Wasps of the Genus Tachytes. 29" 



? . Eyes separated on the vertex by a distance equal to 

 the length of the third joint of the flagellum. Clypeus 

 broadly subtruncate at the apex ; vertex with sparse distinct 

 punctures; second joint of the flagellum distinctly longer 

 than the third. Pygidial area subtriangular, rather broadly 

 rounded at the apex, clothed with dark reddish pubescence^ 

 which changes to fuscous in some lights. Second sternite 

 shining deeply aud sparsely punctured, with a smooth tri- 

 angular area in the middle of the apical margin. Third 

 abscissa of the radius longer than the second by about one- 

 quarter, equal to the distance between the recurrent nervures 

 on tlie cubitus. Basal joint of fore tarsus with six spines. 



cJ . Eyes separated on the vertex by a distance equal to 

 the length of tlie first joint of the flagellum ; antennae 

 rather stout, the third to sixtli joints of the flagellum feebly 

 arcuate beneath. Scutellum rather more distinctly punc- 

 tured than the mesonotum ; seventh tergite subtriangular, 

 rather narrowly truncate at the apex, clothed with red gold 

 pubescence. Eighth sternite truncate at the apex, the angles 

 not produced. 



Hab. Meru lowlands, Ngare na Nyuki (Sjostedt), Novem- 

 ber, $ ; Nyasaland, Mlanje [S. A. Neuve), February, ? ; 

 S.E. shoi'e of Lake Nyasa between Ft. Maguire and Ft. 

 Johnston {S. A. Neave), March, ^J • 



My description is taken from a pair from Nyasaland, 

 whicli I think belong to Cameron's species, but I have not 

 examined the type. 



33. Tachytes associata, sp. n. 



c? . Niger ; tegulis, femoribus apice, tibiis tarsisque ferrugineis ; 

 fronte clypeoque aureo-pilosis ; thorace segmentoque mediano 

 dense et pallide fulvo-pilosis, mesonoto lateribus aureo-pubes- 

 cente, segmentis dorsalibus 1-5 apice fascia argeiiteo-pubescente ; 

 area pygidiali pallide aureo-pubescente ; alis pallidissime fulvo- 

 hyalinis, nervis testaceis. 

 Long. 15 mm. 



S . Near testaceinerva, Cam., but the clypeus is very 

 narrowly depressed on the apical margin, the depressed 

 portion slightly porrect and with a distinct angle in the 

 middle ; vertex not distinctly punctured ; eyes separated on 

 the vertex by a distance equal to the length of the second 

 joint of the flagellum ; basal joint of fore tarsi with five 

 spines; second ventral segment finely and evenly punctured, 

 subopaque, not shining with sparse large punctures on the 

 apical half as in testaceinerva : seventh tergite broad, truncate
