Order Neuroptera. Fam. Psocidae. 



Type of the Genus, Coniopteryx Tineiformis Curt. 



CONIOPTERYX Curt. 



Antenna: inserted between the eyes, as long or longer than the 

 body, filiform, composed of numerous pubescent and submoni- 

 liform joints, from about 20 to 40 in number, basal joint the 

 stoutest, 2nd oblong, the following globose, gradually becoming 

 ovate towards the apex, the terminal joint being elongate-conic 

 ( 1 , portions of the base and apex) . 



Labrum semicircular, slightly concave before, with 2 bristles 

 on each side (2). 



Mandibles subtrigonate, apex acute with a notch on the inside 

 forming a rounded shoulder (3) . 



Maxilla small, terminated by 2 curved lobes, the inner one 

 linear and rigid, the other a little broader, more membranous 

 and rounded at the apex. Palpi rather long and porrected, 

 forming a kind of beak, and 5-jointed, first 4 joints nearly of 

 equal length and stoutness, 1st oblong, 2nd 3rd and 4th obovate, 

 the two latter truncated obliquely, 5th long andsublanceolate (4). 

 Mentum subquadrate. Palpi triarticulate, first two joints sub- 

 ovate, 3rd large ovate and compressed (5). 

 Head orbicular, depressed in front ; neck distinct : eyes near the an- 

 terior angles of the head, remote and ovate : ocelli undiscovered. 

 Thorax gibbose and tuberculated. Abdomen short, elongate-ovate. 

 Wings deflexed when at rest, rounded and poiodered, the superior 

 very ample and larger than the inferior, which are sometimes very 

 small; many longitudinal nervures and a few transverse ones, forming 

 3 discoidal cells in each (9). Legs, anterior the shortest, posterior 

 the longest : tibiae compressed, longer than the thighs, except in the 

 1st pair : tarsi short slender and 5-jointed, basal joint the longest,

'PsociFORMis Haliday's Mss. — Curt. Guide, Gen. 741*. No. 2. 



Length -f- of a line, expansion 4 lines. Dead pearly white,_ an- 

 tennae twice as long as the body, composed of nearly 40 joints, 

 subochreous : superior wings very ample and distinctly irides- 

 cent ; inferior wings small. 



In the Cabinets of Mr. Haliday and the Author. 



This group may be distinguished from Psocus by the greater 

 number of joints in the antennae palpi and tarsi, by the pow- 

 dered wings (from whence the name of Coniopteryx) and the 

 absence of a stigma.
