ami Ht'th finely and closely punctured ; sixth dorsal sep^ment 

 nioi'e distinctly punctured, rather broadly rounded at the 

 apex, tlie pys^idial area distinct but without stronoly raised 

 sides. Basal joint of the fore tarsus with seven long spines. 

 Second abscis:?a of the radius much shorter than the first ; 

 tlie curvature of tiie first transverse cubital nervure very 

 distinct. 



Hah. Gambia {Simpson) , March. 



This is not the female o( ferrugineics, Sin., which occurs in 

 the same locality. That species was described from a male 

 in which the first transverse cubital nervure is straight ; the 

 female of ferrugineus is very similar in colour to rubruflavas, 

 but has the mesonotum black and has a median depression on 

 the scutellum, the clypeus is not deflexed from the middle and 

 is more sparsely punctured, and the puncturation of the 

 thorax and abdomen, though fine, is much more distinct than 

 in ruhrojlavus. Both species are on the wing in March. 



Stizus aurijluus, sp. n. 



5> . Nigra ; clypeo, labro, maudibulis basi, fronte sub antennis, 

 jironoto margine posteriore, segmonto dorsali i)rimo macula trans- 

 versa utrinque, segmentis dorsalibus 2-5 fascia lata interrupta 

 flavis ; capite, antennis, pronoto, mesonoto lateribus, scuLello, 

 segmento mediano, pygidio pedibusque ferrugineis ; pygidio apice 

 dense aureo-sericeo ; alls hyaliuis, venis fuscis ; costa late 

 infuscata. 



Long. 25 mm. 



? . Clypeus broadly emarginate, the emargination slightly 

 angular in the middle ; inner margin of the eyes almost 

 parallel; apical joint of the antennae conical, as long as the 

 ])enultimate. Thorax finely and very closely punctured, 

 scutellum without a median depression ; pubescence long and 

 greyish, more dense on the median segment than elsewhere. 

 Abdomen closely and very distinctly punctured ; sixth dorsal 

 segment more closely punctured, clothed with ferruginous 

 pubescence at the base, with shining golden pubescence at the 

 apex, with a well-marked pygidial area, very broadly rounded 

 at the apex. Basal joint of the fore tarsi with eight stout 

 but not very long spines. Second abscissa of the radius 

 shorter than the first ; the costa thickened and forming a 

 very distinct rounded stigma at the base of the radial cell.

This is very near chri/sorrhceus, Handl., but differs from 

 S. -African specimens sent by Dr. Brauns under that name in
