contrast. There are two series of species found in this genus. 

 In the first or typical group the insect is pale yellow to piceous, 

 polished; apex of the head smooth with the carinae there obscure. 

 This group of species much resembles Megamelus but has the 

 median carina of the front forked distinctly below the apex of 

 the head although the two branches are close together and obscure. 

 The second division of the genus includes opaque brown species 

 with pale carinae and elytral nervures and the frontal carinae 

 distinct over the apex of the head. This genus and the more 

 southern Perigriniis are amply distinct from Dicranotropis and 

 there is no occasion for confusing them as has been done by Mr. 

 Crawford. 



Key to Brachypterous Forms. 



1. Polished, fulvo-testaceous to piceous-black ; el)rtral nervures con- 



colorous and indistinct 2 



Opaque brown species with the elytral nervures usually pale 6 



2. Color piceous or almost black 3 



Color fulvous or fulvo-piceous, at least on the elytra 5 



3. Apical margin of the elytra pale 4 



Apical margin of the elytra concolorous, piceous ater 



4. Anterior and intermediate tibiae black or nearly so marginatus 



Anterior and intermediate tibiae pale, lineate with brown ..pallipes 



5. Head concolorous or paler than the pronotum and elytra ..delicatus 

 Head and pronotum black or nearly so guttatus 



6. Face with a broad white band crossing the apex of the front, base 



of front maculated aphidioides 



Face without a white band above the usual transverse black band 7 



7. Lower surface and a broad longitudinal vitta on the tergum pale 



yellowish ; elytral nervures concolorous dorsalis 



Coxae and apex of the front only pale; median vitta of the 

 tergum but obscurely pale brunneus

The black anterior and intermediate tibiae seem to be character- 

 istic of this species and will serve to distinguish it from the 

 closely related pallipes. It seems to be distributed throughout the 

 United States and Canada and should be found in Connecticut. 

 Pissonotus basalis Van Duzee will probably be found to be but the 

 macropterous form of this species. 

 P. pallipes Van Duzee. 



Bull. Buff. Soc. Nat. Sci., v, 238, 1897. 



Smaller than the preceding with the feet entirely pale, lineate 

 with brown. It also is a widely distributed form and must occur 

 in Connecticut. 

 P. ater Van Duzee. 



Bull. Buff. Soc. Nat. Sci., v, 237, 1897. 



The concolorous hind margin of the elytra is the best superficial 

 character by which to distinguish this species. It has been 

 reported from New York to Florida.
