GENUS SELANDRIA. 193 



Genus SELANDRIA. 



Sclandria, Leach, Zool., M., iii, 126. 



Wings with two radial and four cubital cellules. Lanceolate cellule 

 open. Posterior wings with the transverse cubital and recurrent ner- 

 vures present, and placed not far from each other. Post-costal nervure 

 thickened and almost joined to costal in front of stigma. Antenna) 

 shorter than abdomen, thickish, the third joint much longer than fourth. 

 Eyes generally reaching to base of mandibles. Clypeus slightly incised. 

 Patellao distinct. Body short, ovate, shining. ForTrophi, see PI. XIII, 

 fig. 9. 



The basal nerve is curved ; the 1st tr. cubital nervure 

 is sometimes absent. The colour is either black 

 throughout, with yellow, or black and white legs, or 

 the abdomen is luteous, with the legs and part of 

 thorax of the same colour. They are sluggish, heavy 

 flying insects. 



The larvae are of the usual shape, but thicker com- 

 pared to the length than those of Taxonus or Strongy- 

 logastcr. So far as is known at present they feed 

 either on grasses or ferns. 



Selandria comes nearest to Sir ongylog aster in neura- 

 tion, but differs in the shorter, more thick-set body, 

 shorter and thicker antennae, and in the thickened sub- 

 costal nervure. The wings, too, are broader, and the 

 hinder tarsi shorter compared to the tibiae. Eriocampa 

 is easily separated from it by the lanceolate cellule 

 having an oblique cross nervure. 



The species are confined to the European subregion, 

 the Neartic region and Central America ; there are 

 ten species known from America, and twelve from 

 Europe. 



Synopsis of Species. 



1 (6) Abdomen luteous. 



2 (5) Eyes nearly touching the base of the mandibles ; labrum and 



base of antennae black. 



3 (4) Third antennal joint not much more than double the length 



of fourth. Second transverse cubital nervure not inter* 

 stitial. Serva.
