 penultimate three times broader than long, the 1 lth conical. Thorax 

 .shorter and a little narrower than the head, transverse, widest at 

 the anterior angles, the sides converging in a straight line to the 

 rounded posterior angles ; the disc rather broadly impressed in the 

 middle throughout its length; puncturation very fine and rather 

 close ; finely pubescent. Elytra scarcely longer but a little broader 

 than the thorax, square, pitchy, obscurely lighter on the disc; 

 puncturation very tine and rather close ; finely pubescent. Abdomen

One specimen, taken from beneath bark. 



39. Actobius laticeps, n. sp.

 posterior angles ; moderately finely and rather sparingly punctured, 

 a broad area from the front to the base in the middle quite im- 

 punctate ; punctures setiferous ; the eyes larger and more prominent 

 than in A. signaticornis; no ground-sculpture visible. Antennae 

 slender, the 2nd joint dilated, shorter than the 3rd, the others dis- 

 tinctly longer than broad, gradually decreasing in length. Thorax 

 a little narrower than the head with the eyes, widest at the broadly 

 rounded anterior angles, narrowed posteriorly in a straight line, 

 slightly longer than broad ; disc with a somewhat irregular row of 

 seven or eight moderately-sized setiferous punctures on either side, 

 externally finely, sparingly and irregularly punctured. Scutellum 

 triangular, sparingly punctured. Elytra a little longer than the 

 thorax, slightly longer than broad, finely, asperately and some- 

 what sparsely punctured, more finely and not so closely punctured 

 as in A. signaticornis. Abdomen closely and finely punctured and 

 pubescent throughout, the posterior margins of the segments 

 narrowly and obscurely reddish; the puncturation not so dense 

 and fine as in A. signaticornis.
