MalthocJes, recently established by Kiesenwetter to contain a portion of Mal- 

 thimis of Latreille, differs principally from the latter in having the head more 

 convex and less suddenly constricted behind, in the antennae being inserted slightly 

 nearer to the inner margin of the eyes, and in the mandibles being simple inter- 

 nally, instead of (as in that genus) armed with a powerful tooth. It possesses 

 however many characters in common with MaWi'mus, — as, for instance, its linear- 

 elongate form, its delicate and flexible texture, its apically abbreviated elytra and 

 its exposed wings, — which apart from the peculiarities of its oral organs (amongst 

 which, their ahnost membranous general structure, and the subfusiform, ex- 

 tremely acviminated terminal joint of the palpi should be especially noticed), will 

 serve at once to distinguish it from every other allied grouj). They are insects 

 nearly, if not quite, peculiar to temperate latitudes, upwards of forty species 

 having been described as European ; but, owing to the extraordinary softness of 

 their outer envelope, which is liable to shrivel, or collapse, when dry, they are 

 not always easy of determination. They occur for the most part amongst dense 

 vegetation and flowers, and are often remarkably gregarious.

M. angusto-linearis subnitidus infuscato-niger et cinereo-pubescens, prothorace brevi, elytris valde 

 abbreviatis vix pallidioribus necnon ad apicem obsolete flavo-terminatis, antennarum basi pedi-

M. narrow and linear, very sligbtly shining, most delicately and remotely punctulated, obscure 

 brownish -black, and densely clothed with a rather robust cinereous pubescence. Head convex. 

 Prothorax very short. Elytra usually a little paler than the head and prothorax, and exceedingly 

 abbreviated ; rather wrinkled, and with the apex of each terminated with a very obscure (some-
