LIXUS. 105 
Prothorax as long as or longer than broad, conical, densely, minutely punctate, with intermixed coarser 
punctures, the basal depression small and shallow. Elytra very elongate, a little wider than the prothorax, 
subparallel for three-fourths of their length, the apices slightly dehiscent and acuminate, the common 
basal depression shallow ; seriate-punctate, the interstices flat, finely rugulose. First ventral segment 
unimpressed. Body winged. 
Length 123-154, breadth 3-32 millim. ( 9.) 
Hab. Mexico, Puebla (Sallé), Amula (H. H. Smith). 
Three specimens, probably all females: the one from Amula has a white submarginal 
vitta, the prothorax longer than broad, and the rostrum sparsely punctured towards the 
tip; the two from Puebla, which are covered with efflorescence, have the rostrum 
densely rugulose to near the apex, and the elytra without trace of a submarginal vitta. 
They possess in common, however, a very shallow depression at the base of the pro- 
thorax, a character separating them from the nearly allied LZ. inermis. The rostrum 
is comparatively slender. " 
6. Lixus toltecus, sp. n. 
Very elongate, narrow, cylindrical, shining, black, the antenne partly rufescent; finely cinereo-pubescent, the 
pubescence mottled on the elytra, and with a condensed whitish submarginal vitta on the prothorax and 
towards the apex of the elytra. Head shallowly foveate between the eyes, in the ¢ closely punctate, 
with coarser punctures intermixed, in the 2 sparsely punctured ; rostrum in the ¢ moderately stout, 
about as long as the prothorax, feebly curved, and closely, longitudinally rugulose almost to the tip, in 
the 2 slender, distinctly longer than the prothorax, strongly curved, sparsely punctured from the base 
to near the middle and almost smooth thence to the apex ; antenne in the ¢ inserted considerably before, 
and in the 2 a little behind, the middle of the rostrum, joint 2 of the funiculus slightly shorter than 1 
in both sexes. Prothorax convex, rather broader than long, subconical, strongly bisinuate at the base ; 
closely, minutely punctate, with intermixed coarser punctures, the basal depression small and extending 
forward. Llytra very elongate, of the same width as the base of the prothorax, subparallel for two-thirds 
of their length, somewhat acuminate at the apex, the common basal depression shallow ; seriate-punctate, 
the interstices flat and finely rugulose. First ventral segment unimpressed in both sexes. Body winged. 
Length 93-11, breadth 23-25% millim. (¢ 2.) 
Hab. Mexico, Puebla (Sal/é), Atlixco in Puebla (Hége). 
Two males and two females. In this small species the sexual difference in the form 
of the rostrum is almost as strongly marked as in L. fimbriolatus, that of the female 
being slender, moderately long, strongly curved, and almost smooth beyond the middle. 
In general shape L. toltecus resembles L. nigrinus, which, however, is not a very nearly 
allied form. 
7. Lixus subcaudatus. 
Lizus subcaudatus, Boh. in Schénh. Gen. Cure. vii. 1, p. 428°. 
Hab. Mexico! (Sallé, ex coll. Sturm'), Durasnal, Orizaba, 'Toxpam, Parada, Juquila 
(Sallé); Guatemaa, Coban (Conradt). 
This species is somewhat fusiform in shape, with the elytra elongate, flattened on the 
disc, and acuminate at the apex; the prothorax and elytra with a narrow submarginal
