acute ; touching the margin a little way back, each side, is a small tri- 

 angular yellow spot ; posterior angles subrectangular ; the posterior 

 margin waved each side of the center, where it is also a little yellowish. 

 Pectoral surface dull black, with very sparse sericeous scales exteriorly ; 

 the spots of the dorsal margin equally visible beneath 5 sternal margins 

 piceous. Legs dull pale piceous-yellow. Hemelytra broad, widening 

 posteriorly, velvety black, pubescent, sprinkled with golden pubescence, 

 spotted and dotted with bluish lead-color; the costal margin yellow, and 

 with five small yellow spots ; membrane bluish lead-color, with the nerv- 

 ures black. Tenter piceous black, densely, minutely sericeous pubescent, 

 the edges of the segments and the tip of the last one a little reddish- 

 ipceous. The connexivum is unspotted, and the surface of the terguui 

 black, polished, with rufo-piceous edges to the segments. 



Length, 5 millimeters. Width of pronotum, 2J millimeters. Width 

 across the hemelytra, scantily 3 millimeters. 



Inhabits Texas, Illinois, Eastern Massachusetts, Pennsylvania, and 

 Cuba. A specimen from near Dedham, Mass., collected near water, in 

 April, -was sent to me by F. G. Sanborn ; also, an immature one from 

 near a spring, in York County, Pennsylvania, was kindly given to me 

 by Dr. F. E. Melsheimer. 



The species has thus far been detected in but a very few places, and 

 only by the most scrutinizing collectors. It occurs near water in places 

 which are overgrown with marsh-plants. It may be at once known from 

 the European one by being wider posteriorly than in front, and by the 

 absence of the quadrate yellow spots from the connexivum. 



A specimen from Cuba, obtained by Professor Poey, has the spots of 

 the costal margin of the hemelytra almost obsolete ; but it agrees with 

 the United States form in all other respects. 



The pattern of marking on the costal margin of the hemelytra is-in 

 close imitation of that commonly seen upon the connexivum of various 

 Pentatomids, Scutellerids, and Coreids. It can serve no purpose in pro- 

 tecting the creature from its enemies, and does not belong to one sex 

 more than to the other. Characters of this kind are usually acquired at 

 the time of changing the last nymph-skin to become an imago.

Inhabits Texas, Arizona, Indian Territory, Missouri, Illinois, Michi-

 sections of Maryland, there are two broods annually, the one in May and 

 the other in August. 



Prof. Cyrus Thomas observed this species leaping to seize (as he sup- 

 posed) Xya tenninalis, in the State of Illinois.
