much smaller, rounder, and not nearly so elongated, and 

 by the dorsal segments not being longitudinally striated. 

 Characteristic is the fact that the longitudinal keels on the 

 metanotum are obsolete, and, on the other hand, there are 

 transverse ones, as in the Cryptina. The mandibles are 

 peculiar ; they are broad at the base, project largely down- 

 wards below the head, and appear as il: they were attached 

 by the upper part only and not by the whole width of the 

 base. 



The differences between Imeria, Xenojoppa, and Habro. 

 joppa may be shown thus : — 



A. Abdomen with seven dorsal segments, the meso- 



notum coarsely reticulated, mandibles and fore 

 coxse normal. 

 Postpetiole widely dilated at the apex as iu the 

 Flatyuri, clearly separated, the hinder coxae 



toothed ' Xknojoppa. 



Postpetiole not widely dilated, not clearly separated 



from the petiole, the hinder coxte not toothed . Habrojoppa. 



B. Abdomen vsith eight dorsal segments. Mandibles 



very broad,thick, and developed straight downwards 

 at the base ; the fore coxse large, globular, laro-ely 

 developed behind the base of the trochanters ; 

 the mesonotum not reiiculated Imeria. 



Imeria albomaculata, sp. n. 

 Black, shining; a line, broad and oblique on the top, 

 gradually narrowed towards the apex, on the inner, a some- 

 what oblong one on the outer orbits^ not reaching to the 

 bottom of the eyes, a mark, broadly, triangularly dilated on 

 the outer side beneath, on the outer lower orbits, the clypeus 

 except a small black mark in the middle above, the mandibles 

 except the teeth, the palpi, the base of the pronotum, the 

 yellow continued more narrowly to the end of the pleurae, 

 a short line on the sides in front of the tegulse, tubercles, 

 an irregular somewhat triangular mark on the lower side 

 of the mesopleurae, at the apex, the scutellum, post- 

 scutellum, a large triangular mark on the side of the 

 median segment before the spiracles, the apex of the median 

 segment, following the outlines of the arese, thus being 

 somewhat triangular above, and laterally on the lower side 

 continued into the spiracular area immediately over the 

 coxse, yellow. Wings hyaline, the stigma testaceous, the 

 uervures darker. The four anterior legs rufo-fulvous, with 

 their coxse and trochanters white; the hinder coxae black, 

 their apical three fourths white above ; the hinder tro- 

 v^hanters and femora rufo-fulvous ; the basal joint of the
