ITHAURA.—THEOGNETE. . 97 
Hab. Mexico, San Antonio de Arriba (Salié). 
One specimen. Differs from J. pinicola in the more convex shape, the feebly 
constricted, shorter rostrum, and the sulcate, finely seriate-punctate elytra. The 
anterior tibia are without a median tooth. 
THEOGNETE, gen. nov. 
Antenne with the funiculus 7-jointed, joints 3-7 transverse and gradually widening, 7 closely articulated 
to the club, the latter short-ovate, pointed at the tip, the first joint shining and the others dull and 
pubescent; head globose, smooth; rostrum stout, constricted at the base, slightly widened in its apical 
half, the scrobes deep, lateral, descending to beneath the eyes, the anterior opening just visible from 
above; the eyes placed at the sides of the rostrum behind, oval, coarsely facetted ; prothorax trans- 
versely convex, with a transverse sulcus before the anterior margin beneath, visible at the sides above, the 
prosternum very short; anterior cox somewhat widely separated; intermediate coxe widely separated, 
the mesosternum transversely sulcate between them; metasternum extremely short; posterior cox 
inserted near the outer margin of the body, and narrowly separated from the intermediate pair; scutelium 
absent ; elytra connate, gibbous, cordiform ; ventral segments 1, 2, and 5 subequal in length, 3 and 4 
exceedingly short, 1 and 2 connate, the first suture sinuous; legs short and stout; tibie slightly sinuate 
within, not dilated at the tip, mucronate at the inner apical angle, and armed with a curved claw at 
the apex, the lower apical margin furnished with several fine tecth ; tarsi very short, feebly developed, 
sparsely pilose beneath, the third joint bilobed, the claws extremely minute, free. 
The single species referred to this genus has somewhat the facies of a Liosomus or a 
minute Liparus. It is a very remarkable form, wholly different in appearance from 
Dioptrophorus, to which Theognete is nearly related. ‘The tarsi are very small and 
short, compared with the powerful femora and tibie. ‘The anterior coxe are a little 
more widely separated than in any of its nearest allies. 
1. Theognete levis, sp.n. (Tab. VI. figg. 29, 29 a, 6.) 
Obovate, very convex, shining, black, the tarsi and the antenne in part rufescent; the prothorax and elytra 
with a few, widely scattered, appressed, long, coarse, piliform, flavescent scales ; the legs with similarly- 
coloured short hairs. Rostrum nearly as long as the prothorax, coarsely and closely punctured ; the 
-antenne inserted at about the middle. Prothorax as long as broad, constricted at the apex and narrowed 
‘behind, the sides slightly sinuous in one specimen; the surface smooth, with minute scattered squami- 
gerous punctures. Elytra short, gibbous, with the apices produced and conjointly rounded, about 
one-half longer, and much wider than the prothorax, smooth, each with a longitudinal groove near the 
suture below the base, in which traces of seriate punctures are visible. Beneath smooth. Fifth ventral 
segment obliquely sloping from about the middle to the apex, the anterior portion flattened and with a_ 
transverse-oval depression in the. middle, the posterior portion with a transverse depression on each side 
in front and another in the centre behind. 
Length 3, breadth 13 millim. 
Hab. Mexico, Sierra de Durango (Flohr) ; Guaremata, Cerro Zunil (Champion). 
One specimen from each locality, their sex not ascertained. The Mexican individual 
is a little more robust, and has stouter legs, and coarser scattered scales, than the 
Guatemalan insect.
