112 Mr. Butler's notes on the species of 



to four and occasionally five, the anterior coxae are 

 either snow-white or metallic green (in specimens from 

 the same island) ; the basal segment of the abdomen is 

 either wholly green, or has the centre black, or has the 

 sides opaline whitish and the centre brownish orange ; 

 grades between these variations also occur, proving 

 that they have, in this species, no specific value ; the 

 black bands across the carmine also vary in width. We 

 have a series of twenty-one examples in the collection 

 from Australia, Ke Island, the New Hebrides, Lizard 

 Island, Treasury Island, Pentecost, Guadalcanar, Alu 

 and Malayta, of the Solomon group. 



To this section of the genus belongs the Glaucopis 

 paula of Eober, from East Celebes, a small species 

 apparently allied to E. ccelipennis, but unknown to me. 

 It is possible that E. cincta, of Montrouzier, may also 

 come into this section, but the secondaries are described 

 as having four yellow spots upon them, an entirely new 

 feature among the hyaline winged species. 



The following are species in which the primaries and 

 nearly the whole or sometimes the whole of the second- 

 aries are opaque. 



11. Euchromia lethe, Fabricius. 



This is the Sphinx eumolphus of Cramer, and was con- 

 founded by Walker with the following very distinct 

 species under the name of E. sperchius ; it is a common 

 S. African species, and we have it from Natal, the Cape, 

 and Madagascar. 



12. Euchromia fulvida, n. s. (PI. IV., fig. 5). 

 The West African representative of the preceding, and equally 

 common ; it differs in having the pale patches on the wings deep 

 fulvous instead of sulphur-yellow ; the metallic markings less blue, 

 and the fifth segment of the abdomen pearly greenish-white 

 instead of metallic green like the posterior segments ; the anterior 

 coxae metallic green instead of pure white. Expanse of wings, 

 45 54 mm. 



Thirteen examples, from the Congo, Angola, Sierra 

 Leone, &c., are in the Museum series.
