124 LENG AND HAMILTON. 



LAVithout close inspection this species may readily be mistaken for 

 some of the forms of alpha; the elytra are moderately coai'sely and 

 rather closely punctured to apex, on each are thi-ee slightly elevated 

 lines the inner and outer of which unite before the apex ; on these 

 and also along the suture are spai'sely placed, minute tufts of erect 

 black scales, the two bands on the elytra while not arcuate, are very 

 widely angulate. These characters are taken from the forin xan- 

 ihoxyli. Breeds in the wood of dead prickly ash (Shinier .] " Ham." 



[L.. sclnvarzi n. sp. Length 6.5 mm. ; .20 inch. 



Very robust, elongate, convex, brownish when denuded, densely clothed with 

 fine whitish gray pubescence concealing the punctures; antennje a little longer 

 than the body, incisures black, upperside spotted ; thora.x wider than long, basal 

 constriction deep, the tubercles on each side small and pointed, pubescence dense, 

 punctulation fine and close, disc with a tuben^le on each side of middle behind 

 front margin and one on the centre; scutellum rounded, ))ubescent; elytra with 

 margin, suture and four slightly elevated lines on each bearing remotely placed 

 black dots, humeral angles polished black ; stripe on margin obscure by denuda- 

 tion, at apical fourth a conspicuous, arcuate, black bajid attaining the sides, be- 

 hind this another obscurely fuscous, punctuation fine evanescent toward the apices, 

 which are obliquely truncate; legs luteous, femora fuscous at middle, tarsi and 

 apex of tibiae black, abdomen finely punctured, pubescence rather sparse. 



Described from a single example taken at Key West, Florida, by 

 Mr. E. A. Schwarz, and now in his collection.] " Ham."

 Cinerens is here united to alpha. The distinction as given by Dr. 

 Horn is feeble : 



Surface finely punctured, behind the band almost impunctured iilplia. 



Surface more coarsely punctured, behind the band very distinctly so-ciiioreus. 

 Sets can be selected with the above characters, but between them 

 in a large series many gradations occur which, without violence, 

 cannot l)e assigned to either. The individuals are protean in f(u-m, 

 size, sculpture, vestiture and color, and the result of attempts to 

 separate them into races has not been satisfactory. Say desci'ibes 

 the species as follows : 



" Elytra each witli a white oblique line extending backwards from the middle 

 of the suture. Body dull reddish brown; head longitudinally deeply indented 

 on the vertex ; antennre considerably longer than the body ; incisures blackish ; 

 thorax above destitute of tubercles, but with three small black spots placed 2, 1;
