Figure 5 is the labium of an undescribed fragment of a nym- 

 phal moult, found in the bottom of a bottle with other speci- 

 mens that were labeled "Tapajos River, Brazil, 1885." There 

 was hardly more than the labium present, and nothing fit for 

 description save the labium, but that is of so remarkable form, 

 that it is worthy to be made known even though at present un- 

 identifiable. Clearly it is allied with Cyclophylla by the form 

 of the median lobe, but the sigmoid-uncinate end hooks of the 

 lateral labial lobes are without a parallel among described 

 forms. 



Fig. 6 represents the labium of Hagen's Gomphus No. 14 (1. 

 c, p. 262). It comes from Cairo, 111., and has since been rede- 

 scribed in Bull. 111. State Lab. Nat. Hist. vol. 6, p. 82, 1901. 

 It is clearly a Gomphus, and is chiefly interesting tor the differ^ 

 ences shown by the labium from other known members of that 

 genus. The sharp straight end hook is set at a right angle with 

 the body of the lobe, and close up under it are two or three 

 teeth on the inner margin. It remains specifically undetermin- 

 able. 



Figure 7 represents the labium of Onychogoinphus Uneatus. 

 raised by Rev. M. M. Carleton, at Delhi, India, and determined 

 by Hagen.. The labium is much like the labia of the closely al- 

 lied and better known nymphs of Ophiogomphiis and Herpeto- 

 gomphus in having the middle lobe broadly rounded and the 

 lateral lobes blunt and not pointed on the ends, but the terminal 

 third of the lateral lobe is slenderer in Onychogomphus than 

 in the other two genera. 



Figure 8 represents the labium of an undetermined species 

 of Ictinus from Middle Himalaya, India. Hagen had no doubt 

 of the identity of the genus, nor have I, though there is no ve- 

 national evidence to prove it. The labium is remarkably short 

 and broad, the lateral lobes are pointed and serrate-toothed 

 within, and the rounded middle lobe is fringed with a series of 

 spines so remarkable in form that I have represented a few of 

 them enlarged in figure 9. 



A word or two may be added concerning the identity of two 

 other nymphs described by Hagen. His Gomphus No. 2 (1. c.
