num of the Cossonides. Lymantes has the eyes placed on the rostrum, 

 and as far as our fauna is concerned, is the point of greatest difference, 

 but Catolethrus of the next group has a similar structure. 



Lymantes Schonh. 



Head globular, rostrum separated from it by a deep constriction, 

 moderate, robust, subquadrangular, rounded at the angles, arcuate ; 

 scrobes commencing a short distance from the tip, oblique, visible only 

 in front. Antennae anterior, moderately robust, scape gradually clavate, 

 nearly attaining the eyes ; funicle seven-jointed ; 1-2 elongate, obcouis, 

 the former longer, 3-7 transverse, closely placed, increasing gradually in 

 width ; mass moderately large, subglobular, compact. Eyes situated on 

 the rostrum, lateral, small, depressed, narrow, obliquely transverse. 

 Thorax oblong quadrate, depressed, suddenly and for a short distance 

 narrowed in front, truncate at apex and base. Scutellum invisible. 

 Elytra moderately convex, gradually declivous behind, narrower at pos- 

 terior third, not larger at base than thorax and feebly emarginate. 

 Legs moderate, anterior coxae feebly separated, thighs gradually in mass, 

 the anterior more strongly than the others ; tibiae narrow, a little com- 

 pressed, slightly arcuate at the extremity, which is mucronate. Tarsi 

 short filiform, fourth joint long, claws slender parallel. Mesostemum 

 narrow, linear. Form oblong, elongate, unequal. 



The above description of the genus is copied from Lacordaire as the 

 species is unknown to me in nature. 



L. scrobieollis Gyll. Schonh. Gen. Cure. IV., p. 1086. 



"Elongatus, angustus, subdepressus, nigropiceus, nitidus, parce cinereo- 

 setulosus, antennis pedibusque dilutius ferrugineis ; rostro porrecto, 

 seriatim rude punctato ; thorace oblongo, disperse varioloso-punctato ; 

 elytris remote punctato-striatis, interstitiis angustis, puuetulis valde 

 remotis adspersis, setulis parvis ciiiereis, praesertim versus apicem ad_- 

 spersa. Corpus subtus profunde disperse punctatum, nigro piceum." 



Of the size and facies of Dryophtliorus. 



For a time I supposed the insect, which has been described on a pre- 

 vious page as Dryotribus mimeticus, to be Lymantes, of which it has 

 many of the characters ; but their identity cannot be for a moment 

 suspected without admitting inaccuracies on the part of Schonherr and 

 Lacordaire which are almost inconceivable, although the latter author 

 states in the table (Genera, VII., p. 328) of genera that Lymantes is eye- 

 less, and on a subsequent page (p. 332) the eyes and their position are 

 carefully described. 



Cossonides. 



Funicle of the antennae seven jointed. Eyes normally placed. Meta- 

 steruum at least moderately long. 



The above is all that can be said in general of the genera which com- 

 pose this group. Many of the genera are extremely closely allied, and 

 as but few are known to me in nature, I have been compelled to rely 

 entirely on the books.
