This species is evidently closely related to the common Eurasian 

 L.fugax Lair., I>ut is certainly distinct. The female of the latter 

 species is considerably larger (4.7 6mm.), darker, with much less 



shining head, thorax, and pedicel, with the thorax almost as coarsely 

 punctate as the head, the epinotum more projecting, with very dis- 

 tinct base and declivity, a much shorter peduncle to the petiole, 

 shorter median funicular joints, darker wing venation, sparser and 



more bristly hairs. The male fugaz is also larger than the male 



soochowensis, much darker and more pilose, with the head, through 

 the eyes, broader than long, finely rugulose and subopaque. In size, 



sculpture, and color of the two sexes and in the shape of the female 

 epinotum and color of the wings the Chinese species is much more 

 like the common Nearctic N. iiiolc.sta Say, but the petiole and post- 

 petiole of the female molesta are very differently shaped, the thorax 

 is much narrower and more elongate, the pilosity is coarser, the head 

 of the male is more narrowed and less rounded behind and the an- 

 tennal scapes are decidedly shorter. 



14. Pheidologeton diversus (Jerdon). 



A soldier and female from Hong-kong (Terry) and two soldiers

 India, Burma, the Malayan Region and the Philippines. 



15. Pheidologeton 'affinis (Jerdon). 



Several soldiers and workers from Hong-kong (Terry). With 

 much the same distribution as the preceding species. 



16. Pheidologeton vespillo, sp. nov. 



Worker maxima (?). Length, 3.5 mm. 



Head rectangular, slightly longer than broad, with straight, parallel sides 

 and very feebly excised posterior border, evenly convex above and below in 

 profile. Eyes very small, flat, consisting of about 7-10 minute ommatidia, 

 situated about •§■ the distance from the anterior corners of the head. Mandi- 

 bles convex, with five blunt teeth, the two at the apex larger. Clypeus convex 

 in the middle, with a pair of blunt, anteriorly diverging ridges, narrow and 

 depressed on the sides, the anterior border sinuatcly notched in the middle. 

 Frontal area small and indistinct, at the anterior end of a small elongate 

 triangular impression. Frontal groove and carinae short, the latter diverging
