 The type of this species was taken from an ants' nest ])y Cnm-

RyhariK (ctafiHii iiiae, n.sp. 



Brij^-ht castaneous, legs (knees excepted) and palpi somewhat paler. 

 With short, pale pubescence, interspersed, especially on al)domen, 

 with some longer hairs. 



Head highly polished ; with a (for the genus) rather small and 

 j)artly open fovea close to each eye, frontal impression shallow. 

 Antennae rather long, first joint apparently (when seen from above) 

 no longer than second, but really (when seen from the side) distinctly 

 longer, third to sixth rather small, seventh larger, eighth slightly 

 smaller than seventh but larger than sixth, ninth and tenth small, 

 eleventh snbovate, apex pointed, about as long as three preceding 

 joints combined. Prothora r moderately transverse, widest at about 

 apical third ; with a small medio-))asal fovea, indistinctly connected 

 along base with a comparatively suuill fovea on each side. Elytra 

 about as long as wide ; each with sutural stria distinct, dorsal dis- 

 tinct at base, but not traceable beyond middle ; epipleural furrow 

 absent, but marginal stria distinct ; punctures small but fairly dis- 

 tinct. Metaxtiinuni rather shallowly impressed. Abdomen somewhat

 Orford, from a nest of Eetatnmnia iiiet(dHrinn (A. M. Lea). 



In size and general appearance close to E. ■')-f(>veata, but antennae 

 and prothoracic impressions different. The inflation of the seventh 

 and eighth joints is not very strong, 1 ut is such that they are notice- 

 ably larger than the preceding or following ones. Tbe two specimens 

 l^etore me appear to ))e males, although they have no distinctive 

 sexual features on the under surface and legs.
