New North American Heteroptera. 



By E. P. Van Duzee, Buffalo, N. Y. 



The species described below have come into my hands for 

 study from collectors in various parts of the country during 

 the past five years. It is often annoying and undesirable to 

 have species sent out under MS. names, especially if the pub- 

 lication of the descriptions is long delayed, and this is my ex" 

 cuse for the perpetration of a fragmentary paper such as this. 

 All of these are interesting additions to our fauna, and in each 

 case were received from well known and experienced students 

 of our insects. 



Narnia snowi n. sp. 



Broader and less narrowed posteriorly than femorata and its allies. 

 Pale ferruginous testaceous ; head, front of the prothorax, deflected base 

 of the pronotum, scutellum, elytra, pectus, meso- and metapleura and 

 the dilatation of the posterior tibiae black or dark fuscous. Head with 

 the apex and a longitudinal line each side both above and below the base 

 of the antennae ferruginous. Prothorax and pale hind margin of the 

 metapleura coarsely, the scutellum and hemelytra finely and closely 

 punctured ; extreme tip of the scutellum and costa of the elytra ferrugin- 

 ous, the middle of the corium with a transverse linear white band, not 

 attaining the costal margin. Hind femora becoming piceous toward the 

 apex, the spines and tubercules black ; dilatation of the hind tibiae rather 

 broad, inner margin about twice the width of the outer and marked with 

 a white sub-basal spot, the edge beyond the middle and along the undi- 

 lated apical one-third sparsely spinose. Venter more or less mottled and 

 infuscated, with a strong sulcus reaching the apex of -the 5th segment. 

 Rostrum passing the middle of the fourth ventral segment, blackish, with 

 the basal joint pale. Antennae substantially as in femorata. Length 

 16 mm. 



Described from one female specimen received from Prof. F. H. 

 Snow and captured by him at Douglas, Arizona, in August. 



I have before me three male and two female examples of a 

 Narnia that I take to be femorata. In these, however, the 

 basal joint of the antennae is scarcely darker than the others, 

 the humeral angles are not " acute " although more prominent 

 than in the allied forms, and the transverse white vitta on the 

 corium is indicated only by an obscure band of white hairs that 

 may be almost obsolete in some examples ; the form of the dila- 

 tation of the hind tibiae is, however, exactly as described by
