720 MR. E. A. ELLIOTT ON THE 



the metapleurse by a fine longitudinal carina, behind which is a 

 narrow sulcus. Petiole basally transrugose, then finely trans- 

 striate, apically smooth, shorter than rest of abdomen. Terebra 

 nearly as long as body, ferruginous, sheaths entirely black. 

 Hind legs with coxas stout, with setiferous punctures in front, 

 more sparse towards middle, apically finely trans-striate ; femora 

 inflated, microscopically finely and densely alutaceous and 

 punctate. 



Head, thorax laterally, legs including tibiie and petiole beneath 

 with long, sparse, coarse hairs ; similar but shorter and finer 

 hairs on abdomen. 



Wings hyaline, apically infumate, stigma opaque, nervures 

 pitch-brown. 



Black ; mandibles and antennae red-brown ; cheeks and base 

 of anterior femora red-yellow. Wings faintly iridescent. 



Length 25 mm. Terebra 23 mm. (Gribodo : 26 mm. ; terebra 

 20 mm.) 



Habitat : Mahal Uonz, Shoa, East Africa, 1 § taken by 

 Marquis Orazio Antinori. Described from the unique type in 

 the Museum at Genoa by W. A. Schulz. 



The extremely short antennae and six frontal tubercles, as 

 described by Ginbodo, inclined Schletterer to doubt this species 

 being a true Stephanus, but the latter character proves to be a 

 mistake, the five fi^ontal tubercles being quite normal ; and 

 Schulz states that the right antenna is complete, the apical 

 joint is normally pointed and \^ times as long as the penultimate, 

 not showing any signs of being abnormally formed or dwarfed. 



This species resembles S. gigas and S. tihiator Schlett. in the 

 verjr coarse sculpture of the body and especially of the temples, 

 but differs from both in the unusually short antennse. From 

 S. gigas it may be further distinguished by the bordered posterior 

 margin of the head and by the broadly smooth posterior margin 

 of prothorax ; fi'om S. tihiator it differs in the absence of the 

 longitudinal sulcus on occiput, in the formation and sculpture of 

 the prothorax, etc. No other specimen having been yet taken, 

 it must remain uncertain whether the short antennse are truly 

 characteristic of the species. 



3. GIGAS Schlett. 



Stephanus gigas Schlett., p. 96. 



Frons vei-y coarsely and irregularly rugose ; occiput arcuately 

 rugose near the posterior ocelli, behind this centrally trans- 

 versely, laterally irregularly rugose. Temples covered with 

 dense, rather deep and partly confluent punctures, excepting a 

 smooth space behind ocelli. Posterior margin of head simple. 

 Second flagellar joint fully twice as long as first, third only as 

 long as second. Neck coarsely transrugose, semiannular coarsely 

 rugose-punctate throughout, excepting an indistinctly rugose 

 impression near tegul^. Mesonotum centrally somewhat smooth
