116 SUBFAMILY IX. OTIORHYXCHIXJE. 



150 (8297). GEODEKCES MELANOTHRIX Kirby, 1837, 202. 



Oval, robust. Chestnut brown, densely clothed with dirty brown scales, 

 with a line on sides of thorax and short indistinct markings on elytra 

 paler, the saales intermixed with very short, semi-erect sparsely placed 

 blackish Iiairs; antennae reddish-brown. Head and beak slightly longer than 

 thorax, beak coarsely, sparsely punctate. Thorax oval, slightly wider than 

 long, disc coarsely, sparsely and evenly punctate. Elytra oval, narrowed at 

 base, subglobose, humeri oblique; disc with striae of moderate punctures; 

 body beneath coarsely punctured and sparsely scaly; legs densely covered 

 with brownish scales, femora with a broad ring of whitish scales near the 

 tip. Length 5.5 8 mm. 



Ranges from Canada and New York to Lake Superior and 

 Vancouver, B. C. A member of the Boreal and Transition Life 

 Zones. 



Division II. OTIORHYNCHIXJE ALATJE. 



The species of Division II are called Otiorhynchina? Alatoe in 

 the Biologia, though the wings are sometimes rudimentary even 

 in a series of specimens of certain species (e. g. Tanymecus con- 

 fertus) from the same locality. In addition to the characters of 

 the key, the shoulders of the elytra are distinct and stand out 

 more or less laterally, the tip of the scutellum separates the ex- 

 posed bases of the elytra, and the metasternum is either elongate 

 or short. 



Of the metasternal episternum in this Division Horn (1876, 

 SO) says : "It is usually moderately broad, the suture distinct 

 in its entire length. In every case, however, the front end of the 

 episternum is suddenly dilated, causing on one side an emargina- 

 tion of the elytral margin (which is, however, evanescent), while 

 on the inner side an acute triangular process of varying length 

 occupies a space between the mesosternal epimeron and the body 

 of the metasternum." The rnandibular scar is very distinct in 

 all the genera and is usually on the face of the mandible itself, 

 though sometimes at the summit of an obtuse process. Most of 

 our members of the Division have the body proportionately more 

 elongate and slender than those of Division I, but the form in 

 Sciaphilus and Strophosoma is quite similar to that commonly 

 observed in Division I. The five tribes recognized by Horn are 

 represented in our territory . 



KEY TO EASTERN TRIBES OF DIVISION n. 



a. Thorax without ocular lobes (present but feeble in Pachnccus) ; men- 

 turn of moderate size, not retracted; eyes rounded or oval. 

 b. Thorax with a fringe of short bristly hairs on the front margin 

 behind the eyes; elytral striae ten. Tribe I. TANYMECINI, p. 117. 

 bb. Thorax without fringe of hairs as above.
