Costal area of the elytra with three rows of areolae at its widest 

 part; membraneous pronotal margins broader, not so strongly re- 

 flected and forming an obtuse angle with the thorax 5 



5 Costal area of the elytra with two complete and a partial series of 

 areolae; nervures of elytra and membraneous pronotal margins 

 not of a uniform color, the areolae more or less iridescent, 



G. iridesccns Champ. 



Costal area of the elytra with three complete series of areolae ; 

 nervures of the elytra and membraneous pronotal margins con- 



colorous, the areolae hyaline G. albcscens n. sp. 



Gargaphia albescens spec. nov. 



Head armed with five rather short spines. Antennae slender, mod- 

 erately long, beset with a few short hairs; first segment rather short, 

 about twice the length of the second; fourth segment longer than the 

 first and second conjoined. 



Lateral membraneous pronotal margins moderately broad, angularly 

 dilated about the middle, composed of two quite regular rows of 

 areolae and in some specimens with two or three extra cells at the 

 angle. Hood moderately large. Pronotum punctate, tricarinate ; 

 carinae moderately hairy, composed of a single series of areolae. 

 Rostral sulcus deep, the rostrum almost reaching the transverse, sinu- 

 ous carina. Hood, membraneous pronotal margins, and elytra beset with 

 a few short, very fine hairs. 



Elytra moderately broad, reaching considerably beyond the apex of 

 the abdomen; costal area composed of three quite regular series of 

 areolae. Wings a little longer than the abdomen. 

 Claspers in the male large and strongly curved. 

 Length ( $ and 9 ), 3 mm.; width, 1.3 mm. 



Color. General color white. Head, thorax and abdomen black (in 

 one specimen the thorax and abdomen beneath are brownish-black). An- 

 tennae: first segment black, second and fourth (except base) seg- 

 ments blackish, third segment and base of fourth dirty white. Legs 

 dirty white, the tips of tarsi and nails embrowned. Nervures of 

 hood, membraneous pronotal margins, posterior triangular process of 

 pronotum, and elytra white ; areolae hyaline. Nervures of carinae 

 white, except a few of the transverse nervures embrowned. Wings 

 iridescent. Bucculae, rostral sulcus, and transverse carina broadly 

 margined with white. Claspers in the male embrowned. 



Four specimens, taken at Sacramento, California, by Mr. D. 

 J. Condit. Type in my collection : paratypc in the collection of 

 Prof. J. G. Sanders. This species can readily be separated 

 from allied forms by the characters given in the key. It is 

 most closely related to angulata and iridescens.
