ANELPISTUS, n. gen. (Melandryidfe.) 



The genus for which the uame is proposed differs from Scotodes 

 Esch. by the following characters : 



Tborax broader than long, sides rounded in front, gradually narrowing to 

 base, hind angles not prominent. Elytra very little broader than the 

 thorax. 



This genus which may be considered the representation of Scotodes 

 in our fauna resembles rather an Emmesa or a convex Phn/ganophllus. 

 It possesses all the other characters of Scotodes even to the form of 

 the tibial spurs, and can be distinguished only by the form of thorax. 

 The latter genus, rare in Europe, is known to me only by the descrip- 

 tions of authors and the figure of Duval (Genera, PI. 86, fig. 429) in 

 which the thorax. is represented as being nearly as long as broad, the 

 sides strongly rounded in front, sinuate behind, with the hind angles 

 prominent. 



A. americanus, n. sp. — ]3rownish-testaceous,slightly shining. Head densely 

 and coarsely punctured and sparsely clothed with cinerous hairs. Thorax 

 nearly black, more shining and less densely punctured than either head or ely- 

 tra and sparsely clothed with cinereous pubescence; one- fourth broader than 

 long, sub-truncate at apex, sides strongly rounded in front but gradually nar- 

 rowing to the hind angles which are not prominent, base truncate with a dis- 

 tinct imj^ression near the middle of the base of each elytron. Elytra elongate 

 l^arallel, moderately convex, densely and coarsely punctured and clothed with 

 cinereous ijubeseence, forming a more distinct band at the middle of each ely- 

 tion very narrow at suture, and also at the apical fourth. Body beneath black, 

 more shining, very finely'' and rather densely punctured, and sparsely clothed 

 with cinereous hair. Legs brownish testaceous tibice with apical and middle 

 third darker. Length .28 "£ — .34 f inch; 7— 8.5 mm, 



The male has the antennae slightly longer owing to a greater elonga- 

 tion of joints 8 — 7. The tibij» are also very distinctly arcuate in % 

 and straight in $ . 



The cinereous hair forming the vestiture of the elytra in the male 

 specimen before me appears to be more densely placed in a band across 

 the middle, broad at margin and rapidly narrowing to suture^ the 

 apical fourth is also more densely clothed. This arrangement of vest- 

 iture may be owing to accident in pinning, as a specimen which had 

 been preserved in alcohol is almost entirely nude. The male is smaller 

 and more slender than the female. 



For the two specimens in my cabinet I am indebted to3Ir. Sanborn, 

 of Boston, by whom they were taken in the White Mountains of New 

 Hampshire.
