 tending onto the mesosteruum. l^^yes large, pointed interiorly. Ocular 

 [^'•^'- »'!'•] lobes more or less prominent. 



Thighs sometimes toothed beneath. 

 Tibi.c spined at the end. lu Cryp- 

 torhj'uchus proper the tibioe have 

 a band of rigid hairs near the ex- 

 tremity, usually bright yellow, but 

 sometimes black. These are small 

 species found on plants. The bodj'

name sigiiilies having a concealed snout^ and has reference to the rostrum 

 being bent under the breast, and lying in the groove called the rostral 

 canal. N.A. si)ecies : Cri/ptorJiynchus, Illiger, 11; Acalles, Sch., 3; Pseu- 

 flomus, Sch., 1 ; Analcis, Sch., 4. 



Subfamily CEUTORHTNCHIDES. 



Eostrum cylindric, not thickened at base ; scrobes lying along the 

 inferior edge of the rostrum, rarely very oblique. The rostral canal 

 varies in the different groups, as shown below. Scutellum wanting or 



1 indistinct. The three intermediate segments of the abdomen strongly 

 arched. Tibiiie unarmed. The name means the same as that of the 

 preceding sub-family, and implies that the rostrum is more or less con- 



' cealed, but the prosternal groove is here usually less distinct, and some- 

 times wanting. They are chiefly distinguished from the Cryptorhyn- 

 chides by the absence of scutellum, and of points at the end of the 

 tibia, and by the abdominal segments strongly arched behind. They 

 are small insects, found mostly on low herbage in wet places. The 

 habits of the larva' are various, some inhabiting seeds, and others the 

 stems or roots of plants. The Monouychi transform on the plant, whilst 

 the Oeutoryuchi go into the ground and enclose themselves in cocoons. 

 The species are numerous, and are divided by Lacordaire into three 

 groups, as follows : 



A. Eyes covered, at least partly, by tlie tborax. 

 B. Eo8tral canal extendinfr onto the nicsustcnnmi. and sonirtiines the mctastcrnum. . .Caa.lOMitES. 

 B B. Kostral can:il not exti-nding bcy.mil tlio anterior coxa> Ckutorhynciiidks pniper. 



I A A. Eyes exposed. Eostral canal indistinct or wanting Pii vtobudks. 

 In the first group we have one species of the genus Mononychus, Ger- 

 mar, the 2f. riiliwcuhus, Fab., found on the flowers of the wild Iris, and 

 five species of ddiodes, Sch. lu the second group, Ceut<>rhy)H-huii, 

 Germar, 5 species. In the third group, Phytobim, Sch., 3 species; 

 Gcelogmtevy Sch., 1 species ; and RhinoncuSy Sch., 1 species.
