Early in May of this year I visited the locality tiirice, but without success until 

 the third time (May 9tli), when about forty specimens of the ^ and one ? were 

 obtained by sweeping the water plants that could be reached from the margin of 

 the pond, and one $ by beating the hawthorn hedge. 



In the British specimens of this species the antennse of the $ are much darker 

 than those of the ? , and the dark markings of the fore-wings are more strongly 

 developed in the greater number of the (J specimens, though some are almost 

 uniformly pale golden-brown, which is the condition of fully half of the ? . In 

 freshly killed S the posterior wings have the cilia and adjoining membrane some- 

 what rosy, but this is almost wholly lost in drying. The <? expands 12—14 mm., 

 the ? 16—18 mm. — J. E. Fletchek, Worcester : June, 1887.

Chrysopa stictonetira, Gerstdcker, = Nothochrysa insignis, Walker. — In the 

 " Mittheilungen des naturwissenschaftlichen Vereins fiir Neuvorpommern und 

 Riigen," xvi (1885), Dr. Gerstiicker described many new Australian forms of 

 Neuroptera-Planipennia {^= Meffaloptera), and gave a list of Australian species. 

 The descriptions are, as a rule, excellent, and I have had little difficulty in 

 identifying many species in my collection therefrom. But there are several notable 

 omissions of described species, and others described as new will fall as synonyms, 

 chiefly on account of the insufficiency of the original descriptions. 



With regard to Chrysopa stictoneura, I venture to think that Dr. Gerstacker 

 himself has erred in an essential point. The description agrees admirably with 

 Chrysopa insignis, Walker, which is a Nothochrysa, as I had indicated in Trans. 

 ]*;nt. Soc, London, 1808, p. 208. In fact, the character given for the third 

 cubital cellule in the anterior- wings, viz.," quergetheilt," is almost in itself sufficient 

 to prove this. But another essential character of Nothochrysa is that the labrum 

 should be more or less excised. Here, I believe. Dr. Gerstacker has slightly erred in 

 his description of sticionenra, for he says, " Oberlippe nicht ausgerandet," and 

 " labro truncato." The excision is only shallow, but, nevertheless, sufficiently con- 

 spicuous, and every other character most distinctly agrees with N. iusignis. More- 

 over the materials from which Dr. Gerstacker worked were mostly from the 

 Godeffroy Museum, and were for some time in my hands, and I remember to have 

 noticed N. insignis amongst them. Walker's type of C. insignis is given vaguely as 

 from " New Holland ;" Gerstacker's type of stictoneura is from Rockhampton ; I 

 possess two examples, one from Melbourne, collected by Mr. Henry Edwards, the 

 other from Sydney, collected by Mr. E. Meyrick. — R. McLachlan, Lewisham, 

 London : June, 1887. 



Hydroptila femoialis, Eaton, and H. longispina, McLach., probably only one 

 species. — This question mainly depends upon the very probable alteration in the 

 details of the anal parts of the g owing to drying, &c. The anal parts are simple. 

 The most prominent feature is a kind of conical or " boat-shaped " superior lobe. 

 Mr. Eaton (Trans. Ent. Soc. Lond., 1873, p. 137) terms it " trowel-shaped," and he 

 adds, "and there are two long setiform processes for penis-sheaths," but his figure
