0. ceplniloles, Sin., as sliowii by the measurements of the 

 head and the shape of the mandibular teetli, comes in the 

 coi'iariiis group. I3elo\v is a description of the type (Oxford) 

 from Ceram : — 



^. Length (without mandibles) 11*3 mm.; length of* 

 mandibles 1*7 mm. 



Head as al)ove. Mandibles broad, distinctly but irregu- 

 larly denticulate along inner border (Smith says ''no teetii"), 

 apex with three teeth {vide fig. 6). Clypeus prolonged in a 

 blunt point between the frontal earinse. Antennal scapes 

 barely extend beyond occipital border. Occipital groove 

 extends to end of antennal fossae, dec[)est anteriorly. 

 Thorax slightly emarginate l)et\\cen meso- and e})inotuni. 

 Node bioad at base, narrowing gradually to the spine, which 

 is rather short and thick. 



Mandibles with one or two indistinct punctures near the 

 apical toothy very faintly and irregularly striate along their 

 outer half. Whole of upper surface and sides of head finely 

 and regularly striate, the stri<e coarser in front and spread- 

 ing fan-wise from the frontal carinse to the base of eyes, 

 and diverging slightly on the vertex. 



Pronotum finely striate transversely, anteriorly some of 

 the striae form concentric ovals (this cannot be seen from 

 above, but only from the sides) ; mesonotum Avith feeble 

 stria?, arched anteriorly ; epinotum regularly and trans- 

 versely striate. 



Node encircled with fine striie. 



Entire gaster finely and longitudinally striate, and finely 

 reticulate at the base of each segment. On the first segment 

 the lateral striae encircle the basal half of the segment, so 

 that this half, viewed from in front, appears to be trans- 

 versely striate. 



A few outstanding hairs on pronotum and gaster, par- 

 ticularly on the apical segments. Pubescence very scanty. 



Dark ferruginous, almost fuscous ; maudibles, antcnnie, 

 and legs paler, gaster darkest. 



One of the co-types from Ceram is paler.
