is of the same shape and is blackened beneath as in the Florida speci- 

 men. Measurements of the male are as follows : 



Length of body 28 mm. 



Length of fastigium beyond eyes 2.5 mm. 



Length of pronotum 7 mm. 



Greatest caudal width of disk of pronotum 4 mm. 



Length of tegmen 33 mm. 



Length of caudal femur , 18 mm. 



When males from the south are collected they will probably be found 

 to average somewhat larger. 



While at Ernia, Cape May Co., N. J., in August, 1910, a few males 

 of what appeared at the time to be Conocephaliis robustus were col- 

 lected in the meadow bordering Bradley's Run. When these were 

 pinned in line and compared with undoubted robustus from Fire 

 Island, N. Y., Staten Island, etc., it was seen that while they greatly 

 resembled that species, the fastigium was more blunt in the specimens 

 from Erma. In August, 1912, additional material was collected and 

 the song listened to with care. While it consisted of the same con- 

 tinuous whirr as in robustus, it was not nearly so ear-splitting. .There 

 were no robustus to be heard about Erma or Cold Spring, but the fol- 

 lowing evening the colony at Chatsworth, N. J., was visited, so a near 

 comparison in point of time was rhade. In the collection of the author 

 there are two additional specimens like those from Erma ; one collected 

 at Virginia Beach, Va., July 20 (Geo. P. Engelhardt), and one from 

 Herndon, Va., August, 191 1 (H. G. Barber). The Erma, N. J., and 

 Virginia insects resemble Conocephaliis crepitans Scudder more nearly 

 than any other described species, but seem to average a little less 

 robust than examples of that insect from Kansas and Nebraska. The 

 type of crepitans came from Texas. The Atlantic States or eastern 

 crepitans appears to bear about the same relation to western crepitans 

 as does lyristes to nebrascensis and ensiger to attenuatus. These com- 

 parisons may be more superficial than real, as I am unacquainted with 

 the habits and songs of nebrascensis and attenuatus. There is no 

 doubt, however, that we have in Virginia and New Jersey an insect 

 that has been heretofore overlooked, and which for the time being 

 may be considered as crepitans.
