THE CANADIAN ENTOMOLOGIST. 57 



apical cells hyaline white in sharp contrast. Face pale yellow, a black 

 band across between the eyes, narrowed on the front and emitting a line 

 under the vertex margin, clypeus and lower third of lone, black. 



Genitalia : female segment long and narrow, over twice the length of 

 the penultimate, narrowing posteriorly and terminating in two rounding 

 lobes separated by a broad notch ; male valve obtusely triangular, as 

 long as the ultimate segment, plates broader than the valve, long 

 triangular, over four times as long as the valve, their margins clothed 

 with long silky hairs. 



Described from eleven specimens from the National Museum ; from 

 Los Angeles Co., Calif. Coquillett collector. 



In shape and colour marking of vertex and pronotum this species and 

 Coquillett i are almost identical, but the venation of the elytra as well as 

 its colour pattern is quite different, and the genitalia are distinctive. 

 Those who consider the presence or absence of the second cross nervure 

 a good generic character would place these two species in different genera. 



Genus HULERIA, n. gen. 



Form long and narrow, almost parallel margined, vertex longer and 

 more angulate than in Parabolocratus, as long as its basal width, one- 

 third longer than the pronotum in the female, two and one-half times as 

 long on middle as against eye, disc flat, the margins inclined to be 

 elevated ; ocelli on the margin about one-fourth the distance from eye to 

 apex. Face in profile perfectly flat, retreating as strongly as in Becalus, 

 transversely convex ; the front broad above, the margins straight from the 

 ocelli to the rather small, parallel margined, clypeus. The upper part of the 

 front has a quite definite median ridge, which becomes narrower and more 

 elevated as it approaches the apex of vertex, leaving a narrow compressed 

 margin to the vertex. Pronotum twice wider than long, the anterior and 

 posterior margins nearly parallel, lateral margins straight; elytra very long 

 and narrow, evenly rounding at the apex, with a very narrow appendix ; 

 venation as in Thamnotettix, the anteapical cells very long, extending 

 more than half their length beyond the apex of clavus, apical cells very 

 short and regular. 



Type of the genus H. ^-punctata. 



The elevated ridge on front and general shape of face and vertex are 

 very similar to Cochlorhinus, but the venation and general shape of the 

 elytra are quite different.
