LIXUS. 109 
Sent in plenty from Yucatan. The smallest of the Central-American species, and 
differing from the preceding as noted above. ‘There is a specimen of it from Orizaba, 
labelled with the MS. name JL. tenuis, in the British Museum. 
§ 2. Wings absent or rudimentary. 
15. Lixus germari. (Tab. VII. figg. 8, 8a, 2.) 
Lixus germari, Boh. in Schénh. Gen. Cure. vii. 1, p. 455 *. 
Hab. Mexico}, Sierra de Durango, Teopisca, Motzorongo (Flohr), Toxpam (Sa/llé), 
Teapa (H. H. Smith). 
Not rare in North-western, Central, and Eastern Mexico. This species, which is 
broader and more convex in form than any of the other Central-American members 
of the genus, has the triangular scutellum* depressed almost to the level of the 
mesonotum (and only visible when the prothorax is separated from the elytra), and 
the wings are rudimentary. The elytra are here and there transversely depressed on 
the disc, and, when covered with efflorescence, bifasciate. The rostrum is very stout 
and strongly curved, and very little longer in the female than in the male. The first 
ventral segment is sulcate down the middle in the male. Length 124-18, breadth 
1 el mili 
4-64 millim. 
16. Lixus porcatus. 
Lizus porcatus, Boh. in Schénh. Gen. Cure. vii. 1, p. 424°. 
Hab. Mexico (Sallé; Mus. Brit.), Mineral del Zimapan 1. 
There is a single female specimen of this species in the Sallé collection. It may be 
known amongst the forms with a depressed submarginal vitta by the alternate dorsal 
interstices of the elytra being raised and widened, and the strie placed in double 
series. Length 15 millim. 
17. Lixus mexicanus. (Tab. VII. figg. 9, 9a, 2.) 
Lizus mexicanus, Boh. in Schénh, Gen. Cure. vii. 1, p. 426°. 
Hab. Mexico ! (Mus. Brit.), Milpas and Ciudad in Durango (Forrer), Xucumanatlan, 
Omilteme, and Amula in Guerrero (H. H. Smith), Cuernavaca, Juquila, Parada, | 
Oaxaca, Istepec (Sallé). 
Numerous specimens are referred to this perplexing species: four of them (¢ @ ), 
from Oaxaca, one of which is figured, have the elytra attenuate and acuminate at the 
apex, as described by Boheman, but in the others (twenty-three in all) the apices are 
much less produced. The sculpture of the upper surface is variable, the prothorax 
* Boheman describes L. germari as having a small, rounded, shining scutellum; but this must be an error 
of observation, due, probably, to the type having been partially covered with efflorescence.
