568 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 46. 



This genus is erected, provisionally, for a species of which only one 

 immature male is known. Although this may not ordinarily be good 

 poUcy, yet in this instance it is justifiable for the reason that the 

 specimen at hand is a nymph of a very late instar, and also because 

 the principal generic characters used here happen to be about the 

 same for adult and late nymph. This is made a doubtful genus 

 because it is based upon an immature specimen. 



LEPTICUS OCULATUS, new species. 

 Plate 45, fig. A. 



Length of body, 3.5 mm.; width of vertex, 0.22; width of frons, 

 0.5; antennae, I, 0.13; II, 0.28. General color light brown, eyes 

 darker; frons dark reddish brown with a white band across clypeal 

 margin and an arcuate band across midway; antennae light brown 

 with dark longitudinal stripes; legs lighter. 



Head long, fuUy as broad as prothorax, strongly carinate; vertex 

 about two and a half times as long as broad, apical half converging 

 narrowly, nearly one-third its length beyond eyes; frons abruptly 

 broadened, easily visible from above on each side of vertex, with 

 two median carinse weU separated, close together above, parallel with 

 sides'; about two and a third times as long as broad, equally broad 

 above and below, ovate; gense small; clypeus large; eyes very large, 

 long, bulging with no emargination nor absence of facets beneath; 

 antennae moderately long, terete, I short, about one-fourth as long 

 as II. 



Thorax quite long; pronotum extending weU forward between eyes. 

 Legs moderately long; hind tibiae with three very short lateral spines; 

 calcar a Uttle more than half as long as basal tarsus. Abdomen long, 

 genitalia immature. 



Described from one male in a late nymphal instar, from Managua, 

 Nicaragua (Baker). Being immature, it has numerous pits on the 

 frons, notum, and abdomen, as in many immature Fulgorids, but 

 whether or not the mature forms retain these is not known. 



Type-specimen. — In collection of Pomona CoUege. 



After the last nymphal moult the thorax takes on a totally dif- 

 ferent aspect, so that the description of that had to be omitted from 

 the above. The head, however, remains approximately the same, 

 hence these characters are valid. In most nymphs of Delphacidae 

 the tarsi are all thi-ee-segmented as in the adults; in this species the 

 first two pairs are two-segmented. 



Genus EUCANYRA, new genus. 



Vertex narrow, protruding beyond eyes; frons not broad, tricari- 

 nate, rather long; rostrum long; eyes large, entire, not emarginate 

 beneath, but some facets wantmg above antennal insertion; anten- 

 nae long, prominent, terete, second segment longer than first, often 

 tuberculate. Prothorax short, tricarinate; scuteUum large, broad,
