LIXUS.—STERNECHUS. 113 
Jekel (=vittatus, Jekel, olim), from Venezuela, and L. sulcatus, Kirsch, from Colombia, 
are allied forms: the first-mentioned has the alternate elytral interstices depressed, the 
eyes more transverse, and the anterior femora dentate; the other has the first elytral 
stria flattened and very broad, the anterior femora obtusely angulate, &c. 
ILEOMUS. 
Larinus, subgen. Ileomus, Schénherr, Cure. Disp. Meth. p. 220 (1826). 
Ileomus, Schonherr, Gen. Cure. iii. p. 145; Lacordaire, Gen. Col. vi. p. 440. 
A genus scarcely separable from Lixus, and including a few Tropical-American forms, 
those from the Caucasus, &c., probably belonging elsewhere. 
1. Tleomus distinguendus. (Tab. VII. figg. 16, 16a, 2.) 
Ileomus distinguendus, Boh. in Schénh. Gen. Cure. vil. 2, p. 3’. 
Hab. Mexico, San Andres Tuxtla, Orizaba, Vera Cruz! (Sal/é); British Honpuras, 
Cayo, Belize (Blancaneaux); GuatemaLa, El Reposo, Teleman, Panzos (Champion) ; 
Nicaragua, Chontales (Belt, Janson); Panama, Bugaba (Champton). 
We possess a long series of this insect, which is very like the South-American 
I. mucoreus (Linn.), and perhaps not really distinct from it. The females have a much 
more elongate rostrum than the males, and the latter have the first ventral segment 
depressed down the middle. The anterior and intermediate femora are dentate. 
Group STERNECHINA. 
Hylobiides, groupe II. Sternéchides, Lacordaire. 
This group includes a single genus, Sternechus, Schonh. (= Tylomus, Schénh.), which 
Lacordaire refers without hesitation to the Hylobiina, the subconnate tarsal claws 
notwithstanding, a character common to most of the Cleonina, near which it seems 
best placed. The species are very like the Australian Gonipterina. 
STERNECHUS. 
Sternechus, Schénherr, Curc. Disp. Meth. p. 251 (1826) ; Gen. Cure. ili. p. 472 ; Lacordaire, Gen. 
Col. vi. p. 447. 
Sternuchus, Gemminger and Harold, Cat. Col. viii. p. 242. 
Tylomus, Schénherr, Curc. Disp. Meth. p. 253 ; Gen. Cure. iii. p. 477; Lacordaire, Gen. Col. vi. 
p. 448. 
Sternechus and Tylomus are connected by intermediate forms, there being a gradual 
transition from one to the other in the armature of the tibie, and also in the relative 
length &c. of the antenne. 4. drevicollis greatly resembles the Cryptorrhynchid-genus 
Chalcodermus, some species of which have an angular prominence at the sides of the 
BIOL. CENTR.-AMER., Coleopt., Vol. IV. Pt. 4, December 1902. QQ
