SNOUT-BEETLES OR WEEVILS. 
143 
base of rostrum ; scope at most reaching the eyes. Rostral canal ex- 
tending onto the mesosternum. Eyes large, pointed interiorly. Ocular 
[Fig. m.] lobes more or less prominent. 
Thighs sometimes toothed beneath. 
Tibiae spined at the end. In Cryp- 
torhynchus proper the tibiae 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 
is of various for,n > and is usually 
of beetle after Eiiey. clothed with scales. The family 
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 : Gryptorhynckus, Illiger, 11; Acalles, Sch., 3; Pscu- 
(lomus, Sch., 1 ; ' ' ' “ 
Analcis, Sell., 4. 
Sub-family CEUTOK LI YNC II IDES. 
Rostrum cylindric, not thickened at base; scrobes lying aloug the 
inferior edge of the rostrum, rarely very oblique. The rostral canal 
varies in the different groups, as shown below. Scutellum wanting or 
indistinct. The three intermediate segments of the abdomen strongly 
arched. Tibife 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 prosterual groove is here usually less distinct, and some- 
times wanting. They are chiefly distinguished from the Crypt-orhyn- 
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 Mononyclii 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. 
13. Rostral canal extending onto the mesosternum, and sometimos the iuotastonnnnJL.On'.i.iomnKS. 
13 13. Rostral canal not oxtonding beyond the anterior coxa* CiiUToiuiY^riiiDHs proper. 
A A. Eyes exposed. Rostral canal indistinct or wanting Phytobiidks. 
In the first group we have one species of the genus Moydmychus , tier- 
mar, the M. vulpeculus , Fab., found on the flowers of the wild Iris, and 
five species of Gwliodes, Seh. In the second group, Geutorliynchus , 
Gennar, 5 species. In the third group, Pliytobius , Seh., 3 species; 
Ccelogaster, Sch., 1 species ; and Mhinoncus , Sch., 1 species.
