Descrihod from a sin^li* spcciiiicii taken on Ml. Matan^', West

 There is also a worki'r from Knelling l.lolm Hewitt) in my eolh-etion. 



I have deserihed the feniah- in (U-tail on account of its interest in 

 coniuftion with Emery's contention (in Sarasin and Roux, Nova 

 Caledonia. Zool., 1014, 1, p. 407 tioitt) that rufiniitri,t is really a 

 Monomoriinn, mainly hecatiso the worker is .smooth and shininj; an<l 

 has a slightly j^edtinculate ])etiole. Althotij,di my specimen is not 

 accompanied hy workers, Ford's recent discovery (Tijdschr. eiit., 

 1915, 68, p. 23) of all three phases of a new variety of this ant, var. 

 slmalurnna from Simahir, a small island off the west coast of Sumatra, 

 shows that the Bornean female must hclon^ to the typical rufirintrin 

 or one of its varieties. The worker niinalurntm varies from 3-7.9 mm. 

 in length, the female measures 12-12.') mm. and the male only 4.4 mm. 

 These extraordinary differences in stature are comparable to those 

 previously noted by Forel (Philippine joum. sci., 1910, 5, p. 12.")) in 

 I'. olAonga subsp. dispar, the worker of which measures 8.2 nun., the 

 female 8 mm., the male 3.8 mm. Certainly the female of w hat I take 

 to be the typical rufivcntris described above and that of the var. 

 simaluratm, which is merely somewhat larger and very slightly differ- 

 ent in other respects, must be regarded as belonging to \'ollenhovia. 

 It is, moreover, closely related to V. striatopuuctata Mayr, known 

 only from the female (9-10 mm. long), and considered by Emery as 

 probably the female of V. oblonga subsp. laivithor(u- Emery (lor. cit., 

 p. 40(j). In some species and subspecies of \'ollenhovia, however, 

 the female is only slightly larger than the worker, e.g., in 1'. emcryi 

 Wheeler of Japan and in a Bornean subspecies of V. hanksi Forel 

 described below.
