302 THE CANADIAN ENTOMOLOGIST. 



broad and angled basally, but not cleft ; no pulvillus {Chelostoma 



ftorisomne has a large pulvillus) ; first abdominal segment with a distinctly 



margined though shallow concavity. 



Einphoropsis c'nieraria (Smith). 

 Afiihopora cineraria, Sm., ? . — Easily known by its rather large 

 size and grayish appearance, rather like a large Clisodoji terminalis ; hair 

 on outer side of hind tibiae entirely shining orange-golden ; hair on sides 

 of face is black, and black hair is mixed with that of mesothorax ; the 

 venation is of the type oi E. fioridana, marginal cell comparatively long, 

 and recurrent nervures entering it at ends of second and third submarginal 

 cells, though not meeting transverse cubital nervures ; third submarginal 

 cell strongly contracted above. The male has a white clypeus, very 

 broadly margined laterally with black ; the white area is broader than 

 long, and is a curious sort of pinkish-white. 



The Mexican species of Emphoropsis (placed by Smith in Habro- 

 poda) represent a distinct section of the genus, known by the light area 

 on the clypeus being much longer than broad, and separated from the 

 lateral face-marks. Our E. floridana differs also from the Mexican ones 

 by its much broader face, with a broader and shorter clypeus. The 

 Mexican E. agilis has maxillary palpi slender, 6-jointed, second joint 

 longest, last two small ; paraglossaj short ; galea long and parallel-sided, 

 as long as labial palpi. Male with third antennal joint not elongated, 

 though its apical half is broadened. The second joint of maxillary palpi 

 is much longer than first, but not as long as the last three together. The 

 Mexican species are readily separated, thus : 



Pubescence of thorax black Emphoropsis terminata (Smith). 



Pubescence of thorax not black i. 



1. Ground-colour of abdomen red E. agilis (Sm.). 



Ground-colour of abdomen black or largely so 2. 



2. Pubescence of thorax bright orange-fulvous, anteriorly with black hairs 



intermixed E.fulva (Sm.). 



Pubescence of thorax without black hairs intermixed 3. 



3. Pubescence of thorax light yellowish ; clypeus without black marks on 



the yellow ; apical part of abdomen not red . .E. monteziania (Sm.). 

 Pubescence of tb.orax bright orange- fulvous ; clypeus with two black 

 streaks on the yellow ; apical part of abdomen with red 

 ground-colour E. bombyformis (Sm.).
