 Family IX.— Selandriid.^. 



After the removal of the Strongylogasterijia, which, to a certain 

 extent, form a connecting link between this family and the Tenthredinidse, 

 but which, on account of their elongate shape and their cephalic and 

 abdon)inal characteristics, I have ])laced with the latter family rather than 

 retain here, there need be no difficulty in separating the Selandriidce 

 from all the other families by the characters made use of in my table. 



The species have a peculiar habitus quite their own, and with a 

 little care one may easily recognize a Selandriid without even the trouble 

 of an examination. 



The head is more transverse, the temples much narrower, not nearly 

 so quadrate as in the Strongylogasterin?e ; the antennfe are shorter, the 

 scape or first joint not or rarely much longer than the pedicel or second 

 joint ; the wings are proportionately shorter and broader, the costal vein 

 being much dilated or broadened towards the apex, before the stigma ; 

 while the abdomen is much shorter, broader and oviform. 



I have separated the family into four subfamilies, distinguished as 

 follows : 



Table of Subfamilies. 



Lanceolate cell petiolate (in only a single genus Kaliosysphinga ^ Pseudo- 

 dineura, Konow, does it appear contracted, but in this genus the anal 

 vein is faint or sub-obsolete before uniting with the submedian vein, while 

 the anal cell in the hind wing is wanting). ..Subfamily L, Blennocampins. 

 Lanceolate cell contracted before the middle, but still open, and some- 

 times with an oblique or transverse nervure between it and the apex. 

 Antennas 4-jointed, the third joint very long, the fourth or last very 

 niiniite ...,.,.,, , Subfamily 11. , Blastigotominfe.
