spaces such as jungle paths, making a curious creaking sound. 

 The most brilHantly coloured species of moth I have seen on the 

 island is the Cossid Duomitus mineus, the cylindrical form, orange 

 colonr and bold greenish metallic markings of which give it a close 

 superficial resemblance when the wings are closed to a large Bup- 

 restid beetle.' A large yellow underwing (Ophiiisa corouata) was 

 sometimes abundant in the rains and developed the curious habit 

 of coming to drink out of our glasses at dinner. Tt was liy no 

 means teetotal in its tastes and we found that it could imbibe quite 

 an appreciable amount of iirand}- without apparent confusion. One 

 of the commonest moths in herliage is the cosmopolitan Dciopeia 

 fulchella. On the whole the moths of Barkuda are inconspicuously 

 coloured, and the exceptions I have mentioned stand out as 

 exceptions, to which but few names could be added. 



Arachnid Fauna. 



Dr. Gravely has discussed the spiders and scorpions of the 

 island in this instalment of my report. The latter are scarce and 

 only two species have been taken, .\inong the spiders perhaps 

 the most remarkable are the burrowing forms of the group 

 Mygalomorphae, several of which construct elaborate trap-door 

 nests in the earth at the base of fig-trees. Among the w?b-spinners 

 the absence of the large and conspicuous species of the genus 

 Nephila is a noteworthy feature. No Pedipalpi have been found 

 on Barkuda, notwithstanding diligent search on Dr. Gravely' s 

 part. 



Fauna of IMyriapgda. 



iMyriapoda are not very abundant, but representatives of 

 most of the Indian families of both centipedes and millipedes 

 occur. Among the former a large species of Scolopendra is not 

 uncommon, while specimens of Pseudocryptops agharkari, a small 

 species of the same family, described by Dr. Gravely from the 

 Bombay Ghats, have been taken. Dr. Gravely^ tells me that 

 they belong to the race singbhumcnsis which he described from 

 Chota Nagpur. Geophilidae are not uncommon among dead 

 leaves and under stones. Among the millipedes much the most 

 abundant is a Polydesmid. a species that wanders in the open in 

 fairly large numbers throughout the rainy season. Minute forms 

 of the family Poh'xenidae are fairly common under stones and in 

 the galleries of ants and termites, from the nests of which other 

 small millipedes have also been taken. 



Crustacean Fauna. 

 The only strictly terrestrial Crustacea observed on Barkuda 

 are land Isopods, and no freshwater species except small Knto- 



' I first observed the resemblance between this nioth and certain Buprestids 

 in the Malay Peninsula, where suitable "models" occur in (his group of beetles.
