Cameeon. — On Hymenoptera. Ill 



Antennae brownish in the middle beneath ; the scape 

 punctured, covered with white hair. Head shining ; the 

 raised part of the face closely and strongly, the sides more 

 sparsely, punctured; the clypeus with scattered punctures; 

 both parts are rather thickly covered with brownish-fuscous 

 hair. Mandibles black, broadly reddish in the middle. Palpi 

 dark-testaceous; the basal joints blackish. Thorax black; 

 pro- and meso-notum closely and distinctly punctured ; the 

 latter, especially at the base, thickly covered with brownish 

 pubescence. Scutellum with scattered punctures above ; the 

 lower half of the sides closely and distinctly punctured. Post- 

 scutellum more closely punctured and more thickly haired ; 

 its sides stoutly keeled. The basal area3 on the median seg- 

 ment striated strongly, at the apex irregularly punctured ; the 

 striae on the middle area transverse, on the lateral more 

 oblique ; the supramedian area slightly broader than long, of 

 equal width throughout ; the posterior median area is closely 

 transversely striated, the striae running into irregular reticu- 

 lations ; the outer areas are more coarsely reticulated. Pro- 

 pleurae closely punctured, more sparsely at the apex than at 

 the base. Mesopleurae closely punctured, but not so closely 

 as the propleurae, and more strongly ; the apex depressed ; the 

 depression with stout keels. Metapleurae closely and rather 

 strongly punctured ; the middle with fine longitudinal stria- 

 tums. Sternum closely punctured. Legs red ; the coxae, 

 trochanters, and the apex of the binder femora black. Wings 

 hyaline, with a slight fulvous tinge ; the costa and stigma 

 fulvous ; the nervures darker. Abdomen shining, black ; the 

 second segment entirely rufous ; the first petiole finely longi- 

 tudinally striated ; the second segment finely and closely 

 punctured ; gastracoeli large, shallow, at the base indistinctly 

 striated ; the apical segments are thickly covered with black 

 hairs. 



Degithina, gen. nov. 



2 . Abdomen with eight dorsal segments, the apex rather 

 bluntly pointed. Antennae longish, not distinctly involute ; 

 the joints of the flagellum twice longer than broad ; the 

 apical slightly compressed and dilated. Upper tooth of man- 

 dibles much larger than lower. Clypeus separated from the 

 face. Head largely developed and obliquely narrowed behind 

 the eyes ; the occiput sharply margined. Labrum projecting. 

 Scutellum large, flat or slightly prominent. Post-scutellum 

 depressed laterally at the base. Median segment distinctly 

 areolated ; the apex with an oblique, straight slope, clearly 

 separated at the top from the basal part ; the supramedian 

 area large, widely separated from the base of the segment, 

 and reaching to the apex of the slope. Spiracles large, linear.
