notched ; yellowish, paler than the head ; the other parts of the thorax 

 and the abdomen more or less dark fuscous, with i)aler articulations. 

 Legs fuscous, the articulations, the tarsi except of the front legs, and 

 beneath paler. Wings fuliginous, villous, with five longitudinal narrow 

 white bands ; sector bifid ; in the cell four to two transversals, and mostly 

 two between the costa and the end of the cell. Appendages fuscous, 

 stout, two jointed, of equal length, hairy; basal joint of left appendage 

 much thinner at base and strongly enlarged on tip internally ; basal joint 

 of right appendage stout, cylindrical. The last dorsal segment somewhat 

 cleft and deeply notched from the middle to the right side margin ; in this 

 place is inserted, with a largely inflated base, somewhat above the right 

 appendage, a brown spiniform process ; viewed from above the base is 

 membranaceous paler ; the process is horny, long, narrow (viewed from 

 sides, rounded on tip), bifid at base, going outside of the membranaceous 

 base, and sending the branch to the inner side ; the inner branch and the 

 process form a crescent, which is filled with a pale membrane, which on 

 tip goes outside upon the process and forms a small sharp tooth ; near the 

 left appendage is a similar horny process, but without an inflated base, 

 originating directly from the apical border of the segment ; this process is 

 shorter, a small lobe, similar to the other, ending (viewed from above) 

 knife-shaped ; between and beneath these processes is the last ventral 

 segment produced in a cone, turned to the left side, with a round open 

 aperture on tip. 



Mr. Lucas, 1. c, has given a very interesting note concerning the larvae 

 (?) and the habits of E. Latreillii. As Mr. Lucas, at the time of his 

 publication, could not have had knowledge of Mr. Wood-Mason's article, 

 it is still uncertain if the so-called larvee were really larvae or females. As 

 Mr. Lucas has not recorded the number of joints of the antennae, nor the 

 asymmetry or symmetry of the appendages, we should better wait to ex- 

 press an opinion till these gaps are filled. The size of the larva is just the 

 same as the male imago (8-10 mill.), therefore too small for a female, if 

 Mr. Wood-Mason's suggestion is correct. The last dorsal segment is said 

 to have a " petite fossette longitudinale," which would agree only with the 

 male. The detailed description of these larvae agrees well with E. La- 

 treillii., and as the author has found among them the winged (male) imago, 

 it will probably be that the described wingless forms were larvae of the 

 male. They were found by Mr. G. A. Foujade among the detritus of 

 Cycas sent from Madagascar to the Museum of Paris. Larva and imago
