 and Monterey), Wickham errans n. sp. 



The eyes in many of the Mexican species, and particularly in ^rypus, 

 are somewhat larger ilian in the American, and diflttr notably in having 

 their surface raised above the general surface posteriorly and in having 

 their facets gradually smaller anteriorly ; there seems to be no other very 

 marked structural difference however. Sibinioida, hispidiilus, transversus, 

 mica and inermis are more or less isolated species, not closely related to 

 anything described above. Simplex, from El Paso, Texas, is represented 

 at Tu<;son, Arizona, by a form which is almost identical but materially 

 smaller in size and with the pronotal punctures less densely crowded, each 

 bearing a slender strigose scale, which is narrower than in the more 

 typical form and more isolated.* 



Tribe C ION INT. 

 Miatus Sell. 

 The species of this tribe are very abundant in Kurope ; but tlius far 

 the only genera recognized as occurrin}^ in America .ire represented by 

 single species, which are importations in Naiiophyfi, Cionus and 

 Gym/utron, but indigenous in Miarus. Gymtutroti teter IvJ)., as written 

 by LeConte, or tetrnm, as given in the recent European catalogue, is 

 abundant and rather widely diffused in our eastern States ; it varies 

 enormously in size. In contradistinction to the other genera of the group, 

 Miarus is well represented in America, and our species, as far as known 

 to me, may be described as follows : 



Prothorax with the erect sparse hairs extremely long, bristling and conspicu- 

 ous. P.ody stout, oblong, convex, deep black throughout, the sparse 

 vestiture hairy and cinereous ; beak slender, slightly arcuate, similar in 

 the sexes though a little shorter in the male, longer than the head and 

 prothorax in the female; eyes widely separated ; prothorax nearly as 

 wide as the elytra, very strongly narrowed from base to apex, with 



•The species described by Mr. ScliajfTer (Journ. N. Y. Knt. Soc., 1908, p. 219) 

 under tho name ulhUus, evidently belongs to the siiliatuliis-dulcis type, but is 

 nnah larger than i/n/ris, and wiili .1 diflVrent elylral pal lorn of large scales. Of 

 7". xu/unilis Sc\\f., (I.e., p. --iS), I have a sniail specinjen from Alpine, Texas; it 

 would appear to be rather ;» Sihiuiti than a Tyrhius, though these two genera 

 are not dehnable very well in the .\merican fauna. It has the outline of the 

 Kuropean Sihinia and of oui own S. fiilva, and should undoubtedly be associated 

 uith the latter species wl>ercsoever they n>ay uliimately be assigned.
