Mr. Charles J. Gahan, in his recent valuable contribution : 

 "Notes on Cleridse and Descriptions of some new Genera and 

 Species of this Family of Coleoptera." (Ann. Mag. Nat. 

 Hist., Lond., Ser. 8, Vol. V, Jan., 1910, pp. 55-78), calls at- 

 tention to the fact that the North American species, Thancro- 

 clerus sanguinens Say. differs from the genus type (E. bu- 

 queti Lefebvre) in several important details of structure; 

 these differences are of sufficient moment to necessitate the 

 erection of the following new genus : 



ZENODOSUS gen. nov. 



Eyes oval, finely granulate, entire ; front coxal cavities open 

 behind; flanks of prothorax non-carinate. 



Type of the genus Zenodosus (Thaneroclerus) sanguinens 

 Say. 



In Thaneroclerus Lef., the eyes are small, feebly emargin- 

 ate, round and coarsely granulated, the flanks of the prothorax 

 distinctly carinate, and the front coxal cavities closed behind. 



An examination of material in my collection shows, how- 

 ever, that the Cuban species (T. girodi Chevrolat), is a true 

 Thaneroclerus. 



Clerus ichneumoneus Fabr. var. knabi nov. 



Form, size and sculpture as in typical form, the markings and color 

 also similar, hut with the apical fourth of elytra pale reddish testaceous, 

 each elytron with a rather large, ante-apical, black maculation. Length 

 11.5 mm. 



Marion Co., Florida. 



This variety, if indeed such it be, was sent me several years 

 ago by Mr. Frederick Knab, since which time I have examined 

 not less than four hundred specimens of ichneumoneus with- 

 out finding another individual either identical with, or inter- 

 mediate between this and the typical form, hence knabi may 

 eventually prove to be a distinct species. 



Hydnocera maritima sp. nov. 



Elongate, feebly shining, olive-green; head and thorax aeneous; an- 

 tennae, labrum, palpi, knees, tibiae and tarsi testaceous. Head (in- 

 cluding the moderately prominent eyes) very slightly wider than the 

 thorax, coarsely, densely rugose. Thorax one-third wider than long,
