very larjije. Ei/es prominent. Thorax oviform, rather 

 longer than broad; there is a distinct ante-basal linear 

 impression, a fovea at each side, and a smaller median fovea, 

 but there is no well-developed discoidal groove, the surface 

 is smooth. Elytra rather longer than broad, moderately 

 rounded laterally; on each there is a fine sutural stria and 

 short intra-humeral impression, the shoulders appear as if 

 longitudinally elevated. Legs moderately long, the front 

 and hind tibiae straight, their tarsi elongate. Hi/id body 

 with four exposed segments, the basal three strongly mar- 

 gined and of nearly equal length, the first slightly flattened 

 medially.

1 have much pleasure in naming this inconspicuous but 

 interesting little beetle in honour of Mr, J. H. Lewis, who 

 sent me a mounted specimen which he found in an ant's 

 nest. The female apparently has not been seen, 



Euplectus caviceps, sp, n. 



Elongate, shining, fulvescent, impunctate, clothed with 

 decumbent greyish pubescence; antennae, palpi, and legs 

 yellow. 



Head nearly as broad as the thorax, narrowed anteriorly, 

 its whole central portion deeply hollowed, and with a fine 

 dark longitudinal stria within the cavity, the frontal margin 

 is on nearly the same plane as the flattened tubercles. 

 Eyes quite lateral, rather small, convex, coarsely facetted. 

 Antennce moderately short and stout, basal joint stout, 2nd 

 oviform, nearly as large as the 1st, joints 3-6 small and 

 moniliform, 6th slightly smaller than 5th, 7th and 8th 

 transverse and distinctly broader than the preceding one, 

 9th and 10th transverse, about twice the size of the 8th, 

 11th large, conical, acuminate, and pubescent. Thorax quite 

 oviform, with a transverse impression near the base, termi- 

 nating in a fovea at each side ; between the former and the 

 basal margin there is a small median fovea, and there is 

 also an elongate discoidal impression. Elytra subquadrate, 

 their sides moderately rounded, shoulders narrowed; the 

 sutural strife are well marked, and there is an elongate intra- 

 humeral impression on each. Hind body oblong, basal three 

 segments strongly margined and about equal, fourth nearly 

 as long as third, the terminal depressed. Legs elongate and 

 slender, Tarst slender, apparently with one claw only.
