LEPTORCHESTES GEOEGIUS N. SP. 



PL IV., Fig. 6, epigynum. 

 9 . Total length, 6.5 mm. 



Cephalothorax : Length, 2.5 mm.; width, 1.7 mm. 



Legs, 4123 ; first and second pairs plainly .stoutest. 



4th leg longer than third by tarsus and metatarsus. 



Cephalothorax low and flat, very narrow in front, round- 

 ing out behind the dorsal eyes. Cephalic and thoracic parts on 

 the same plane, not separated by a depression ; thoracic part 

 not falling until near posterior margin. Quadrangle of eyes 

 very slightly wider than long, wider behind than in front, 

 occupying nearly one-half cephalothorax. Anterior eyes in a 

 straight row, subtouching ; middle twice as large as lateral. 

 Clypeus one-fourth as high as middle eyes. Second row much 

 nearer first than third row. Third row not quite so wide as 

 cephalothorax at that place. Falces short, vertical, parallel 

 and weak. Lip as wide as long. Coxae i separated by a little 

 more than the width of the lip. Sternum oval, truncated in 

 front. Pedicle not visible from above. 



Color. Cephalothorax black, with some dark hairs around 

 the anterior eyes. Abdomen blackish, showing, in our some- 

 what damaged specimen, a spot of white hairs on each side of the 

 dorsum, behind the middle, and traces of white hairs on other 

 jmrts. Legs, palpi, falces and entire under surface, dark brown. 



L. georgius is less ant-like, both in form and in color, than 

 chrysopogon, mutilloides and berolinensis. The cephalothorax 

 is much Avider behind the dorsal eyes than at the anterior row, 

 and the abdomen has neither the constriction that is found in 

 chrysopogon and mutilloides, nor the pure white, transverse 

 band which, in all three of the other species, marks oflf the 

 abdomen into two parts. Moreover, the under surfaces of 

 chrysopogon, mutilloides and berolinensis are strikingly alike, 

 having the sternum and the coxse of the third pair of legs black, 

 and the coxee of the first, second and fourth pairs pale ; while in 

 this species the sternum and all the coxte are uniform brown. 



Habitat. Madagascar.
