) to 

 the brown one. R. & H. (1914c, 402) first placed the latter as a 

 synonym of mexicanus and in 1915 referred both names to triops. 

 Other synonyms of triops as stated by them are Conocephalus oli- 

 tusus Burm. (1838, 705), C. dissiinilis Serv., (1839, 518), C. clis- 

 similis Harris (1862, 164), C. liebcs Scudcl. (1879a, 92), and \co- 

 conocephalus mexicanus var. tibia! is Karney (1907, 33). 



IV. HOMOROCORYPHUS Karuey, 1912, 36. (Gr., "contiguous" -(- 



"vertex" ) 



Species of large size and robust form, very similar in struc- 

 ture and general facies to those of NeoconocepTialus, with which 

 they were formerly grouped. Fastigium slightly shorter than 

 width of interocular space, its apical half convex, swollen, bluntly 

 rounded; antenna? longer than body, very slender; pronotum with 

 posterior lobe very short, lateral carimp subobsolete, hind margin 

 truncate, lateral lobes longer than deep, humeral sinus distinct 

 but shallow; tegmina variable in length; wings shorter than or 

 equal to tegmina; fore and middle femora short, subequal, armed 

 with only one or two short spines on lower, outer carinre; hind
