well-defined tooth near the middle. Comb of fore metatarsus 

 almost obsolete. 



Hab. Mabira Forest, Uganda (6\ G. Gowdey), July 1913. 



This is a true Motes, not one of the croesus group of 

 Notogonia. 



Tachysplie.v fulvicornis, sp. n. 



$ . Nigra ; mandibulis, apice excepto, clypeo dimidio apicali, an- 

 tennis, tibiisque tarsisque anticis fulvo-ferrugineis ; alis hyaliuis, 

 veuis fusco-ferrugineis. 



Long. 7 mm. 



? . Clypeus short, broadly truncate at the apex, the ante- 

 rior margin strongly depressed. Head and thorax closely and 

 very delicately punctured-rugulose; antennae slender ; second 

 and third joints of the flagellum equal, each twice as long as 

 the first joint. Eyes separated on the vertex by a distance 

 slightly exceeding the combined length of the two basal 

 joints of the flagellum. Thorax opaque ; pronotum oblique, 

 showing a distinct transverse dorsal surface, which is only 

 slightly below the level of the mesonotum. Median segment 

 much broader than long, abruptly truncate posteriorly ; the 

 dorsal surface coarsely longitudinally rugose-striate in the 

 middle, finely punctured-rugulose on the sides; the apical 

 slope finely and closely punctured, with a deep median 

 groove ; the sides of the segment obliquely striated. Abdo- 

 men finely shagreened ; the two basal tergites with transverse 

 spots of white pubescence at the apical angles ; pygidial area 

 elongate-triangular, slightly convex, finely and closely punc- 

 tured. Comb of the fore tarsi long and slender ; tarsi not 

 unusually short, the fourth joint longer than broad. Wings 

 rather short, the radial cell broadly truncate at the apex ; 

 third abscissa of the radius twice as long as the second, third 

 cubital cell less than half as long again on the cubitus as on 

 the radius. 



Ihib. Chapra, Bihar (Mackenzie). 



Easily distinguished from other black Tachysphex by the 

 colour of the antenna?, the sculpture of the median segment, 

 and the dull opaque surface of the whole insect. 



Trypoxylon jletcheri, sp. n. 



$ . Nigra ; abdomine rufo-ferrugineo ; trochanteribus posticis, 

 femoribus posticis dimidio basali, tibiis supra nigro-suffusis, 

 tarsisque anticis intermediisque fei rugineo-testaceis ; alis hyalinis, 

 iridescentibus, venis fuscis.
