Wings yellow; dorsulum subcarinate down middle; clypeus 

 broadly eraarginate or incurved, perpunctatus. 



Calicurgus pretiosus n. sp. 



9 • — Black ; tarsi somewhat testaceous ; thorax on sides, beneath 

 and on middle segment with dense silvery sericeous pile ; head wider 

 than thorax, transverse; clypeus transverse, finely punctured, ante- 

 riorly coarsely so, the fore margin a little incurved ; front micro- 

 scopically punctate, the impressed line reaching from base of antennae 

 half way to ocelli ; eyes strongly converging above, reaching base of 

 mandibles, separated above by a distance barely equalling length of 

 fourth antennal joint ; space between hind ocelli about equal to that 

 between them and eyes ; pronotum subangulate behind ; middle seg- 

 ment rounded, not impressed ; legs tolerably spinose, serration of 

 hind tibia? distinct, their longer spur almost equal to two-thirds the 

 length of first hind tarsal joint; abdomen subsessile, ventral seg- 

 ment with large, very sparse punctures ; wings subhy aline, the ante- 

 riors crossed by two dark fasciae, the outer of which by far the 

 larger, including the marginal, second and third submarginals, tip 

 of the second and most of the third discoidal cells ; second submar- 

 ginal cell rhomboidal, smaller than the third, receiving the recur- 

 rent vein in the middle, third submarginal narrowed fully one-half 

 above, and receives the recurrent vein before the middle. Length 

 12 mm.

Calicurgus cinereus n. sp. 



9. — Black; tarsi somewhat testaceous; thorax beneath and on 

 middle segment with silvery pile in certain lights ; head wider than 

 thorax, transverse, front impressed for its entire length, microscopic- 

 ally punctured ; clypeus rather large, apical half highly polished, 

 fore margin a little incurved; eyes reaching base of mandibles 

 strongly converging above, separated at the top by a distance scarcely 

 equal to length of fourth antennal joint ; antenna? long and slender ; 

 pronotum subangulate behind ; middle segment rounded, shining, 

 not impressed ; legs not strongly spinose, serration of hind tibiae dis- 

 tinct, their longer spur equal to more than half the length of first 

 hind tarsal joint ; abdomen subsessile, with sparse, pale pile ; wings 

 subhyaline, the anteriors crossed by two fuscous bands, the outer of 

 which the larger, and includes marginal except apex, tip of first sub- 

 marginal, second and third submarginals, entirely, and apical half
