Indiana. 



The description is taken from the male. The species resembles 

 cinnamopterum, but differs in many characters, chief!}- mentioned 

 in the table, but also in its shorter and more robust legs. The 

 punctuation at the sides of the prothorax is coarser and sparser, and 

 the terminal joint of the antenna; is quite different, being shorter 

 and without a well-marked cylindrical process at apex ; the basal 

 joint, also, is much shorter, although this latter character is less 

 important. 



HYLOTRUPES Serv. 



The following species has been well known in our cabinets for 

 many years, and has given rise to much discussion as to its proper 

 value. It is generally conceded to be a well-marked variety of 

 ligneus, but certain characters not heretofore dwelt upon lead me 

 to believe that it is specifically distinct. 



H. litigiosus 11. sp. — Black, shining, the pubescence rather long, sparse ; 

 elytra with two transverse fascise, one before basal third, the other just behind 

 the middle, both broadly interrupted at the suture and not attaining the lateral 

 margins. Head as in li<jnens. Prothorax nearly as in ligneus, but slightly 

 larger. Elytra parallel in the female, distinctly attenuate from base to apex 

 in the male, subdepressed. Length 9.0-12.0 mm. ; width 3.0-4.3 mm. 



California. 



The principal distinctive features of this species, apart from color, 

 are the following : — 



1 — The prothorax is relatively larger and the elytra distinctly 

 narrowed from the humeri to the apex in the male, the latter being 

 shorter and nearly parallel in the corresponding sex of ligneus. 



2 — The elytral pubescence is longer and rather finer, and the 

 punctures do not become so decidedly finer and closer toward apex, 

 this character applying more especially to the male. 



3 — The intermediate tarsi of the male of lignevs are robust or 

 subdilated, with the second joint about as wide as long, while in 

 the same sex of litigiosus they are slender, with the second joint 

 fully one-half longer than wide ; corresponding differences are 

 observable also in the anterior tarsi of this sex, the second joint 

 being strongly transverse in ligneus, and scarcely wider than long- 

 in litigiosus. 



It is difficult to believe that these differences merely indicate 

 varietal modification, especially as they are confirmed by ample
