72 THE entomologist's record. 



In the European catalogue montiranHs is treated as a synonym of 

 tri:itis, which is of course incorrect. Murray, in his monograph on 

 the genus Catops, considered it to be a var. of tristis (although he also 

 called lonijulus and (/landicollis vars. of the same, which are now 

 regarded as good species), it may be as well to introduce it into onr 

 list as a var. at present. Mr. Bishop and I took a number of species 

 of Catops under this squirrel and he is noAv looking through his speci- 

 mens to see if there are more C. )iiontica(/iis. 



SCIENTIFIC NOTES AND OBSERVATIONS. 



Stray notes from Java. — The following notes may be of interest 

 to those studying mimicry : — (1) DnDif/d and Atlas Moth, April 30th, 

 1911, at Buitenzorg. — When in the gaidens one morning one of the 

 gardeners brought me a live Atlas moth, which was quite a foot in 

 expanse. I persuaded him to let it go, as I did not want it, and it 

 went oli" with a slow Happing flight for a few yards, when there was a 

 rush of wings directly behind me, and I saw it being carried oft' by a 

 drongo. The bird carried the moth in its claws to a high tree and tore 

 oft" portions of the wings preparatory to eating it ; but this took such a 

 time that I did not stay to witness the end of the tragedy. (2) Drvntjo 

 and />»^?t'/7///, May 26th, 1911, at Tjibodas. — When in the thick primeval 

 forest on the way to the Tjiborewa waterfall I was stalking a Zen.ridia 

 sp. ?, a large butterfly with a pale blue subapical band on the fore- 

 Aving. It flew oft" the underside of the leaf on which it was settled 

 and was immediately darted at by a drongo, which seemed to come 

 from nowhere ! The bird did not capture it, and did not repeat the 

 attack. In this thick forest the butterfly was almost invisible, except 

 for the blue bar, which is bluish white in the female. The wings of 

 the fresh male are of a deep indigo blue, a lovely colour, which, like 

 that of the nisco/i/tora celinde, will probably fade ; the female is deep 

 brown, with large bluish eye-like spots on the hindwings ; these are 

 smaller and more obscure in the male. Some would consider this 

 blue band a directing mark. It always settles on the underside of a 

 leaf, about five feet from the ground, but frequently high up out of 

 reach and always with widely expanded wings. (3) Clcromc arcesilaus. 

 This obscure, uniformly-coloured, brownish-yellow butterfly was very 

 common in this forest, it is in fact, in every thick forest; it settles on 

 the path, and when disturbed flutters into the jungle. It is difficult to 

 see in such deep shade, but is easy to capture, as it has a very weak 

 flight. Out of the numbers I have seen, none had pieces taken out 

 of their wings, though many were very ragged. (4) Piioneris 

 resembling Delias, May 24th, 1911, Poentjah Pass, West Java. 

 — Captured a male /V/()»(;/.s ///(«7o?k;»/<', Bsd., which closely resembles 

 a hclias by its yellow hindwing and red costa ; but the flight is quite 

 different, being less floating and more rapid and darting. It is rare in 

 Java, but />. bdisaina, which would be considered its model is very 

 abundant. This is a similar ca.se to /*. sita and P. nicltaris in South 

 India and Ceylon. (f)) Mrlanitis isnifnr, October 27th, 1911, Padang 

 (on the equator), Sumatra. — T found one specimen, which was inter- 

 mediate between the wet and dry season form ; a few days afterwards 

 at Buitenzorg the wet forms were common but very worn, and the
