PSYCHE. 



333 



Mexcala rufa, sp. nov. 



$■ Length S inm. Legs 4132, almost 

 equal in stoutness, femora slightly tiiickened. 



The cephalothorax is dark colored with a 

 few black hairs on the eye-region, and some 

 tiny white scale-like hairs on the front of the 

 falces, and the lower edge of the clypeus, 

 which pass around a little way, onto the sides 

 of the cephalic part. The legs and palpi are 

 black. The abdomen in our specimen, is 

 rubbed, but seems to have been entirely cov- 

 ered with golden-yellow hairs which shade to 

 white on the venter. 



We have one male from Cape Colony, 

 sent to us by Dr. Braun. 



QuEKETTiA, gen. nov. 



Tlie cephalothorax is rather low, and 

 i.s narrow in front, widening out behind 

 the third row of eyes and then contracting 

 behind. The upper surface is flat and 

 almost entirely on the same plane, there 

 being the gentlest possible rise from the 

 two ends to the dorsal eyes. It is a little 

 wider below than above. The quad- 

 rangle of the eyes is very slightly wider 

 than long, is wider behind than in front, 

 and occupies two-fifths of the cephalo- 

 thora.x. The anterior eyes are subtouch- 

 ing, in a straight row, the middle being 

 twice as large as the lateral. The second 

 row is much nearer the first than the third, 

 and the third row is not cjuite so wide as 

 the cephalothorax. The falces are very 

 short, vertical and parallel with no tooth 

 on the inferior margin. The sternum is 

 oval, truncated in front. The first coxae 

 are separated by a little more than the 

 width of the labium, which is as wide as 

 long. The pedicle is not visible from 



above. The relative length of the legs 

 is 4123, the first and second being short 

 and much thickened, especially as to the 

 femur and tibia. The type species is 

 6.5 mm. long. 



The short chubby front legs are 

 enough to distinguish Quekettia from 

 others of the group. The type is our 

 Leptorchcstcs georgii from Madagascar, 

 Ant-like Atfidae, p. 52. 



This genus is named for Mr. J. F. 

 Quekett, Curator of the Durban Mu- 

 seum, Natal, South Africa. 



KiMA gen. nov. 



The cephalothorax is long, and has the 

 sides nearly parallel. The cephalic part 

 is on a higher plane than the thoracic 

 which falls gently from the dorsal eyes. 

 The upper surface is narrow, the sides 

 widening out a very little below. The 

 quadrangle of the eyes occupies two- 

 fiflhs of the cephalothorax. is nearly as 

 long as wide, and is equall\ wide in 

 front and behind. The anterior eyes 

 are placed close together and form a 

 row that is a little curved downward, the 

 middle eyes being about twice as large 

 as the lateral. The second row is much 

 nearer the first than the third. The 

 third row is nearly as wide as the cephalo- 

 thorax. The falces are nearly horizontal, 

 divergent and rather long, with a short 

 fang, and have no tooth on the inferior 

 margin. The sternum is narrow and ob- 

 long, and is truncated in front. The first 

 coxae are separated by the width of the 

 labium, which is plainly longer than wide. 

 There is a distinct pedicle. In the type
