13 . Cremastogaster sordidula Nylander var. osakensis Forel. 



FoREi., Bull. Soc. Ent. Suisse, X, 7, 1900, p. 269, ^ 



Several workers collected by Mr. Hans Sauter at Kanagawa agree 

 with Forel's description of this yellow form of the palearctic sor- 

 diditla. The types are from Osaka, as the name indicates.

 F. Smith, Trans. Ent. Soc. London, 1874, p. 407, ^ 



The types of this inadequately described species are from Hiogo.

Described by Forel from Sapporo in the island of Yezo. It seemed 

 certain to him that his specimens, coming from a locality so far from 

 Hiogo, must represent a distinct variety. I find however that a 

 number of workers collected by Hans Sauter at Kanagawa and 

 Yamanaka agree perfectly with Forel's description of the variety 

 matsumurai though these localities are in southern Japan near Hiogo. 

 It is probable, therefore, that the characters which Forel regards as 

 varietal are merely omitted in Smith's brief and slipshod description. 



A dealated female from Yamanaka, Suruga, is 6 mm. long, dark 

 brown, with yellowish mandibles, legs and antennae. Body smooth 

 and shining, very sparsely and finely punctate; anterior half of head 

 subopaque, finely and longitudinally striated. Head broader than 

 long. Epinotal spines very short, stout and blunt. Petiole and 

 postpetiole similar to thoge of the worker, the latter segment with a 

 faint median depression. 



According to a note accompanying the specimens, this ant lives 

 "in small colonies under the bark of pines and Cryptomerias. " 



16. VoUenhovia emeryi sp. nov. 



Worker. (Plate XLI, Figs. 10 and 11.) Length 2-2.3 mm. 



Head longer than broad, rectangular, with straight, subparallel sides and 

 broadly concave posterior border. Eyes rather large, in front of the middle of 

 the head. Mandibles with 5 graduated teeth. Clypeus short, with transverse 

 anterior border, not produced in the middle, and with two longitudinal, rather 

 thick ridges, diverging anteriorly and separated by a depression. Antennae 

 12-jointed; scape short, swollen distally, its tip reaching half the distance
