Species o/' Histeridge. 209 



Kecord/ 1883, as a Histerid, does not belong to the Coleo- 

 ptera. 



Ebonius, n. gen. 



Corpus subcylindricum, haud depressum. Caput retractile. An- 

 tennae sub frontis margine insertae, clava ovali 4-articulata, foveola 

 profunda sub angulo prothoracis. Pronotum antice angustatum. 

 Prosternum latum, marginatum. Tibiae extus dentatse. Propy- 

 gidium transversum ; pygidium supra convexum apice reflexum. 



This genus may be placed next to Omalodes^ from which 

 it can be at once separated by the broad prosternura, the more 

 parallel form, and the singular pygidium, which is double, as 

 in Horn's genus Teretriosoma. 



Ehonius poUtuSj n. sp. 



Oblongus, subcylindricus, supra depressus, niger, nitidua ; fronte 

 grosse punctata, margine piano antice interrupto ; pronoto stria 

 integra, punctato, ante scutellum foveolato ; elytris striis tenue 

 impressis, 1-3 suturalique integris, 4 et 5 punctiformibus, medio 

 abbreviatis ; propygidio utrinque punctato ; pygidio medio sub- 

 tuberculato et grosse punctato. L. 8|-9 mill. 



Hah. Para. 



There are two examples of this curious insect in the British 

 Museum, and I purpose shortly to give figures of both the 

 upper and under surfaces. The fore tibige have five or six 

 teeth ; the middle and hind pairs three each. 



Hister indicusj n. sp. 



Suborbicularis, convexus, niger, nitidus ; fronte subtilissime et 

 parce punctulata, stria circulari ; pronoto parce punctulato, stria 

 interna integra, valida, externa nulla; elytris striis crenatis, 

 subhumerali valida impressa, 1-4 integris, 5, basali rudimento 

 aucta, suturalique in medio, abbreviatis ; propygidio pygidioque 

 dense et grosse punctatis ; prosterno basi lato et marginato ; 

 tibiis multispinosis. L. 4| mill. 



Hob. Assam. 



H. indicus is close to concordans^ a species found in the 

 Deccan. The differences lie in the absence of the short internal 

 thoracic stria,the deep and complete subhumeral stria, the large 

 and deep punctuation of the pygidium, the widening out of the 

 base of the prosternum, and the lesser dilatation of the fore 

 tibiae, which are armed with seven or eight spines in the place 

 of four teeth as in concordans. 



Hister calidus^ Er. I give the diagnosis of this species; it
