 The anomalous little insects for which the present genus is 

 established are quite unrepresented (unless indeed I am very 

 much mistaken) in De Marseul's elaborate Monograph. In the 

 construction of their sterna, broad, membraneous outer max- 

 illary-lobe and their maxillary-palpi, as well as in their large and 

 apically bi-emarginated mentum, they have indeed a good deal in 

 common with Epierus ; but in their excessively minute size, 

 coarsely and regularly punctured, and (beneath a high magnifying 

 power) even s])an\)g]y-pubescent surfaces, unstriated elytra, and 

 the wide and deep line with which either side of their pronotum 

 is impressed at a considerable distance within the edge, would, 

 apart from other differences, at once separate them from the 

 members of that group. Nevertheless their peculiarly structural 

 features are still more remarkable, — amongst which the abbre- 

 viated second joint of their labial palpi, which is not longer (al- 

 though broader) than the first, their narrowly uncinated inner 

 maxillary-lobe (as in Eutriptus), and their rather long and slender 

 legs, accompanied with the sudden and singular dilatation of the 

 anterior-tibiae (which are expanded on their outer edge, from the 

 middle to the apex, into an elongate-squarish plate), should be 

 especially noticed. In the formation of their tarsi, also, the first 

 four joints of which are subequal (the basal one he'mg, if anything, 

 a trifle larger than the others), no less than in the elongate second 

 joint of their funiculus (which is but slightly shorter than the 

 preceding one), the exponents of Euhrachium still further recede 

 from the Epieri,
