A single specimen of tin's species was given to me hj my lamented 

 friend Gr. R. Crotcli, who captured it at Eeynosa ; and I subsequently 

 myself found a single individual in the same locality. 



BrxniNus Manueli, n. sjo. 



Siifescens, postlce plus miiiusve nigricans; frotliorace antice im- 

 fundato ; elytris ohsolete punctatis. Long. corp. I-3 mm. 



3fas : antennarum articulo primo incrassato, intus apice tuberculo 

 minimo ; 2" magno, primo latiore, latitudine vix hreviore, onargine inferno 

 convexo quam externa paulo longiore ; tibiis anterioribus intus ante 

 apicem minus fortiter angustatis, pedibus posteriorihus gracilibiis. 



B. nodicorni peraffinis ; maris antennarum articido 2" longiore, mar- 

 gine interno elongato hand acuminato, facile distinguendus. 



Pafria, Sabaudia. 



Tliis Bythinus was captured during the month of May last at 

 Albertville, Savoy, by Count de Manuel and myself, and I have great 

 pleasure in naming it in honour of my hospitable and genial friend. 



Batrisus sibiricus, n. sp. 



Magnitudo et statura B . formicarii. Biifns, elytris exceptis, sub- 

 opacus ; anfennce crassiiisculcB apice leviter clavatce ; capite punctato, 

 vert ice sat elevafo, subtilissime carinato ; elgtris par ce, fortiter sed parum 

 profunde punctatis ; ahdomine pubescentia depressa subtili sat dense 

 vestito. Long. corp. 3 mm. 



Mas: antennarum articulo ultimo intus medio tuberculo obsoleto ; 

 femoribus intennediis arcuatis ; tibiis omnibus basi compressis, inter- 

 mediis apice unco brevi sat valido armatis. 



Fern, incog. 



Antennee long and stout, joints 2 — 8 bead-liko. Head much elevated over the 

 insertion of the antcnnso, the vertex rather strongly elevated, and with an extremely 

 fine line along its middle, eyes in front moderately large, but truncate behind, and 

 with the head projecting behind them as a fine acuminate tubercle ; when viewed 

 from the front the appearance is exactly as if the eyes themselves were spined or 

 angulated. Thorax similar to that of B.formicarius, but with the middle fovea 

 indistinct, and the front parts more distinctly punctured. Elytra redder and more 

 shining than the rest of the surface, sparingly but distinctly (though not deeply) 

 punctured. First dorsal segment of the hind body very finely margined at the sides, 

 without impressions at its base, but with two very short indistinct raised lines in the 

 middle behind the elytra, and outside these with a longer, very fine, oblique line on 

 each side. 



I have seen but a single S2)ecimen of this fine species ; it comes 

 from Eastern Siberia. Though clearly allied to B. formicarius, it is 

 verj' distinct therefrom. In conncctioa with this insect it may bo
