the under side smooth and shining, opaque and spinulose on the upper 

 surface; palpi of the usual form. 



Prothoracic joint, when viewed from the side, slightly longer than 

 the other two thoracic joints. Dorsally the three thoracic and the first 

 six abdominal joints are essentially alike in length and sculpture; they 

 are triplicate in the usual manner and covered with rather sparse, 

 small, shining tubercles, each giving rise to a stiff, moderately long, 

 blackish spine, directed backwardly; there is also on each joint a 

 more or less regular transverse row of long brownish setse. The last 

 four abdominal joints are much longer, not sulcate and much 

 smoother; the anal joint longer but much narrower than the pre-anal, 

 transversely convex and evenly rounded at tip, its surface is sparsely 

 beset with irregular long setse more densely so at tip. On its under 

 surface and not visible from above, the terminal joint has a trans- 

 verse slit which causes it to appear divided in two parts. Spiracles 

 large, the abdominal ones regularly short-oval in outline, the break m 

 the peritrema very narrow; prothoracic spiracle decidedly larger, 

 more oblong and less regular in outline. 



Legs stout, covered with long but rather sparse setse; second pair 

 thicker and slightly longer than the first; third pair again longer than 

 the second; the claw is short, robust, and subulate at tip. 



Under surface of abdomen more shining, more sparsely tubercled 

 and less spiny than the upper surface. 



The description is made from an alcoholic larva found in a rotten 

 gtump at Wilkesboro, N. C, in the month of June. 



Attention is called to the fact that Dr. Eugene Duges in describing 

 the larva of the Mexican Dynastes Byllus,"^ says, that the larva is dis- 

 tinguished from that of Strategus julianus only by the sculpture of the 

 body and the form of the last abdominal joints. In the former 

 species the abdominal joints and the two posterior thoracic joints are 

 said to be furnished with numerous longitudinal folds (plis), and the 

 terminal joint flattened above so that when viewed from above it 

 appears to be triangular in outline. Keferring to DeHaan's figure of 

 Dynastes hercules,1[ I find the general sculpture and the form of the last 

 abdominal segment to correspond with those of our D. Tityus, and as 

 I know of no Lamellicorn larva having longitudinal folds except from 

 contraction, I half suspect that those in Duges' specimen were 

 unnatural. 



Description of the Pupa. 



Pupa of male. — Covered with a very line velvety pruinosity and 

 therefore opaque. Where the pruinosity is abraded the body appears 

 to be somewhat shining. No distinct sculpture is visible; horns on 

 head and prothorax much thicker and stouter than in the imago, and 

 faintly ringed transversely. Mesonotum and metanotum with a very 

 fine faintly impressed median line. The sutures between the first six 

 abdominal joints are deeply and suddenly depressed, the joints them- 

 selves appearing to be very short and' somewhat gibbous. Base of 

 the first joint as well as the anterior and posterior margin of the four 

 following joints and the anterior margin of the sixth, furnished on
