liiiiiiK'i'iuiii a» k niolata n. sp. — Head and dorsulum opaque; parapsidal 

 furrows well impressed ; areola almost quadrate, a little wider than long; areo- 

 let petiolate. 



% Length 5 mm. Face indistinctly, finely sculptured, the silvery pubescence 

 not heavy, sculpture of front coarser, cheeks more shining. Parapsidal grooves 

 not clearly marked, more like a roughened impressed line, disappearing near 

 the middle of the dorsulum among the coarsest sculpture thereof, the sculpture 

 of the sides similar to that of the anterior one-third of the dorsulum, fine, indis- 

 tinct. Mesopleurse finely closely roughened, opaque on the lower half, less closely 

 sculptured and more shining above. Areola well defined, comparatively small ; 

 the lateral area divided by a distinct transverse carina extending across from 

 below the middle of the areola. The petiolar area extending from side to side at 

 the base. The surface of the metathorax rugulose. Wings transparent, with a 

 dark cast, nervures darker than the stigma, which is pale brown, second recur- 

 rent nervure received by the areolet at about the middle. The posterior half of 

 the petiole about twice as wide as the anterior half. 



Black. Trochanters of four anterior legs, part of anterior coxae and mandi- 

 bles, yellow, otherwise the four anterior legs are rufous; second trochanter of 

 posterior legs yellow, the femora ferruginous, apex of the second, a wide band 

 on apex of third, a wider band extending along the lateral margin of the third 

 dorsal segment somewhat orange-rufous; the fifth dorsal segment at apex, and 

 especially to the sides, brownish. The venter yellowish.

 taken to be identical with the description of L. flavicincta Ashm. 

 as far as it goes, it does not mention the sculpture of metathorax

 does differ in size and some slight color marking, and I believe it to 

 be distinct.
