[March, 



before me); those of tlie V darker tluiii the labial palpi, whieh are yellowish in 

 both sexes. Legs testaceous, but partly fuscesceiit; eoxie fuseous. Anal parts 

 yellowish. 



Wings with the ncuration similar to that of C. irrorata ; iridescent; fore-wings 

 with blackish pubescence ; long silky fringes of the hind-wings more greyish. 



In the 3 the anal parts consist of a large broad dorsal plate, the posterior part 

 of which is narrower than the basal, and the hind angles are each provided with two 

 strong spines ; seen from above the breadth of the posterior part of the plate and 



the position of the 

 spines vary a little 

 from the results of 

 drying. From be- 

 2- neath this plate 

 escapes the large 

 down - turned penis, 

 which, seen from 

 above, seems to have 

 two approximated 

 piceous ridges which 

 open in front, causing 

 the apex to appear 

 excised. The inferior 

 appendages are large 

 and prominent; view- 

 ed from beneath they 

 consist of a basal part 

 which has towards its 

 inner margin a more 



strongly chitinized band, which seems to be turned abruptly outwards ; after nar- 

 rowing slightly they turn outwards into a large foliaceous expansion, the hind 

 margin of which is excised, and the outer portion of this expansion is in turn 

 recurved towards the abdomen. From the inner angle, or lobe, of the excised hind 

 margin, viewed from above, springs a long and strong spine directed outwards, and 

 from the outer margin of (he foliaceous expansion arises a much smaller spine 

 directed forwards. 



The $ has the anal parts very much as in C. irrorata. 

 Expanse of wings, IH — 13 mm. 



Compared with C. irrornia this new species is an altogether 

 much darker looking insect, and the golden pubescence of the former 

 insect is entirely absent. The costal fringe seems also to be less 

 dense than in irrorata, and so do the pubescence of the membrane 

 and the hairs of the basal joint of the antennse, but the material is not 

 in a condition so perfect as are the examples of irrorata used in com- 

 parison.
