276. Kolla geometrica Signoret. 



Taken with the last but much less abundant. It has a 

 longer vertex and unicolorous green elytra on which are three 

 pale oval spots before the blackish membrane. 



277. Kolla Hartii Ball. 



Ft. Myers and Estero. Still smaller than geometrica and 

 with, a shorter head. I took two males and two females; the 

 latter were colored exactly like the males instead of being 

 lighter with pale nervures on the elytra. In both sexes the 

 whole insect is deep shining black becoming fuscous toward the 

 apex of the elytra, before which is a subhyaline spot on the 

 costa. The legs and markings of the head are white as de- 

 scribed by Dr. Ball. 



Kolla similis Walker. 



I did not take this species in Florida although Mrs. Slosson 

 has done so. I notice it here to call attention to the fact that 

 Dr. Distant in his Rhynchotal Notes No. 44, reverses this 

 species and herbida Walker, claiming that while Walker mixed 

 these two species in his descriptions his types show that our 

 identifications are wrong. These descriptions by Walker are 

 accurate and entirely adequate for the determination of these 

 very distinct species and it is simply a case where the types and 

 descriptions have become reversed, and I cannot see as we have 

 any choice but to follow the descriptions : Otherwise what would 

 be the use of publishing a description at all if the type label 

 alone carries authority? The type must agree reasonably well 

 with the description and I confess I can see no alternative in 

 this case but to follow the nomenclature pointed out by me in 

 1894 (Ent. News, v. p. 155,) identifying similis Walker with 

 the southern form and herbida Walker with our northern 

 Helochara communis. 



278. Diedrocephala coccinea Forster. 



Crescent City, Sanford and Ft. Myers. These are of the 

 bright scarlet variety described by Say as j.-vittata. This is 

 the southern form of this species and is represented in my col- 

 lection by material from North Carolina, New Jersey, Ohio, 

 Kansas and western New York. The larger green northern
