CATAULACUS. 123 



defined ; the lateral angles acutely dentate, the posterior lateral 

 angles of the head and the angle in front of the eye also acutely 

 dentate. Thorax : the pro-mesonotal shield broad, convex, the 

 pro-mesonotal suture obsolete ; the mesonotum narrowing poste- 

 riorly, the meso-metanotal suture visible but not very distinct ; 

 the basal portion of the metanotum horizontal, transverse, the 

 lateral metanotal spines not curved upwards; apical portion of 

 metanotum truncate, vertical, transversely coarsely striate ; legs 

 stout and short. Pedicel : the nodes more coarsely granulate and 

 rugose than the thorax, both anteriorly truncate, posteriorly 

 rounded, the 1st node somewhat broader than the 2nd ; abdomen 

 broadly oval. 



$ . Similar to the $ in colour, larger and altogether more 

 coarsely sculptured ; head and thorax very coarsely cribrate, 

 reticulate, with in certain lights the reticulations running into 

 irregular stria3 ; abdomen opaque but with a sericeous and, in 

 certain lights, a smooth appearance. Head as in the , but with 

 the ocelli indicated, sometimes nearly obsolete ; thorax in shape as 

 in C. lotus $ , but the metanotal spines smaller and more slender. 

 Pedicel with the 1st node oval, longer than broad, and distinctly 

 longer than the 2nd node, this latter constricted posteriorly ; 

 abdomen somewhat elongate, oval. 



Length, 4 ; $7 mm.

" . Intense black, opaque, densely punctured ; the scape of 

 the antennae and the tibiae reddish ; the head longitudinally 

 rugosely reticulate ; the sides of the head in front of the eyes and 

 the posterior angles with an acute tooth ; the pronotum in front 

 coarsely reticulate ; remainder of the thorax longitudinally rugose, 

 the sides furnished with little spines ; metanotum with thick 

 rugose spines ; the sloping portion of the metanotum somewhat 

 flat, densely punctured; the pedicel coarsely reticulate; the 1st 

 node obliquely truncate in front ; abdomen ovate, finely rugose, 

 for the most part longitudinally reticulate ; the back ot the femora 

 with obtuse little teeth ; the whole insect set with squarniform 

 scattered white hairs.
