deep piceous-black clypeus is replaced by rufo-flavus, or honey-yellow. 

 In the Harrisian specimen the clypeus is rather flavo-piceous, and the 

 basal margin of pronotum tinged with rufo-piceous. The lateral re- 

 curved margin of prothorax is only slightly rufous, and the abdomen, 

 both above and below, rufo-piceous, clothed with remote yellowish 

 hairs. 



The darkest specimens have the pronotum all over deep black, 

 highly polished, as also the upper side of the head; with the clypeus 

 rufo-piceous, and only the base of gula yellow; the hemelytra fusco- 

 piceus, and the membrane a little paler; the abdomen entirely deep 

 black, polished. A specimen from Lake Winnipeg has legs almost 

 entirely nigro-piceous.

Two individuals now remain in the collection, labelled " Ala- 

 bama." They are small specimens of the normal type, common to 

 the Middle States; the legs and antennae being deeper black than 

 such as I have seen from Louisiana and Texas. It occurs also in 

 Massachusetts. A specimen is in my collection, which was collected 

 for me near Para, Brazil.

A single pupa is in the collection, collected in North Carolina. It 

 is sometimes very common in Maryland, and hibernates beneath 

 stones. Dr. Harris probably never saw the adult insect, or he would 

 not have included it in the same number as the preceding species. 

 Although closely related in structure the two species seem to keep 

 always apart, and notwithstanding that 1 have seen many pairs 

 in coitu, I have never yet observed the two kinds to unite sexually.
