150 Mr. G. Lewis on new 



Sternoccelis fulvuSj n. sp. 



Breviter ovatus, rufo-ferrugineus, sat dense fulvo-setulosus ; fronte 

 obscure puuctulata, stria utrinqtie elevata, antice late interrupta : 

 pronoto lateraliter bisinuato, angulis posticis obtusis ; elytris 

 tenue et obscure tristriatii ; tibiis modice dilatatis. 



L. li, c. If mill. 



The above is similar to setulosus, Mspanus, and Walkerij 

 but it is smaller, the thorax is less transverse, and the dila- 

 tation of the tibiae less, and the prosternal stride are a little more 

 parallel to each other and better defined. The sternal pit 

 is also slightly deeper than in setulosus or Walkeri. 



I obtained a great number of this species in Algeria, at 

 Ham man Rirha (altitude 2300 feet), this spring. 



Sternoccdis arachnoides, Fairm. 



This insect has long narrow legs, but in its general struc- 

 ture it is similar to those of the Mspanus-gxoxv^. The pro- 

 sternum has well-defined stria3, which are sinuate at the coxai 

 and then pass forward, widening out slightly from each other. 

 The meso- and metasternal basin is more circular than in the 

 other species known at present. 



SternocoBlis 'puherulus, Motsch. 



The prosternum of this species is of very curious struc- 

 ture. It is very prominent, punctured, and without strige, 

 and the anterior lobe is very short and transverse, I am 

 much indebted to Signor Enrico Ragusa for a specimen of 

 tliis species. Hetcerius ferrugineus is the only species of the 

 Myrmecophilous Histeridai known from Italy; it is asso- 

 ciated with Formica fusca. When the nests of Aphanogaster 

 are investigated, one or more new species will possibly be 

 found in Sicily or on the adjacent mainland. 



Sternocoelts Lewtsi, Reitter. 



In this species the space between the prosternal striae is 

 narrow and the stria3 are very parallel to each other, widening 

 out only on approaching the base. S. Merkh'i, Schmidt, is 

 compared by the author to Lewisi ] but the prosternum is 

 concave and apparently without strige.
