California.) 



As the author of this species has given a really excellent descrip- 

 tion, it is rather irritating to find it synonymized by Karnj^^* 

 under C. saUator, where, without material for comparison, that 

 author briefly states that it is a smaller variation. 



The species is known only from the salt marshes about San Diego 

 Bay, California; the type series of three males, two females and 

 one immature female in the Morse Collection and Museum of 

 Comparative Zoology, and in addition three males and one fe- 

 male in Philadelphia, have been examined. 



Conocephalus gracillimus (Morse) (PI. XV, fig. 8; XVI, XVII and XX, 5; 

 XVIII, 9 and 10; XIX, 11.)

The present species belongs to a small group, the other species 

 of which are Antillean and tropical American, which is in the 

 main distinguished from the forms more nearly related to C. 

 fasciatus by the majority of the characters given in the key for 

 the present insect. When compared with fasciatus, the more 

 produced vertex and broader convex callosities of the lateral lobes 

 of gracillimus are found to be characters which are somewhat less 

 conspicuous than might be expected; the present species is more
