Stephamts onartini Stadelmann (1), p. 236, $ cT . 



2 . Frons transrugose, coarsely punctate below ; occiput 

 coarsely transrugose ; posterior margin of head sharply bordered. 

 Basal flagellar joints normal. Neck coarsely and obliquely 

 rugose ; semiannular coarsely punctate with polished posterior 

 margin. Mesonotum diffasel}'- punctate. Scutellum smooth, 

 with a few diffuse marginal punctures. Mesopleurae shining, 

 apically punctate ; metapleiTrfe densely punctate, separated by a 

 deep and shining sulcus from the coarsely cribrate-punctate 

 median segment. Petiole basally longitudinally, apically trans- 

 versely rugose, and as long as the i-emaining segments together ; 

 apical segments dull, Terebra very little longer than body, 

 sheaths entirely black. Hind cox?e transi-ugose ; hind femora 

 finely trans-striate and tridentate ; tarsi three-jointed. 



Black ; head, scape, and first flagellar joint red ; anterior legs 

 nigro-f ascous ; all tarsi testaceous. Wings subhya,line. 



(S . Similar to $ . Nigro-f ulvous, head red, antenna3 basally 

 red, apically nigro-ferrviginous ; base of hind femora ferru- 

 ginous ; tarsi five-jointed. Length, 5 , 17-20 mm.; c?, 15 mm; 



Habitat : Dele, Sumatra. Named after the captor, Hofrat 

 Dr. med. L. Martin. Type in Berlin Museum. 



Stadelmann states that this species closely resembles S. sulci- 

 frons Schlett., which has the neuration of the subgenus Stephamts; 

 he states also that the neuration is complete, but his figure 

 {I. c. pi. 6. fig. 4) shows the external submedian cell open behind 

 as in Parastephanellus. 



Other difi"erences are said to be : the sulcus on vertex indistinct 

 in 5 1 wanting in S ; third flagellar joint longer, petiole longer 

 and more conrsely sculptured ; hind femora trans-striate and 

 tridentate, but smooth and bidentate in sidcifrons. 



Easily known by the tridentate hind femora and large size. 



2. ORBiTALis Brues. 



Parastephanellus orhitalis C L. Brues, p. 98, S • 



f? . Frons and vertex centrally transrugose ; cheeks longer 

 than scape ; posterior margin of head bordered but not reflexed. 

 Basal flagellar joints normal. Pronotum transrugose, the 

 rugosities extending obliquely to the pleurae ; a punctate area on 

 each side before the smooth posterior margin. Mesonotum
