new Species of Histeridae. 267 



extus sparse punctato : pygidio dense ocellato-punctato ; prosterno 

 lato ; tibiis anticis 4-dentatis. 

 L. 10 mill, (absque mandibulis). 



Oblong-oval, depressed, black and shining ; the head 

 smooth, impressed between the mandibles ; mentum in male 

 concave and smooth, not carinate : the thorax, lateral stria 

 complete and similar to that of 11. Baulnyi, Mars. ; there is 

 a band of fine, not conspicuous, punctures scattered along the 

 sides ; the anterior angle has a small emargination and close 

 to the emargination there is a deep oval, somewhat oblique, 

 fossette : the elytra, lateral furrow widest in the middle and 

 abbreviated a little before and behind ; striae, first dorsal is 

 one fourth of the elytral length and has a short bent appendage, 

 second shorter, not quite half the length of the first : the pro- 

 pygidium is sparsely punctured on the outer edges, but not 

 at the base ; the pygidium is densely and ocellately punctate, 

 with the posterior border narrowly smooth ; the prosternal 

 keel is broad and scarcely narrowed at or before the coxae. 



This insect is very similar to H. Baulnyi, Mars., but it 

 differs from it in the thoracic auriculifonn fovea being deeper, 

 more circular in outline, and in its position being nearer the 

 angular emargination, the apical elytral stria is bent, not 

 straight, and the pygidium is distinctly ocellately punctured. 



Hub. Borneo. 



Hololepta syntexis, sp. n. 



Oblongo-ovata, subdepressa, nigra, nitida; fronte inconspicue bi- 

 striata ; pronoto impunetato, stria laterali in angulo antico desi- 

 nente ; elytris striis 1-2 brevibus, 3 vix conspicua ; propygidio 

 apice bifoveolato, punctis sparsis late cincto. 



L. 8 mill, (absque mandibulis). 



Oblong-oval, depressed, black and shining ; the forehead 

 smooth, with two very short, almost obsolete, transverse 

 striae, <$ mentum with a short but distinct carina ; the 

 thorax is impunctate, marginal stria very fine, lateral stria 

 well marked, especially at the anterior angles, both striae 

 terminate behind the angle, male has no thoracic emargination 

 or fovea ; the elytra, lateral fossette reaches the base, but it is 

 shortened before the apex, 1 dorsal stria is about a fourth of 

 the elytral length, 2 half the length of the first, 3 is just 

 visible as a rudiment, there is no appendage ; the propygidium 

 is bifoveolate at the apex, with a border of scattered punctures, 

 except between the foveae, where the surface is smooth j the 

 pygidium is rather closely punctured, the punctures varying 

 somewhat in size and leaving the posterior edge narrowly
