"The measurements are taken from the a})ex of the elytra to the 

 anterior margin of the thorax; the smaller sjieciniens are females. A size 

 i.-i thus indicated exceeding any Bostrichide known.'' 



"For tiie fragments in my possession I am in(lei)ted to the untiring 

 exertions of Mr. "\\'. G. Wright, of San Bernardino, Cal., a zealous Botanist, 

 for whom neither the prixations irK'i(k^nt to an exploration of the Mojave 

 Desert nor tiie jealous watchfulness of the Indians, seemed to ha\-e had 

 any terrors." 



"Mojave Desert, California." 



The locality "Mojave Desert" was given Dr. Horn by the 

 eccentrie pioneer naturalist, W. G. Wright, who was a zealous 

 collector but lacked the true scientist's viewpoint of wishing to 

 share his discoveries with the world. Wright was always secretive 

 as to the localities where he found his rare specimens, probably 

 out of fear that others would be led to liis pet hunting grounds. 



Dr. Horn gave a description of the larva of Dinapate wrightii, 

 in the article above referred to. This was as follows: 



".torm robust, convex, the ventral surface flat, gradually narrower 

 from the prothoracic to the last segment, the last four segments recurving, 

 their ventral surface in contact with that of the preceding segments; 

 color whitish, consistence soft. 



Segments twelve; three thoracic, nine abdominal. 



Prothorax large, massive, somewhat narrowed in front, flat above, 

 yellowish white, a dorsal and two lateral fuscous spaces, the latter includ- 

 ing an elevated serrate line; spiracle large, fusiform in outline. 



Meso and Metathorncic segments consisting of a dorsal and infero- 

 lateral piece, the latter as seen from the side larger; these segments with- 

 out spiracles. 



Abdominal segments. The first two consist of two dorsal pieces, the 

 division indicated by a fold merely, the spiracles in these segments smaller 

 than the prothoracic and situated in a rhomboidal depression between the 

 dorsal and infero-lateral plates; segments three to eight gradually less
