DESCRIPTION OF A PECULIAR NEW LIPARID GENUS 



FROM MAINE. 



BY B. NEUMOEGEN, NEW YORK. 



Dyaria, 710V. gen. 



Head prominent, with a high vertical tuft. Front nearly square, 

 rather higher than broad ; slightly convex. Vertex small, with a low, 

 conical central projection. Ocelli absent. Eyes large, naked, reaching 

 as far as the front and above the vertex. Antennas inserted far apart, 

 close to the margin of the eyes. In $ lengthily bipectinate, the pec- 

 tinations diminishing gradually, the distal third being bare. To judge 

 from the fragments of a $ specimen with broken off antennas (only 6 



joints left to judge from), the $ antennas are 

 apparently simple. Palpi exceeding front by 

 two thirds their length ; second joint very 

 large, third small. Tongue weak, but 

 moderately long, coiled. Thorax robust, 

 about as broad as long. 



Primaries well drawn out, about twice as 

 long as broad. Costa straight, apices 

 pointed and exterior margins well rounded. 

 Vein 1 free and straight, furcate at base. Median four branched. Vein 

 2 arising very much beyond middle of cell ; 4 and 5 approximate at 

 their origin, at lower angle of cell. Cell closed, rather narrow and near 

 to the costal edge. Cross vein bent inwardly at centre. A long, very 

 narrow accessory cell, reaching from the apex of discal cell more than 

 half way to apex of wing, its sides in apposition except at the two ex- 

 tremities, so that it is closed for the greater part of its length. Vein 6 

 from the under side of accessory cell, near its origin ; 7 and 10 from the 

 end of accessory cell, on each side of a stalk, which becomes furcate very 

 close to the apex of wing, thus forming veins 8 and 9. Vein 1 1 from the 

 subcostal beyond the middle of the discal cell. Vein 12 free from base.
