DESCEIPTION OF A VARIETY OF T0M0GL08SA LUTEICORNIS, Er. 



BY MALCOLM CAMERON, M.B., E.N., F.E.S. 



TOMOGLOSSA LUTEICORNIS, V. EPPELSHEIMI, n. 



Entirely reddish-testaceous, except the anterior half or two-thirds of the 



elytra, which are more or less infiiscate, and a distinct dark patch on the 



middle of the sixth dorsal segment, not sharply circumscribed, but fading 



gradually into the ground colour. The fifth dorsal segment is sometimes also 



a little infuscate. 



This variety was referred to by Eppelslieim, in litt., as var. lasta, 

 but no description having appeared, and the insect being very distinct 

 from the type-form, I have thought it well to bring it forward and 

 dedicate it to the late Dr. Eppelslieim. 



Occurs not uncommonly in the Island of Kamaran in the Red 

 Sea, also, according to Eppelslieim, in the Caucasus.

ON SOME UNINTENTIONAL EVIDENCE IN SUPPORT OF THE 

 MIMICRY THEORIES, SUPPLIED BY A SMALL COLLECTION 

 OF BORNEAN BUTTERFLIES. 



BY J. C. MOULTOX, F.L.S., F.E.S., Curator of the Sarawak Museum. 



A collection of butterflies was recently brought to me for 

 examination by a friend who had caught them all in a fortnight's 

 visit to a Sarawak out-station (Simunjon, December, 1911) ; and as 

 it demonstrates so beautifully some of the chief characteristics of an 

 Eastern butterfly fauna, I have thought that perhaps a few notes may 

 be of some interest. ' Museum collections give a general idea of the 

 resources of a country in any particular faunistic branch, and entomo- 

 logical literatui'e can tell us something about the habits and rarity 

 (or otherwise) of each species, but a far clearer side-light on the 

 subject is gained by examining a small collection of this sort, formed, 

 I should add, by a non-entomological visitor, who was content to take 

 the easy course of collecting all those individuals which for the most 

 part seemed almost to court capture by their gentle flight and brilliant 

 colouring. An entomologist, recognizing the common species, would 

 probably have passed them by, and devoted his attention to the 

 rarities. This collection, however, was made by a rto?i-entomologist 

 to whom all Sarawak butterflies were new and desirable, and hence, 

 although there are no rarities which call for remark, the relative 

 numbers of each species are both instioictive and interesting.
