22. Larger, circ. 13 mill. long. Abdomen finely 



punctured on a smooth shining ground, with

{ = niveo fasciatus, Dours). 

 Smaller, circ. 10 mill. long. Abdomen very 

 coarsely sculptured, with large rugose punc- 

 tures, and strong (CV/rcr/s-like) abrupt con- 

 strictions between the discs of the segments 13. ■punctatus, Mocsary. 



23. Third joint of antenna as long as the fourth. 



A small insect with short autenn;«, and very 

 short gense (their least length is not a fourth 

 of the width of the mandibles). Sixth 

 ventral plate with a pilose tuberculatiou 

 at each lateral angle and a wide pale apical 

 margin. Pedes postici with very slender 

 tibire and tarsi ... ... ... ... ... 23. brevicornia, Perez. 



Third joint of antenna evidently shorter than 

 the fom-th. Geme at least a third of the 

 width of the mandibles, often much more ... ... 24. 



24. Fifth ventral plate punctured (subrugosely) all 



over — the punctures seem both larger and 

 closer than those on the preceding segments. 

 Cordiform area of propodeum for the most 

 part longitudinally rugose, somewhat ob- 

 liquely 24. marcjinatus, Smith. 



Fifth ventral plate otherwise punctured 25. 



25. The disc of the fifth ventral plate {see PI. IX, 



51) is occupied by a large impunctate tri- 

 angidar space, nearly equilateral, whose 

 sides, defined by dark lines, converge from 

 the base of the segment to near its apex, 

 where the triangle ends in a small pale 

 rounded fovea. Outside this triangle the 

 surface is punctured and pilose. (A small 



Mongolian sp. circ. 8 mill, long.) 27- vcntralis,'Pexe7.. 



Fifth ventral plate sculptured otherwise 26. 



26. Sixth ventral plate (PI. IX, 49) with a rather 



conspicuous oval patch of dense dark-looking 

 pilosity bordered by an oblique fovea near 

 each of its lateral angles. Last dorsal 

 segment slightly incised at apex (sub-bilobate) 6. liyutus,'Ev. 

 Sixth ventral plate without conspicuous pilose 

 patches as above ; at most with a thin loose 

 tuft or pencil of pale hairs ... ... ... ... 27. 



27. The whole abdomen, including its basal segment, 



very closely, finely, and evenly punctured 

 above, so that the surface is uniformly almost 



dull 28. 



The puncturation is much less close and regular, 

 with shining intervals, on the basal segment 

 it is conspicuously larger and more sparse 

 than on those following ... ... 29. 



28. Slightly larger and especially broader than the 



next species, circ. 12 mill. long. Fasciaj 

 broad and yellowish. Hairs of thorax above 

 rich fulvous-red. Eyes very slightly con- 

 verging (Egypt) 4. ^je/'t'-(', n. sp. 



Fasciae somewhat narrower and snow-white. 

 Hairs of thorax above cinereous yellow. 

 Eyes rather strongly converging, making the 

 face look more triangular and the clj-peus 

 narrower (Algeria) ... ... ... ... 9. ctaoni, n. sp.
