SAT’S HETEROPTEROUS REMIPTERA. 
Belostoma, Latr. 
1. B. Jluminea, Fuscous; bead before tbe eyes attenuated; 
feet spotted. 
Inliab. U. S. 
Body rather long ovate, grayish or fuscous: head rapidly 
tapering from the anterior cauthus of the eyes to the tip, form¬ 
ing in that part an equilateral triangle, of which the tip is 
obtuse, but less than one-fourth the breadth of the space 
between the eyes; the anterior lobe or nasus hardly reaches the 
line between the anterior canthus of the eyes: thorax a little 
emarginate before, and less obviously so on each side, posterior 
to the transverse suture and a narrow lateral margin, paler; 
tibiae and tarsi each with three black spots or interrupted annu- 
lations. 
Length from seven-tenths to four-fifths of an inch. 
This species is no doubt related to B. rustica, Fabr. but he 
describes tho thorax of that species as being white before. 
Like that species the female carries her eggs upon her back. 
Stoll’s figure of the rustica represents it of a short ovate form. 
It has an extensive range. I purchased a specimen taken at 
New Ilaven, one was sent to me from Georgia by Mr. Oemler of 
Savannah and it i3 found in Pennsylvania and in Indiana and 
Louisiana. 
Yar. A. immaculata, Much smaller; lateral margin of tho 
thorax depressed and slightly reflected; feet immaculate. 
Length half an inch. 
Most probably a distinct species, but I have seen but one 
specimen. 
As tho large North American species does not appear to have 
boen noticed I will add a description of it. 
2. B. grisea, Oblong-oval; head before the eyes very short, 
not attenuated; beneath with three blackish vittae. 
Inhab. U. S. 
Body oblong-suboval, slightly wider behind the middle, gray- 
isflrbrown varied with fuscous or blackish, particularly on each 
side of tho disks of the thorax and scutel : head between the 
eyes hardly tapering from the base to the tip; from the anterior 
'■anthus of the eyes to the tip, shorter than broad, not narrowed :
