CLEONUS. 99 
3. Cleonus aztecus, sp.n. (Tab. VII. fig. 2.) 
Subovate, convex, robust, rather shining, black, thickly clothed with cinereous pubescence ;. the prothorax 
with the apex and a broad space down the middle, and the elytra each with two fascize on the disc, 
almost glabrous. Rostrum short, very stout, dilated at the tip, flattened above, coarsely punctured, with 
the interspaces densely, minutely punctate, obsoletely carinate. Prothorax broader than long, the sides 
(as seen from above) subparallel from the base to near the apex, and then abruptly and obliquely 
converging; the surface uneven, coarsely, irregularly punctured, with the interspaces densely, minutely 
punctate; the anterior margin simply sinuate opposite the eyes, the vibrissee long. Elytra moderately 
long, oval, widest about the middle ; coarsely seriate-punctate, the interstices narrow, almost smooth. 
3, 5 and 7 costate, 5 not callose towards the apex. Beneath somewhat coarsely punctate; ventral 
segments 1 and 2 broadly depressed down the middle. Tarsi with small spongy-pubescent pads beneath ; 
claws free. 
Length 83-94, breadth 4-43 millim. (¢.) 
Hab. Mexico, Refugio in Durango (Hége), Sierra de Durango (Lohr). 
Two specimens. This insect differs from the other Mexican forms in having the 
tarsal claws free and the alternate elytral interstices costate. In general structure it 
is not unlike the European C. quadrivittatus, Zoubk., which also has free tarsal claws.

5. Cleonus lobigerinus. 
Cleonus (Cleonidius) lobigerinus, Casey, Ann. N. York Acad. Sci. vi. pp. 187,191". 
Hab. Nortu America, Southern California and Arizona!.—Mexico, Villa Lerdo in 
Durango, Mexico city (Hove). 
Three specimens, probably belonging to this species. The two from Villa Lerdo 
are almost uniformly clothed with cinereous pubescence, the sides of the prothorax 
only being bordered with a whitish vitta. The one from Mexico city is very like a 
Californian C. lobigerinus, sent me by Mr. Wickham. All have prominent ocular 
lobes to the prothorax and short vibrisse.
