Group CLEONINA. 
This group includes Cleonus, Dinocleus, Lirus, and Lleomus, the first two not 
extending south of Mexico. Larinus is altogether absent, possibly owing to the 
limited number of indigenous Carduace, not only from our region, but from the whole 
of America. 
CLEONUS. 
Cleonis, Latreille, Dict. Class. d’ Hist. Nat. xiv. p. 206 (1823) (sine descr.). 
Cleonus, Schénherr, Cure. Disp. Meth. p. 145 (1826); Gen. Cure. ii. p. 171; Lacordaire, Gen. 
Col. vi. p. 430; Leconte, Proc. Am. Phil. Soc. xv. pp. 145, 148; Casey, Ann. N. York Acad. 
Sci. vi. pp. 176, 185. 
A genus including a large number of species, the majority of which inhabit the 
Palearctic region. Capt. Casey recognizes twenty-four North-American forms, two of 
these entering Mexico, whence five are now known. ‘The Palearctic Cleont have been 
grouped under numerous subgenera; the Mexican forms may for the present be 
referred to two—Apleurus and Cleonidius. The prothoracic vibrisse are long in 
C. fossus, C. pulvereus, and C. aztecus, and quite short in C. boucardi and C. lobigerinus. 
In C. aztecus the tarsal claws are free. 
Subgen. ApLeurus, Chevr. (part.) (= CLEonopsis and CLEonasPIs, Lec.). 
1. Cleonus fossus. (Tab. VII. fig. 1.) 
Apleurus fossus, Chevr. Mém. Soc. Liége, (2) v. p. 78°. 
Hab. Mexico 1, Cordova, Esperanza (Hége), Oaxaca (Sallé). 
The type ef this insect, which is not labelled with any definite locality, is contained 
in our collection, and we have six others from Hoge or Sallé. C. fossus is probably 
nothing more than a southern form of C. pulvereus, Lec.; but may be separated by its 
more robust build, stouter rostrum, and coarser sculpture. The largest specimens, 
including the type, are considerably broader than any of the numerous North-American 
or Mexican C. pulvereus before me. The rostrum is sometimes obsoletely carinate. 
2. Cleonus pulvereus. 
Cleonus pulvereus, Lec. Col. Kansas & Hastern New Mexico, p. 18 (1859) °. 
Cleonopsis pulvereus, Lec. Proc. Am. Phil. Soc. xv. p. 147’. 
Cleonus (Apleurus) pulvereus, Casey, Aun. N. York Acad. Sci. vi. p. 186°. 
Hab. Norta Americat, Texas and Colorado?, New Mexico.—Mexico, Durango 
city (H6ége), Sierra de Durango (Flohr). | 
Found in plenty by Hoge, the specimens varying greatly in size and sculpture.
