364 hili-ktin: miseim of comparative zoology. 



Descrihrd from imiiu'nnis workrrs that Avore travelling across a 

 path. 



Workers were kindly compared by Professor Emery with cotypes, 

 who writes that they are identical with the smaller workers of dimor- 

 phus, though the largest of the type lot is much longer (9 mm.) than 

 anv that I found.

An abundant species, nesting beneath stones, logs, or bark, or in 

 little shelters made of vegetable debris on leaves. It is fond of 

 attending scales. One nest sheltered two pupae of a myrmecophilous 

 fly, (Bardistopus sp. nov.) from which I reared adults. 



Camponotinae. 



93. AcROPYGA (Acropyga) moluccana Mayr, subsp. 

 PAPUANA, subsp. nov. 



Worker. Length 2.5-2.75 mm. 



Differing from typical molitccana as figured by Emery (Ann. Mus. civ. stor. 

 nat. Geneva, 1900, 40, p. 698, fig. 13a) only in the shape of the head, which 

 has the sides much less convex, more as in crassicornis Emery, but differing 

 from the latter in having occipital border concave and the penultimate anten- 

 nal joint a little longer than broad, instead of transverse. The tegument is 

 feebly shining. The color is brownish yellow. 



I'gi: Pawa (Type-locality). Malaita: Auki. San Cristoval: 

 Wainoni Bay, Star Harbor. Ysabel: P^ulakora. 



A very common species, found in populous colonies beneath stones or 

 logs. Type.— M. C. Z. 9,182.
