PSYCHE. 



[April, igo2 



and is a very little wider behind than in 

 front. The first row is curved downward, 

 the eyes being small, and all separated, 

 the lateral by nearly their diameter from 

 the middle. The middle eyes are less 

 than twice as large as the lateral. The 

 second row is a little nearer the first than 

 the third, and the third is nearly as wide 

 as the cephalothorax. The fakes are 

 vertical, long, heavy, and parallel, with 

 a short fang. There is one conical tooth 

 on the inferior margin. The sternum is 

 oblong, narrowing in front and behind 

 and truncated in front. The first coxae 

 are separated by about the width of the 

 labium, which is longer than wide. 



The eyes of this genus resemble those 

 of Euryattus and Si?naet/m, but these 

 genera belong respectively to the Pluri- 

 dentati and the Fissidentati. Moreover 

 the joints of the palpus are differently 

 formed and proportioned, being flattened, 

 with the tibia much longer than the tar- 

 sus, in Euryattus and Sitnaetha. 



The type is a new species from 

 Mashonaland. 



Jasoda woodii, sp. nov. 



$■ Length 7 mm. Legs 134-, not slen- 

 der, nearly equal in thickness. 



In our single specimen the cephalothorax 

 and abdomen are both rubbed so that no idea 

 of the marking can be formed. The cephalo- 

 thorax is dark, almost black, with violet re- 

 flections. The abdomen is also dark but not 

 glistening, and shows some long white hairs 

 at the anterior end and on the sides. There 

 are some long whitish hairs on the falces at 

 the lower outer coiner. The legs are light 

 brown with slender black spines. The palpi 

 are covered with white hairs. 



We have one male sent to us by Mr. 

 Guy A. K. Marshall, from Mashonaland, 

 South Africa. 



Mexcala, gen. nov. 



The cephalothora.x is moderately high. 

 It widens out more below than above, 

 and is broader in the posterior part than 

 in front. There is no marked difference 

 in the planes of the cephalic and thoracic 

 parts. The cephalic part is flat, and 

 the thoracic falls from the dorsal eyes. 

 The quadrangle of the eyes occupies a 

 little more than one-third of the cephalo- 

 thorax, is one-sixth wider than long, and 

 is equally wide in front and behind. 

 The anterior eyes are moderately large, 

 the middle being less than twice as large 

 as the lateral, and form a slightly curved 

 row. The middle eyes are subtouching, 

 with the lateral a little separated from 

 them. The second row is halfway be- 

 tween the other two. The third row is 

 a little narrower than the cephalothorax. 

 The falces are vertical and stout, with 

 a short fang, and have one conical tooth 

 on the inferior margin. The sternum 

 is oval, and truncated in front. The 

 first coxae are separated by about the 

 width of the labium, which is longer than 

 wide. The pedicle is not visible. There 

 are no constrictions. The abdomen is 

 narrow in front and then widens. 



Mexcala is distinguished from the 

 other ant-like genera of this region by 

 having a single conical tooth on the 

 inferior margin of the falx.
