KO.1108. PROCEEDIXGS OF THE NATIOXAL MUSEUM. 295 



Spotted aud dotted with brown, the tibiae with a browu dot at base of 

 many of the spines, tarsal joints interrupted with brown. 



Length to tip of wing-covers, 4i mm.; width of pronotum, l:^mm. 



Type.—^o. 3130, U.S.X.M. 



Only two specimens of this modest little species are in the collection. 

 It somewhat resembles Jassus semlnudus. Say, in pattern of marking 

 and colors, but it is a much wider insect, more wedge-shaped posteri- 

 orly, aud with a more acute vertex. 



LIMOTETTIX?. species. 



Twelve specimens of a long and narrow species related to Belto- 

 cephalus are present in one of the boxes. This insect has so much resem- 

 blance to the European insects of this type that I hesitate to describe 

 it, believing that it must have been published heretofore by some of 

 the German or Scandinavian entomologists. 



The Psyllidai of the collection have been worked up by Mr. E. A. 

 Schwarz, aud his descriptions are herewith appended. 



ANOMONEURA, Seh\varz, new genus. 



Head strongly inclined : plates of vertex anteriorly obliquely trun- 

 cate aud subtriaugularly produced near the anterior ocellus: frontal 

 processes cone-shaped, depressed below the level of the vertex: eyes 

 large globular : anterior ocellus visible from above: antennie long and 

 slender: third joint much longer aud thinner than the second. Pro- 

 notum strongly ascending posteriorly, lateral impressions distinct; 

 dorsulum transverse, slightly ascending posteriorly. Fore wings elon- 

 gate, membraneous, of equal width from middle to apical fourth, apical 

 edge rounded but not regularly so, the tip of the wing being much 

 nearer to the anterior than to the posterior costa ; petiolus cubiti about 

 half the length of the discoidal part of subcosta : a long pterostigma : 

 radius slightly curved and normal at its basal half, beyond the middle 

 giving forth two (sometimes three, or even four) parallel cross veins 

 which run obliquely through the radial cell to the outer costa; at apical 

 fourth the radius bifurcates, thus forming a large marginal cell, which 

 is crossed by the fourth furcal vein : stem of second fork greatly arched 

 at basal half: discoidal cell closed, first marginal cell much smaller than 

 the second; fourth furcal vein running in the tip of the wing; hind 

 tibi* not toothed at base; genital plate and forceps of male without 

 appendages. 



Belongs to the tribe Psyllini and agrees with the genus PsyUa (as 

 defined by Pr. Loewi in shape of the body aud in formation of cephalic 

 parts, but ditfers in the form of the fore wings, and more especially in 

 the venation. The latter is altogether most unusual, and would have 

 been considered as an accidental abnormity if a single specimen only 

 had been examined. The number of accessorial veins connecting the
