GENUS SOIOPTERYX. 155 



men taken by the late Ed \vanl Newman at Darenth 

 Wood, and one in Mr. C. W. Dale's possession from 

 Dover. 



It is purely a southern insect. The Eev. T. A. 

 Marshall, F.L.S., informs me that it is common in the 

 Pyrenees, where it flies in the sunshine. It also 

 inhabits France, Switzerland, Tyrol, Hungary, Italy, 

 Dalmatia, Greece and Russia. 



Genus SCIOPTEEYX. 



Sciapteryx, Ste., 111., vii, 56 (1835). 

 Eniscia, Thorns., Opus., Ent., 299. 

 Allantus, Auct. 



Wings : lanceolate cellule broad, with a short perpendicular nervure. 



Antennae pilose, short, thick, scarcely longer than the thorax; the 

 first joint very large, with a short pedicle at the base, truncated at the 

 apex ; double the length and thickness of the second, third more than 

 double the length of the fourth ; the fifth to eighth somewhat swollen, 

 varying in length ; ninth conical, thinner than the others. 



Clypeus with a semicircular emargination at the apex, the outer edges 

 sharp. 



Labrum emarginated at the apex. 



Head broad, thick ; front thick ; antenna) placed wide apart ; vertex 

 thick, its sutures scarcely visible ; frontal sutures entirely so. Eyes 

 small, scarcely converging, considerably removed from the base of 

 mandibles. 



Abdomen depressed, short, thick. Blotch large. 



Legs longish ; tibiai longer than the femora. 



The position of the eyes separates this genus 

 readily from Allantus. It differs also in the body 

 shape and in coloration, being much shorter and 

 thicker, with the abdomen more depressed than in the 

 last-mentioned genus. Characteristic, too, is the 

 emarginated labrum, while the antennaB are not so 

 thickened at the apex, being also pilose. So far as is 

 known the species are black, with the apical segments 

 of abdomen lined with white. 



I am not aware that Sciopteryx is found elsewhere 

 than in Europe and North America.
