$ med. Closely resembles the maj., but differs in being 

 smaller, and in the sculpture of the head and thorax, but especially 

 of the latter, being much finer and closer, giving the whole 

 insect a much more opaque appearance ; the meranotal spines or 

 teeth are smaller and feebler. 



$ win. fiesembles the med., but is considerably smaller and 

 a little more shining, the very fine striation of the head seems 

 almost obsolete in certain lights. Thorax subopaque, metanotuni 

 transversely striate, metanotal teeth obsolete. 



$ . Of very large size, larger than the max., but resembling 

 it. Head finely longitudinally striate on the front, the striae 

 strongly divergent outwards above the vertex ; the head above and 

 the occiput covered with large shallow punctures over the stria3 ; 

 mandibles coarsely longitudinally striate and pubescent ; antennae 

 pubescent. Thorax : the pronotum transversely striate ; the 

 mesonotum, scutellum and abdomen smooth, polished, shining, 

 with a few scattered punctures ; metanotum and nodes of pedicel 

 coarsely transversely rugose ; legs very slender : wings brownish 

 hyaline. For the rest the characters of the genus. 



cJ. Head anteriorly irregularly sculptured and opaque, pos-

 punctures ; thorax on the sides, the metanotum and the nodes of 

 the pedicel more or less irregularly rugose, the remainder of the
