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 oi 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 l^ind 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 

 fepresented by organs similar to the halteres, but distinguished 

 from them 3.% pseudo-halteres. P. P. C. 



CICINDELID>E OF A SEASON. 



BY CHAS. LIEBECK. 



This has been the most successful season for Cichide/ce 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 xnrginica Linn. — Nocturnal in habits, a few specimens 

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

 of July, at Abington, Pa. 



Cicindela unipundata 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 of 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-g7ittata 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. 

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

 season.
