SIMA. 115 



Hah. Travancore {Ferguson) ; and one specimen which I identify 

 with this .species, from the Pegu Yoma in Lower Burma.

" 5 . The head with the sides parallel almost up to the anterior 

 margin of the eyes, and above that strongly convex to the occipital 

 lateral angles. Eyes very large, as long as the space which sepa- 

 rates them from the anterior margin of the head, posterior margin 

 of the eyes reaching up to the posterior fifth of the head. The 

 scape short and thick, extending up only to the anterior third of 

 the eye. The head is somewhat longer than in ^S'. allahorans (less 

 long than in typical >S. difficilis). Thorax as described * by 

 Emery for S. difficilis, but the metanotum is distinctly sub- 

 margined, nearly margined. The basal face of the metanotum is 

 a little convex, subhorizontal and very distinct from the sloping 

 face, which is subvertioal, not forming a single curve with it as in 

 S. si(jgi. Eirst node as in the type of the species, but with a 

 small tooth directed backwards towards the posterior luider apex 

 of the node ; second node a little less than twice as broad as the 

 1st, and about as long as broad. Legs and antennae of a mixed 

 brown and yellow. The abdomen with a somewhat dense pruinose 

 pubescence. Eor the rest corresponding with Emery's description 

 of *S. difficilis. The pro-meson otum is very feebly convex, as in 

 >S'. allahorans. Yery distinct from S. aitheni and 8. sigr/i f by the 

 form of the thorax and of the pedicel." (Forel.) 



Length, ^ 4-5*5 mm.

I have failed to identify this species.

" ^ . Anterior portion of the clypeus subvertical, concave and 

 margined ; posterior portion extremely short, reduced nearly to a 

 transverse carina, situated in front of the frontal carinse and ciliated, 

 without teeth and not crenulate nor projecting in the middle. 

 Mandibles shining, nearly smooth, with only a few feeble striae. 

 Head rectangular, only a little longer than broad. Eyes very 

 large, their anterior margin reaching to a little below the middle 

 of the sides of the head and posteriorly to between the posterior 

 5th and 6th of the same (the eye occupies a good third of the 

 length of the head). Frontal carinae parallel, very close together. 

 Pronotum margined, nearly square. Pro-mesonotum forming a 

 marked convexity, more n)arked than in S. nigra. Emargination 



* " The structure of the thorax is as in that species (i. e. Si}7ia allahorans, 

 Walker), but the epinotuni ( = iiietanotuiii) is less compressed, its dorsal face a 

 little depressed." — Emery's description of S. difficilis from Sumatra (Ann. Mus. 

 Civ. Gen. xl (1900), p. 677).
