either when at rest on wet sand, on which they settle with their 

 wings wide outstretched, or else buzzing rapidly backward^! and for- 

 wards near the hill-paths four or five feet above the ground and 

 looking more like an Aphiceus than a skipper. 



267. Odontoptilum angulata, Felder. 

 Taken in company with the preceding and again in July. 



268. Caprona alida, de Niceville, 

 Two males in the Upper Chindwiu in March. 



269. Caprona syrichthus, Felder. 



Two males at 1,500 feet in May. Females of this species are 

 extremely rare. There is a single specimen in the Phayre Museum, 

 Rangoon, and Mr. de Niceville informs me he has one from Moul- 

 mein. 



270. Caprona elwesii, n. sp. 



Three males at 1,500 feet and one in the Upper Chindwin, all taken 

 in May. 



I propose this name for the insect figured by Mr. Elwes in the Proc. 

 Zool. Soc. Lond., 1892, PI. xliii, fig. 2, as ^' C. syrichthus, var." 

 There seems to be no doubt that this is quite a distinct species, 

 the differences between it and C. syrichthus, though slight, are abso- 

 lutely constant, and the two species show no tendency to vary towards 

 one another. C. ehvesii is much the smaller. On the upperside of the 

 foreiving the basal spot in the submedian interspace is divided into 

 two ; on the upperside of the Idndwing the basal spot in the discoidal 

 cell is small and inconspicuous, while of the four discal spots which 

 are constantly present in true C. syrichthus only the one closing the 

 cell is present in C. eliuesii ; the underside of the for ewing is also 

 much more strongly suffused with grey in the latter. Both species 

 agree in habits with one another and with the species of Ctenoptilum 

 referred to above. Mr. Elwes records C. syrichthus from Bhamo, 

 the Shan Hills, and Java, and C. elwesii^ from Bhamo. I have obtained 

 males of C. elivesii in both the North and South Chin Hills, in the 

 Upper Chindwin District, and at Thayetmyo, in Lower Burma ; of 

 C. syrichthus 1 have only met with the two males recorded above. 



Mr. de Niceville informs me that his series of C. syrichthus are 

 quite constant and average a third larger than C. ehvesii, and in the 

 separation of which he" concurs.
