210 THE CANADIAN ENTOMOLOGIST. 



Family VII. — HylotomiN/E. 



All the species belonging in this group or subfamily have always 

 3-jointed antennre, the third joint in the female being simple, while in the 

 male it is most frequently forked. Sometimes it is simple in the male as 

 in the female, but in this case, however, it is as a rule more pointed at 

 apex and more densely pubescent. 



The 3-jointed aniennje readily distinguish the family, and must 

 always be depended upon, since otherwise it approaches, in its thoracic 

 and abdominal characters, very close to the Lophyridce^ Perreyiidce. 

 and the Selandriidce. 



Since formulating my table for distinguishing the families I have 

 discovered a new genus without an anal cell. 



The family may be divided into two subfamilies as follows : 



Table of Subfamilies. 

 Front wings without a transverse nervure in the costal 



cell Subfamily I., Schizocerinae. 



Front wings with a transverse nervure in costal 



cell Subfamily II,, Hylotominse. 



Subfamily I. — Schizocerin.-k. 

 This subfamily is readily distinguished by the absence of a costal 

 transverse nervure. It comprises by far the greater number of genera 

 and species, and is widely distributed throughout the globe, the species 

 found in the tropics being especially handsome. 



The numerous genera may be easily recognized by the aid of the 

 following table ; 



Table of Genera. 



Marginal cell appendiculate 6. 



Marginal cell not appendiculate. 



Front wings with three submarginal cells 5, 



Front wings with four submarginal cells (rarely with the first trans- 

 verse cubitus subobsolete) 2. 



2. Lanceolate cell petiolate, the small cell at base obliterated by the 



short anal vein uniting with the median 3. 



Lanceolate cell longly contracted, nearly petiolate, but always with 

 a small closed cell at base. 



Second submarginal cell receiving both recurrent nervures, or 

 the second recurrent is interstitial with the seconc' 'ransverse 

 cubitus 4.
