NORTH AMERICAN NEUROPTERA. 263 



15. Goiii|>hii$« spec. 



One young nympha from Newport, Ky., by Miss Willard, 1881- 

 Length 23 mm. Body flat, hairy ; diff"ers as follows from the nympha 

 supposed to belong to G. fratenms. 



Third joint of antennEe a little longer, more cylindrical; fourth rudimentary, 

 black: mask nearly one-half longer than broad, somewhat sloping to base; mid- 

 dle third straight; palpus as by G. fraternus, bat only three strong teeth near 

 tip ; wing cases reaching 3d segment ; abdomen flat, three times longer than broad, 

 a little increasing to 7th segment, the rest tapering slowly; segment 9 one-third 

 longer than 8 : segment 10 very short, one-sixth of 9th ; lateral spines on 6 to 9 

 sharp, the last one twice the length of segment 10 ; dorsal hooks none, but the 

 apical margin of 9th segment with a broad, triangular, flat projection, in the mid- 

 dle as long as segment 10 ; appendages twice the length of last segment, triangu- 

 lar, broad, sharp, the laterals nearly as long as the other; legs slender, shorter, 

 posteriors reaching segment 7, third joint of posterior tarsi as long as the two 

 basals. 



There is no clew for the species to which the nympha belongs. Per- 

 haps it may be G. minutus. 



16. Ooniphtis exilis (raised). 



Two nympha skins, one of them raised by Mr. F. Sanborn in Wor- 

 cester, Mass., May 25, 1878, and two younger nymphae from Brookliue 

 and Salem. Mass. Length 24 to 19 mm. 



Body rather slender, moderately hairy; head cordate, notched behind; angles 

 blunt; third joint of antennse about twice as long as both, basal little dilated, bent 

 up, flat above, truncate on tip, fourth joint very short, ovoid ; mask quadrangular, 

 a little longer than broad, narrowed at base, front border very faintly rounded on 

 middle third, which is not produced, with a comb of flat scales; palpus scarcely 

 meeting, ending in a strongly bent and pointed hook with four strong teeth inside ; 

 movable hook long, slender, arcuate ; wing cases reaching partly 4th segment ; ab- 

 domen a little more than three times longer than broad, flat, tapering slowly after 

 6th segment; segments of equal length, 9th a little longer than 8th; 10th half of 

 9th, cylindrical, ventral margin a little produced in the middle; lateral spines on 

 6 to 9, the last one-third of 10th ; dorsal hooks very small, pointed on 6 to 9 ; scars 

 as usual; genitals marked by both sexes; appendages as long as last segment, 

 pyramidal, broad, sharp, laterals a little shorter; legs slender, long, posteriors 

 reaching nearly 9th segment, third joint of its tarsi scarcely longer than second. 



Eleven nymphse in alcohol from Kentucky by Mr. F. G. Sanborn ; 

 all stages from full grown 2G mm. to very young 12 mm. are very much 

 alike to those of G. exilis. The head of the younger nymphae is only 

 half as broad as the abdomen, which is very flat ; the dorsal hooks in 

 some are indicated on segments 2 to 9. As G. exilis is found in Maryland 

 it may exist also in Kentucky ; the tarsi are yellow. 



A full grown nympha 27 mm. long from the Potomac, Virginia, 

 August, by Prof. Shaler I am not able to separate from those from Ken-
