SNOUT -BEETLES OR ^rEEVILS.

base of rostrum ; scope at most reaching the eyes. Rostral canal ex- 

 tending onto the mesosteruum. Eyes large, pointed inferiorly. Ocnlar 



lobes more or less prominent. 

 Thighs sometimes toothed beneath. 

 Tibite spined at the end. In Cryp- 

 torhynchus proper the tibite have 

 a band of rigid hairs near the ex- 

 tremity, usually bright yellow, but 

 sometimes black. These are small 

 species found on plants. The body

name signifies 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. species: Cryptorhynchus, Illiger, 11; Acalles, Sch., 3; Fseu- 

 donius, Sch., 1 ; Analcis, Sch., 4. 



Subfamily CEUTOEHY^CHIDES. 



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

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

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

 indistinct. The three intermediate segments of the abdomen strongly 

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

 preceding sub-family, and implies that the rqstrum 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 larvae are various, some inhabiting seeds, and others the 

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

 the Ceutorynchi 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 the thorax. 



B. Rostral canal extending onto the mesostermini, and sometimes the metastemum.. CaiLiODiDES. 



B B. Rostral canal not extending beyond the anterior coxa? CEUTOEHYNCmuES proper. 



A A. Eyes exposed. Rostral canal indistinct or wanting Phytobiides. 



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

 mar, the M. vulpeculiis, Fab., found on the flowers of the wild Iris, and 

 five species of CceModes, Sch. lu the second group, Geutorhynchus, 

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

 Gcelogaster, Sch., 1 species ; and Kh'moncus, Sch., 1 species.
