are thick and horny, and are termed elytra. In water-bugs and 

 others, they are similar to elytra, but the apical part is membra- 

 nous, hence their name of hemelytra. In grasshoppers and katy- 

 dids they are leathery, or parchment-like, and are called tegmina. 

 Many insects, even of those groups which, as a general rule, 

 undergo a complete transformation, are wingless. Sometimes 

 only the front wings are present; the hind wings are then usually 

 represented by a pair of small club-shaped organs the halteres, 

 balancers, or poisers as in the common house-fly. Rarely the 

 hind wings only are present, in which case the front wings are 

 represented by organs similar to the halteres, but distinguished 

 from them as pseudo -halteres. P. P. C.

CICINDELID> OF A SEASON. 



BY CHAS. LIEBECK. 



This has been the most successful season for Cicindelce that 

 has occurred during my experience in Coleoptera collecting. 

 Of nineteen species and varieties occurring in eastern Pennnsyl- 

 vania and southern New Jersey, fourteen have been taken by me 

 this season. 



The species follow in order as they are listed, with some refer- 

 ence to their occurrence during former years. 



Tetracha virginica Linn. Nocturnal in habits, a few specimens 

 being taken in open fields under boards and fence rails, middle 

 of July, at Abington, Pa. 



Cicindela unipunctata Fab. Reported as occurring at Atco 

 and Woodstown, N. J. One of the species not taken this season. 



C. modesta Dej. Not taken as abundantly this season as in 

 previous years, but scattered individuals taken in May, June and 

 July, in all sections df southern New Jersey, in which any col- 

 lecting was done. Two days in May, 1887, over one hundred 

 specimens were taken in a space, not more than sixty feet square, 

 below Gloucester, N. J. A second brood appears in September. 



C. 6-guttata Fab. Twelve or fifteen specimens were taken 

 under the bark of fallen trees along the banks of Cobb's Creek, 

 Philadelphia, early in April, and a number on the wing the first 

 week in May. Some have also been taken in July. 



C. patruela Dej. Occurs at Lancaster, Pa.; not taken this 

 season.
