110 THE KNTOMOLOGIST. 



notum small and trilobed, punctate in front ; mesopleurae smooth 

 and pubescent ; metanotum deplanate, not punctate, obsoletely trans- 

 striate centrally before apex ; metapleurae confluent therewith. 

 Scutellum not longer than broad, apically obtuse, apically margined 

 on either side, with its basal sulcus crenulate. Abdomen hardly 

 smoother apically, dull ; petiole shorter than rest of segments ; 

 second segment basally constricted, the sixth apically emarginate ; 

 abdomen 6 mm. ; petiole 2^ mm. ; terebra 8 mm. Hind legs stout ; 

 coxffi as femora, which are strongly incrassate and beneath both 

 bidentate and basally angulated ; tibiie rather longer, compressed 

 only to centre and there incised ; tarsi thi'ee-jointed. Wings lacteous- 

 hyaline, basal nervures and centre of stigma infuscate ; a conspicuous 

 circular infumate spot in the external submedian cell and another, 

 very faint below the radius. — Rufotestaceous ; the eyes, ocelli, 

 mandibular apices, frenum conspicuously, extreme base of petiole, the 

 thyridii of second segment and a circular spot on either side of the 

 fourth quite black ; femoral teeth white ; terebral sheaths rufescent, 

 with their apices and those of the flagellum nigrescent. 

 Length, 10 mm. 



The type, in the British Museum, was captured by H. Swale 

 on May i2th, 1914, at Lonely Mine, in Rhodesia.

(^ $ . This species is extremely similar to D. ahttaceus in all but 

 one or two essential details of structure. Superficially it may be 

 distinguished by having the whole apex of the metathorax discally 

 black ; the apices of segments 2 to 4 and base of the second 

 infuscate, with apex of the hind coxge, base, and a transverse band 

 before apex of their femora, nigrescent. The apex of petiole flaves- 

 cent ; and both abdomen and wings with no dark spots. — The 

 sculpture is distinct in the transcarinate vertex, shorter and trans- 

 versely striate prothorax, superficially punctate metanotum, more 

 slender hind tibiae, which are constricted to well beyond their centre ; 

 a third (basal) tooth below the hind femora ; hind cox® apically 

 transaciculate. Stigma lanceolate and not centrally infuscate ; but 

 the main difference is, perhaps, the prolongation of the median 

 nervure between the discoidal and external submedian cells. 



The measurements are alike in both, and the present (^ hardly 

 smaller ; length 10 mm. 



In the British Maseum is an old pair from Fred. Smith's 

 collection, labelled " Port Natal," and a female, bearing a green 

 ticket, also so localised ; probably all were there captured by the 

 Swedish collector Gueinzius about 1859. The elongate median 

 nervure places this species in Fcenatopus ; it is not a Neo- 

 stephanus;, as placed by Enderlein, ' Zool. Anzeig,' xxviii, 1905, 

 p. 474.
