360 HETEROPTEROUS HEMIPTERA. 



seutel blackish : hemelytra conspicuously liairy, with a [few] dull 

 yellowish spots, as well on the membrane as the cerium : pectus 

 a little varied with black; remaining inferior surface including 

 the feet immaculate. 



Length to tip of hemelytra under one-fourth of an inch. 



This species may be recognised by its more obviously hairy 

 vesture ; its color is also paler than usual in this genus. 



3. A. LUGUBRis. — Black ; membrane of the hemelytra, ob- 

 tusely [obsoletely] spotted. 



Inhabits Missouri. 



Body black, subopake : head between the antennae with three 

 3'^ellowish points : antennae first and second joints dull yellowish 

 before : thorax and seutel immaculate : hemelytra immaculate on 

 the corium, or with an obsolete dull yellowish point on the 

 middle of the tip ; membrane with two or three obsolete dull 

 yellowish spots, [on the ?] inner margin and tip : beneath with a 

 yellowish spot before each of the anterior feet ; feet pale yellow, 

 ish ; tibiae and tarsi more dusky : thighs, particularly the 

 anterior and posterior pairs, with a more or less dilated black 

 [805] line toward their tips : coxae black : anterior pair yellow- 

 ish at tip, remaining pairs slightly tipped with yellowish. 



Length to tip of hemelytra less than three-tenths of an inch. 



For this species I am indebted to Nuttall, who obtained it in 

 Missouri.

Body black, with short, scattered hairs : head with a trans-

 an impressed puncture before the impressed transverse line : 

 hemelytra with the exterior margin [and] three rather large spots 

 along the sub-margin, yellowish, membrane dull yellowish, with 

 black nervures and fuscous oblong spots in a transverse series 

 alternating with the nervures : feet and rostrum yellowish. 



Length to tip of hemelytra one-tenth of an inch. 



The interstitialis nob., which this resembles, has the exterior 

 margin of the hemelytra black and is much larger ; it has also a
