P. exaptus (Say). (PL xviii, 24.) 



Jour. Acad. Nat. Sci. Phila., iv, 313, 1825. 



Color very variable, entirely black to pale yellowish or red with 

 black markings, in the latter case the black often distributed as 

 follows : head except front margin, transverse bands on disk and 

 hind margins of pronotum, median area of scutellum, hemielytra 

 except costal margin. Length 5-7 mm. 



Several color varieties have been named but it is hardly worth 

 while to enumerate them, as intermediate forms are more common 

 than those that fit the descriptions.

Rhacognathus Fieber. 



Dark, very strongly punctate species somewhat resembling 

 Brochymcna in general appearance; scutellum broadly rounded at 

 tip, sides parallel in apical half ; anterior tibiae unarmed, sulcate 

 above; abdomen without basal spine; second rostral segment not 

 shorter than the third and fourth together, third not longer than 

 the fourth ; bucculae strongly elevated ; f rena extending about to 

 middle of scutellum; metasternal orifices small, canal obsolete; 

 male without abdominal sericeous patches. This genus includes a 

 single North American species. 

 R. americanus Stal. 



Enum. Hemip., i, 77, 104, 1851. 



Pale yellowish brown in ground color, more or less suffused 

 with black, surface with strong, black, more or less confluent punc- 

 tation, producing a general dark effect; lateral pronotal margins, 

 median line of pronotum and scutellum, base of third antennal 

 segment, connexival bands, and markings of legs, pale ; membrane 

 black. 



Juga longer than tylus, contiguous in front. Lateral margins 

 of pronotum straight, crenulate anteriorly ; lateral angles promi- 

 nent. Connexivum widely exposed. Form broadly oval. Length 

 9-1 1 mm. 



This is a rare species, taken once in Massachusetts. 



Mineus Stal. 



This genus contains a single North American species, having the 

 juga and tylus approximately equal ; lateral pronotal margins 

 nearly straight, obtuse, entire ; scutellum rather narrowly rounded 

 apically, the f rena extending a little beyond the middle ; tibiae
