108 RHYNCHOPHORA. 
12. Lixus semivittatus. 
Livus semivittatus, Casey, Ann. N. York Acad. Sci. vi. pp. 197, 207°. 
Hab. Norva America, Utah, Arizona !.—Mextico, Northern Sonora (Morrison). 
Sent to us in numbers by Morrison under the name of L. perforatus, Lec., as from 
Sonora, but agreeing better with the description of ZL. semivittatus, Casey, which is 
perhaps nothing more than a form of Leconte’s species, We also have a specimen of 
it from Arizona, sent to us by Mr. Wickham as JL. pleuralis, Lec., which, following 
Casey, is a Cleonus, and has a shorter second joint to the funiculus. 
13. Lixus caudatus, sp.n. (Tab. VII. figg.7, 7a, 2.) 
Very elongate, narrow, subcylindrical, shining, black or piceous, the antennz and tarsi reddish; clothed with 
rather long fulvo-cinereous pubescence, which is somewhat mottled on the elytra. Head foveate between 
the eyes, rugosely punctured; rostrum curved, comparatively slender, longitudinally rugose, in the 
© strongly curved and about as long as the prothorax, slightly shorter in the ¢; eyes convex, prominent; 
antenne inthe ¢ inserted before, and in the 2 at, the middle of the rostrum, joint 2 of the funiculus 
slightly shorter than 1. Prothorax longer than broad, narrowing from about the middle ; closely, rather 
coarsely punctate, with the narrow interspaces rugulose, obsoletely carinate from the base to before the 
middle, and also shallowly sulcate at the base. Elytra scarcely wider than the prothorax, subparallel 
in their basal half and gradually narrowing thence to the apex, the apices strongly caudate, the basal 
margin raised, projecting a little at the sides; deeply seriate-punctate, the interstices narrow, rugulose, 
and almost flat. Beneath finely punctate. First ventral segment unimpressed in both sexes. Legs 
slender. Body winged. 
Length 93, breadth 2 millim. (¢ 2.) 
Hab. GuatEMata, Duefias, Capetillo (Champion). 
Three specimens. In this and the following species the larger punctures of the 
prothorax are so closely placed that the minute interstitial punctuation is scarcely 
visible ; the rostrum is slender and rugose; the eyes are prominent; and the second 
joint of the funiculus is shorter than the first. The strongly caudate elytra, the more 
rugose rostrum in the female, &c., separate it from L. nigrinus. 
14. Lixus nigrinus, sp. n. 
Livus nigrinus, Sturm, in litt. 
Very elongate, narrow, subcylindrical, shining, black, the antenne and tarsi more or less rufescent; finely 
cinereo-pubescent, the pubescence mottled on the elytra. Head rugosely punctured ; rostrum slender, 
curved, in the ¢ almost as long as the prothorax and rugose to near the tip, in the 9 a little longer 
and with the apical half much smoother ; eyes prominent; joint 2 of the funiculus slightly shorter than 1. 
Prothorax rather longer than broad, narrowing in front; closely, somewhat coarsely punctate, not or very 
feebly depressed at the base. Elytra scarcely wider than the prothorax, subparallel to about the middle, 
the basal margin raised, projecting a little laterally, the apices separately produced, the suture appearing 
to be emarginate at the tip; seriate-punctate, the interstices flat and finely rugulose. First ventral 
segment unimpressed in both sexes. Body winged. 
Length 63-11, breadth 14-21 millim. (¢ @.) 
Hab. Mexico (Sallé, ea coll. Sturm), Orizaba (Sallé), Almolonga, Acapulco (Hége), 
Temax in N. Yucatan (Gawmer); British Honpuras, Rio Hondo (Blancaneauz) ; 
GUATEMALA, San Gerdnimo, Duefias (Champion).
