486 HEMIPTEROIvOGICAL GLEANINGS 



to be trusted. In typical invitus they are fuscous with the 

 extreme base and apex of the first joint pale; in the pale 

 variety of invitus joints three and four and the broad apex of 

 two only are fuscous; in belfragei the apex of the second joint 

 is black and the base at least and sometimes nearly the whole of 

 this third joint is pale; in fasciatus and tenellus the antennae 

 are pale with the apical two joints more or less infuscated; more 

 in fasciatus than in tenellus. In the markings of the pronotum 

 and elytra these four species seem to run together; invitus 

 when mature nearly always has a broad blackish ray on either 

 side of the pronotum which is sometimes seen in belfragei but 

 never in fasciatus or tenellus so far as my observations go; 

 belfragei and fasciatus are usually more or less greenish while 

 invitus aud tenellus are, I think, never so when mature. In bel- 

 fragei and fasciatus and in the paler forms of invitus there is a 

 fuscous fascia across the broadest part of the corium which may 

 extend over the clavus to a greater or less extent. In tenellus 

 the elytra are practically unicolorous. 



Tropidosteptes canadensis n. sp. 



Nearest to amcenus var. palmer i but darker with the 

 antenna? stouter and black at base. Length 5 mm. 



Structurally this species is very near amoenus. It differs principally in 

 having the antennas obviously stouter with the first joint shorter; the prono- 

 tum, scutellum and elytra more closely punctured and the rostrum shorter 

 reaching only to the extremity of the intermediate coxa?, whereas in palmeri 

 they attain the hind edge of the metasternum. 



Color an obscure yellowish testaceous, polished. Clypeus shining black, 

 the tumid cheeks and lorse of a lighter yellowish. Eyes nearly black; 

 basal joint of the antenna? black, the apical dusky. Disk of the pronotum 

 on either side, clavus, narrow costal and broad apical margin of the corium 

 and a dis^a! spot on the base of the scutellum obscure brownish, the latter 

 bisected by a narrow median pale line. Callousities infuscated. Membrane 

 slightly infuscated, its disk, a spot at the apex of the cuneus and another 

 a little beyond it, paler; nervures nearly concolorous, the basal angle with 

 a fuscous mark. Hind femora with two narrow fuscous subapical rings 

 which are nearly obsolete in one specimen. Tip of the rostrum and tarsal 

 claws black. 



Described from two female examples taken on white ash 

 by Mr. W. Metcalfe at Ottawa, Ont., August 1st 1904. It is 

 not unlikely that this species may vary in color somewhat as 

 does amcenus but the structural characters mentioned above 

 make it certain that it is not a variety of that species. The
