DEREIMA. Walker. 

 Derrima Henrietta {PhUomnia hcnricifd Grote). 



I h:ive seen in the British Museum Collection the type of Derrima 

 stellata. Wdlhrr. It is a female and closely resembles P. henrktta 

 with which it is congeneric. Mr. Walker places the genus as belong- 

 ing to the group of genera regarded as a Family under the name of 

 Acontidde. I am still of the opinion that the genus is allied to Anthoe- 

 cia and Heliothis. The squamation is rough and lustreless, not smooth 

 and lustrous as in Tarache {Acontiii) and its allies. From D. henrietta, 

 of which I have a very numerous series of both sexes, Mr. Walker's 

 D. stellata differs as follows : the fringes on both wings are long and 

 pink ; the secondaries above and both wings beneath are suffused with 

 pink ; the ocellate spots on the primaries above are a little larger, pure 

 white narrowly margined with black scales, not with suffused ferrugin- 

 ous borders (in which the lower spot is generally absorbed) as in D. 

 henrietta; the pink terminal space of the same wings is shaded with 

 yellow and the ground color of both wings beneath is yellow shaded 

 with pink on the borders; finally the narrow line, which defines the 

 pink terminal space inwardly, appears to be straight, not scalloped and 

 defined by white dots as in T>. henrietta. 



I have placed a specimen of D. henrietta in the British Museum 

 Collection. 



CALLEDAPTERYX (n. g. Phalaenidae). 



Head small; eyes globose and large; antennae short, simple, rather 

 stout and closely scaled. Labial palpi slight, divaricate, passing beyond 

 the front. Legs stout, smoothly scaled ; hind tibiae with two pair of 

 stout spurs, lower pair half the length of the tarsi. 



Wings with scalloped margin. Primaries with the costa rising and 

 slightly arched to the rounded apices ; below these the external mar- 

 gin is deeply and evenly semi-circularly cut out to extremity of first 

 median nervule, balow which point the margin retires straightly and 

 evenly inwardly obliquely to the exerted internal angle. Internal mar- 

 gin very sinuate, retiring inwardly behind the angle. Neuration : 

 Costal uervure simple ; subcostal nervure throwing off from its upper 

 side the first, second and third s. c. nervules on the margin, from a point 

 at about the middle of the wing : these nervules approximate and equi- 

 distant at base, 1 and 2 simple, 3 shortly furcate just before the mar- 

 gin ; fourth and fifth s. c. nervules thrown off together at the extremity 

 of the nervure ; fourth, furcate before the apex of the wing, the sixth 

 is simple, joining the external margin at the subapical excavation; a
