The writer found confluens breeding on Polymnia uvcdalia 

 in Missouri and the species doubtless Hves also on P. cana- 

 densis. There appears to be little doubt but that the species 

 here figured is the form described by Say. since this is the only 

 common form in the Middle States, and the only one from 

 Missouri that will fit the original description.

Lopidea sayi new species. (PI. XIII, fig. 5). 



$. Length 6.1 mm., width 2.1 mm. Slightly smaller than staphylcac 

 but very similar in coloration, the antennae being more nearly linear ; 

 bright yellow to light orange, the scutellum and more or less on each 

 side of the com.missure, fuscous ; base of the head and each side of 

 the median line of the front, tylus. rostrum, antennae, membrane, 

 femora and tibiae, black. Sternum and sometimes part of the venter, 

 fuscous ; genital claspers distinctive of the species. 



5 . Very similar to the male but with more fuscous and less orange 

 in the yellow.

Lopidea caesar (Renter). Caps. Amer. Bor., p. 67, 1876. (PI. 

 XIII. fig. 4). 

 This species was described by Renter (1876) under the new 

 generic name, Lomatopleura, with the type locality given as 

 Pennsylvania. It was later found that Uhler's Lopidea (1872) 

 was very similar to Lomatopleura and the only points of dif- 

 ference between the type species that could be fixed upon in 

 classification was in the linear and incrassate form of the an- 

 tennae. The writer has shown in a previous paper that the 

 thickness of the antennae varies in the different species, and
