 much dusted with white ; the spots of primaries repeated, and in 

 addition a spot in cell ; secondaries have a curved row passing 

 from near base on costal margin entirely around both margins, 

 ending at sub-median nervule ; eight spots in all, small white, 

 also a spot in cell.

ON THE PTEROGOSTIC AND OTHER CHARACTERS 

 OF EUCATERVA. 



By a. R. Grote. 



The male antennae of Encaterva Variaria are bipectinate, the 

 long ciliated branches diminishing in length gradually to the 

 tips. The stem is mostly covered on the outside by white scales, 

 and the branches also are tipped with white scales. The sim- 

 ple female antennae are nearly all black; they show an interspers- 

 ing of white scales, especially towards the base. The male labial 

 palpi are curved, stretched forward beyond the front, marked 

 with black and white scales ; the long second joint is twice 

 banded with black and white, the third article is tipped with 

 white, the black base corresponding with the black spots on the 

 second article. The female palpi are shorter, projected 

 more straightly forwards. The terminal article is tipped with 

 black. What is singular is that in the individual, which I am 

 disposed to believe is the typical ? , the palpi appear really 

 shorter than in the specimen which I regard as the variety. The 

 eyes are naked, ocelli wanting, the clypeus broad and rather full. 

 The tongue is apparently rudimentary, as in three specimens 

 which I have carefully examined I find no appearance of it. I 

 have not broken off the palpi, however, which may conceal it. 



I regard as the typical female the form in which the middle of 

 the primary is taken up by a deep black opaque shading, leaving 

 the costa and internal margin white. 



The variety wants this black broad stripe and is immaculate 

 white, black dotted, and reminding us of Cate7iaria. This variety 

 I call Labesaria, 



The abdomen, especially in the female, is somewhat clumsy 

 and vermiform. The scales are rather thinly laid on. The white 

 wings of the variety Labesaria are somewhat transparent. In 

 the male the front wings are thickly powdered with black over 

 the centre, and this black shading takes on vaguely the shape of 

 the black portion of the wing in the typical female. But the 

 most obvious difference between the sexes is the absence of the 

 two median lines of the male primaries above, in the two female 

 forms.
