NORTH AMERICAN NEUROPTERA. 277 



raent 9, middle space a little larger; anal appendages very short, pyramidal, 

 sharp, all of equal length ; legs short, very hairy ; the four anteriors about equally 

 distant, hind legs more separated; femora arcuated, tibia straight, longer, second 

 joint of tarsi knife shaped, claws very short, blunt; hind legs more slender, lon- 

 ger, reaching 6th segment, third joint of tarsi as long as the two basal, claws 

 longer, pointed. 



The only specimen is beginning transformation ; head and thorax are 

 split as usual, but not yet taken out, only the base of the wings is begin- 

 ning to show outside the wing cases. In lifting a little the skin of the 

 thorax it is to be seen that the thorax of the imago before the wings is 

 blackish, perhaps dark greenish, on each side with a pale divergent band. 

 In fact the parts are similar to those of several Gomphoides. It was 

 stated that perhaps the n3-mpha may belong to Aphylla hrevipes, which 

 species has segment lOih as long as segment Dth, but this supposition is 

 rather improbable, since the nympha supposed to belong to A. producfa 

 was discovered I think it may belong to Cyclophylla. The abdomen of 

 the imago still in the abdomen of the nympha is pale with two dorsal 

 longitudinal blackish bands.

Three female nymphae in alcohol from Rio dos Macacos, Brazil, 



Thayer expedition. Length 31 to 35 mm. 



Not full grown; very similar to the specimen from Santa Cruz; differs by the 

 fourth joint of antennae stronger and longer; by the want of the trumpet-like 

 inflation for the insertion of antennae: by well developed dorsal hooks on 2 to 9' 

 the dorsal hook on segment 2 is a tubercle (just as in the other species), the third 

 strongest, all the other nearly equally developed. 



In comparing the two species perhaps some allowance is to be made 

 for the fact that the first species is just transforming. Perhaps the 

 shorter fourth joint of antennae and even the trumpet-like inflation may 

 be the consequence of the extraction of the antennae of the imago, for 

 the seta is to be seen in the third joint of the nympha. But as the 

 dorsal hooks are sharp, short, horny spines, they cannot disappear during 

 transformation. Therefore the three younger nymphae seem to belong 

 to a diff"erent species.

Two nympha skins, male and female, from Crescent City, Fla. Length 

 58 mm. ; breadth S mm. 



Body slender, very elongate, very little hairy ; head large, about as broad as the 

 body, cordate, deeply notched behind, eyes very large, globular behind : a polished 

 elongate spot before each of the posterior ocelli, four polished round spots on occi- 

 put, the two interiors smaller; antennae inserted in a trumpet-shaped inflation.
