THE HETEROCERA OF SIKHIM AND BHUTAN. 321 



Genus Micronia, Guen. 

 3027. M. aculeata, Guen. 

 Sikhim and Bhutan, 1,800—6,000 feet. This is the commonest 

 insect of the family and may be taken at light or by beating low 

 jungle from March to October. The striations on the forewings of 

 different specimens vary in extent considerably. ( A specimen from 

 British Bhutan in February is one-third smaller in size than the 

 average. — H. J. E.) 



Genus Chatamla, Moore. 

 3028. C. flavescens, Wlk. 

 Sikhim and Bhutan, 4,500 — 6,000 feet. I have only two specimens 

 of this brought in by my collectors from Nim and Lingtu in British 

 Bhutan ; they are dated April and August. ( A rare species of which I 

 have 2$ and 19. The figure in moths of India, Vol. III., p. 118, 

 marked $ is, I think, certainly a $ . Both my males, which differ 

 much from each other in colour, have pectmated antennae and are 

 smaller than the $. — H. J. E.) 



Genus Auzea, Wlk. 



3029. A. rufifrontata,) Wlk. 



Sikhim and Bhutan. Brought in by my collectors, dated April and 



June. I know nothing of the elevation at which it occurs. ( I took 



it at Mongpoo at about 4,000 feet on May 25th, but it is not a common 



species. — H. J. E.) 



3030. A. arenosa, Butl. 

 Sikhim, 5,500 feet. I took one specimen of this at Tukvar at light 

 in April 1889, but have not seen another since. (I have four from 

 Sikhim and two from the Naga Hills, which are much greyer in colour 

 than those from Sikhim. — H. J. E.) 



3031. A. hyperthyra, Hmpsn. 



Sikhim. I do not know this species, (A very distinct species of 

 which the unique type is in my collection. — H. J. E.) 



3032. A. torridaria, Moore. 



Bengal ( fide Hampson). As the species of the genus seem to 

 be confined to the hilly portions of India it is probable that the 

 present species, if it occurs in Bengal at all, will bo found in the 

 Sikhim and Bhutan Hills. I have one male from Kanara, which 

 has a hyaline streak below the origin of vein 5 of the hindwing, 

 which feature does not appear to be present in the female ( vide 

 description).
