12. LEUCODONTUS Schlett. 



Stephanus leucodontics Schlett., p. 121, 5 . Diaste2)7ianus I. 

 Enderl. (2), p. 475. 



2 . Frons finely, transversely coriaceo - rugose ; anterior 

 frontal tiibei'cle wanting (otherwise always present) ; occiput 

 very short, finely trans-striate, more coarsely behind the ocelli. 

 Posterior margin of head simple; cheeks longer than scape. 

 Second fla,gellar joint one and a half times as long as first ; third 

 longer than first and second together. ISTeck elongate and 

 slender, obsoletely trans-striate ; semiannular subnitidulous, 

 with a central longitudinal trans-striate fovea. Mesonotum 

 finely and irregularly ti-ansrugoso-punctate. Scutellum entirely 

 smooth. Mesopleur* smooth and shining, with a few superficial 

 punctures below ; metapleursB smooth and shining in front, 

 rather coarsely reticulate-rugose behind. Median segment 

 centrally a,nd basally smooth, laterally with large punctures, 

 which are more dense apically. Petiole very finely transrugose, 

 as Ions' as rest of abdomen, which is smooth and sti'ongly 

 nitidulous. The terebra broken ofi". Hind coxa3 slender, trans- 

 striate ; hind femora entirely smooth, bidentate ; hind tibia3 

 compi'essed to beyond middle. 



Black; frons rufo-testaceous, rest of head ferruginous; antennas 

 basally testaceous ; pronotum and legs brown ; teeth of hind 

 femora white, and hind tarsi white-marked. Wings entirely 

 hyaline. 



Length 10 mm. 



Habitat : Sarawak. Type in Royal Nat. Hist. Museum, 

 Berlin. 



The absence of the usually well-developed frontal anterior 

 tubercle will distinguish this species from all others. It closely 

 resembles Z>. p«/Zesce«s Schlett. and F. indicus Westw. It may 

 be distinguished from both by the short occiput, simple posterior 

 margin of head, and by the sculpture of the hind femoi-a ; from 

 F. indicus Westw. it further difiers in the neuration. 



A specimen in the British Museum, from Singapore, has 

 a white-banded terebra; length of body 10| mm.; terebra 

 9 mm.

2 . Frons finely arcuate striate ; vertex trans-striate ; occiput 

 nearly smooth. Space between the posterior ocelli trans-striate. 

 Posterior margin of head bordered. BasaJ flagellar joints normal. 

 Pronotum very finely trans-striate and rather shining, basal 

 margin smooth ; mesonotum almost smooth. Central lobe of 

 scutellum finely punctate. Propleuras finely striate ; mesopleura; 

 smooth and shining ; metapleuras and median segment cribrate 

 punctate, separated by a carina. Petiole extremely finely trans- 

 striate, shorter than rest of abdomen, which is smooth and
