apex and the fourth darker brown; frontal spines yellow. Median line 

 of hood, anterior two-thirds of median carina, and antero-lateral margins 

 of paranota dark brown; reticulate portions of pronotum otherwise 

 yellowish. Costal and most of sutural areas of hemielytra with hyaline, 

 iridescent areoles, the veinlets largely yellow, a few brown; subcostal 

 area, discoidal area, and two rows of sutural areoles next to discoidal 

 area, opaque white; apical one-third of discoidal area largely occupied by a 

 depressed, triangular, dark brown spot, on each hemielytron. Legs 

 yellowish. 



Frontal spines stout, crowded, about one-half as long as the first an- 

 tennal segment; basal spines vestigial. Pronotum sparsely hairy; the 

 carinae low, uniseriate; hood about one-half longer than broad (14-10), 

 well inflated, almost as high as median carina; paranota moderately 

 reflexed, acutely angulate, at most three areoles wide, anterior margins 

 slightly concave, posterior margins convexly rounded and nearly vertical 

 above bases of hemielytra; width across paranota almost equal to entire 

 length of pronotum (48-50). Costal area of hemielytra triseriate for a 

 short distance (about equal to three aeroles) at widest part, otherwise 

 biseriate; subcostal area biseriate; discoidal area one-half as long as 

 hemielytra, about four areoles wide at most. 



Length 2.7 mm.; width 1.2 mm. 



Holotype 9 , Biscayne Bay, Florida (A. T. Slosson) in Mrs. 

 Slosson's collection. 



This species is especially distinguished by the hemielytral 

 markings; it runs in Gibson's key 1 to iridescens Champion, 

 from which it differs in the structure of the head spines, 

 width of pronotum, and most other details, in addition to 

 coloration. This is the first species of the genus to be re- 

 corded from Florida. I am indebted to my friend Gibson's 

 kindness for the opportunity of examining certain related 

 species not represented in my own collection. 



Corythucha cyrta Parshley. 2 



Having had occasion recently to determine a good many 

 specimens belonging to the genus Corythucha, I am more than 

 ever impressed with the difficulties involved in the study of 

 the group. Gibson's review r is a most creditable pioneer 

 work, but there are certain aspects of the subject which re-
