HEMIRHIPUS (p. 271). 

 1 (a). Hemirhipus ferrugineus. (Tab. XXIV. fig. 3.) 



Hemirhipus ferrugineus, Cand. Elat. Nouv. v. p. 15 (1893) *. 

 Hab. Guatemala 1 . 



Dr. Candeze has kindly forwarded the type of this insect for examination. It is 

 extremely like H. bimaculatus, from which it differs in its larger size and much more 

 elongate elytra, the latter with the third and fifth interstices broader than the others 

 towards the apex ; the type of H. bimaculatus is, no doubt, a male, and that of 

 H. ferrugineus a female, the latter having the scutellum abnormally formed. H. ferru- 

 gineus itself is probably a variety of the Colombian H. fairmairei, Cand., with the 

 black markings on the thorax reduced in size ; it is recorded by Candeze himself in his 

 c Catalogue Methodique ' as from Central America. 



The descriptions of Hemirhipus ferrugineus and Chalcolepidius monachus were not 

 seen in time to enable me to insert the species in their proper places. 



CHALCOLEPIDIUS (p. 272). 

 7. Chalcolepidius apacheanus. 



Chalcolepidius apacheanus, Casey, Ann. New York Acad. vi. p. 16 (1891) 1 . 

 Chalcolepidius webbi, huj. op. p. 278, t. 11. fig. 23 (nee Lee.) 2 . 



Hab. North America, Arizona 1 . — Mexico, Chihuahua city (Hoge 2 ). 



Since my remarks on C. webbi were published we have received a beautiful male 

 example of the species from Mr. Wickham, from Yuma, California ; it has the apical 

 joint of each tarsus, and the anterior and intermediate tibiae ciliate *, as in the males 

 of C. lacordairei &c. From a renewed examination of these specimens I am now con- 

 vinced that the abraded Mexican females from Chihuahua referred by me to C. webbi 

 really belong to C. apacheanus, Casey, and that the two insects are specifically distinct. 

 The Mexican specimens, which vary from 28-37 millimetres in length, differ from 

 G. webbi in the relatively longer thorax (in C. apacheanus it is described as one-fifth 

 longer than wide), with the larger punctures on the anterior part coarser and more 

 numerous, and the more deeply impressed head. The few remaining small scales on
