2U) THE CANADIAN ENTOMOLCKHST. 



eye ; a narrow oblique black line udder front wing, a line over base of 

 hind legs, and margin of pronotum black ; noium brown, but the median 

 prolongation is yellowish. Femora pale, each with middle and apical 

 bands of brown. Wings hyaline, apical marginal area brownish, some 

 cross-veins in costal and radial areas margined with black, one or two 

 under bulla are more broadly margined. The wings are rather long and 

 narrow ; about six costals before bulla and thirteen or fourteen beyond. 

 Length, 8 mm. 



From Middlesex Fells, Mass, August ; by the black spots under 

 antennje it is near to H. interpttnctata^ but separated by absence of the 

 dash in front wings. 



H. pulchella and //. terminaia Walsh. 



I think both of these are good species ; in life //. pulchella is very 

 pale, almost whitish-hyaline ; while H. tenninata has a dark thorax, a 

 darker tip to the abdomen, and the stigmal dots are distinct, as well as 

 other marks on the segments, at least in fully-coloured sj^ccimens. It is 

 very close to // luridiptnnis, but smaller. 



//. ititerputictata Say, and // Canadensis Walk. 



Both of these have the black dash under the bulla, but the former is 

 pale, yellow or greenish, while //. Canadensis is very dark and larger, and 

 more northern in distribution. 



//. flaveola Pict., is, 1 think, a synonym of //. interpunctata. 

 This species is very abundant over the Eastern States ; the female has a 

 prominent black dot above each lateral ocellus, but not the spots under 

 the antennce. 



H. maculipennis Walsh. 



This is readily known by the heavily-marked costal cross-veins ; it is a 

 small species, with rather narrow wings ; each abdominal segment has on 

 the sides an oblique dark stripe (not an apical band). 



//. simplex Walsh. 



A small form which may be this species occurs near Washington, but 

 is rather too small. The wing is narrow, like // maculipennis^ but wholly 

 unmarked, and the venation pale. 



H. flavescens Wahh. 



This is a wholly pale species, of fairly large size. I have it from 

 St. Anthony's Park, Minn.
