1/ (hitherto undescribed) . 2 - 8-3T mm. Head parallel-sided, vary- 

 ing from one-seventh to one-fourth wider than long. Eyes entirely 

 absent, or composed of four or five ill-defined facets. Mandibles not 

 striate at the base. Otherwise exactly like the type. 



§' . 1T-T4 mm. Epinotum, excepting the declivity, and sides of 

 the mesonotum reticulate and somewhat dull, the rest of the body 

 entirely smooth and shining. Erect pilosity very scanty, absent from 

 the legs and antennae, which have a feeble pubescence, wanting else- 

 where. Eyes composed of a single facet. Eirst joint of flagellum a 

 little more than twice as long as wide, about as long as the five 

 succeeding joints taken together ; 2nd-8th joints much wider than 

 long; the club not quite twice as long as the rest of the flagellum. 

 Mandibles quadridentate, smooth and shining, very sparsely and very 

 feebly punctured. The anterior angles of the pro-mesonotum sharply 

 defined, subdentate. Declivity of epinotum concave from above to 

 below, smooth and shining ; very distinctly margined at the sides, 

 the margin continued up to the epinotal teeth, and slightly beyond 

 them along the sides of the dorsum ; the dorsum longer than the de- 

 clivity, and one-third longer than wide. 



" Median area of clypeus subtruncate in front, which is not the case 

 in the type, . . . ; peduncle of the 1st joint of petiole short, shorter 

 than in the type " (Eorel). 



Two out of the three If. 1/ which I have before me were taken on 

 the same occasion. Both lack eyes. In one the head is one-fifth 

 longer than wide ; in the other one-quarter longer than wide. The 

 remaining If. has the head a little less than one-seventh longer than 

 wide ; but the eyes are distinct, though small. The ^ ^ of the two 

 series do not differ in the least, so that there is no reason to suppose 

 that the 1/ 1/ do not all belong to the same species.
