NOKTH AMKHICAN COLKOPTERA. li) 



Occurs from New Hampshire westward tlirough New York and 

 Canada to Michigan and Colorado. 

 A. lon$;iila Lee. 



Narrower and more elongate than the other species, and with the 

 thorax more narrowed in front. The hind angles of the thorax are 

 rectangular, and the oblique impression of the disc very indistinct. 

 The sides of the body beneath are coarsely, but sparsely punctate. 



Occurs on the Pacific coast from Washington southward to San 

 Diego. 

 A. scitula Zimm. 



Broader than longula, and with the sides of the thorax more ar- 

 cuate. The hind angles of the thorax are less sharply rectangular, 

 and the oblique impression entirely wanting. The body beneath is 

 obsoletely punctate at the sides. The femora are always piceous and 

 more or less metallic, the tibire and tarsi paler, but never rufo-testa- 

 ceous. 



Occurs from Washington to San Diego. 



A. Belfragei \\. sp. — Oval, piceous moderately shining, surface faintly 

 bronzed. Antennae entirely rufo-testaceous. Thorax half wider than long, 

 sides arcuately narrowed to the front, hind angles slightly obtuse, surface smooth 

 and shining, impunctate, basal region with extremely vague traces of impres- 

 sions. Elytra finely striate, more deeply at apex, lateral strise, sixth and sev- 

 enth, almost obliterated. Body beneath piceous. smooth, shining, slightly me- 

 tallic, epipleuriB a little paler. Legs rufo-testaceous. Length .32— .34 inch.; 

 8—8..^ mm. 



This species very closely resend)les impuncticollts, but niay be 

 known by the form of the spur of front tibia. It is more oval than 

 any species of the Tricena series, and differs from them all by the 

 entirely pale antennsje. 



Collected by Belfrage at Waco, Texas. 



A Ntiul.^' of AMAR.A s. g. CELIA. 

 BY (;E0. II. HORN, M. D. 



The division or sub-genus Celia was first proposed by Zimmer- 

 man n for those An)ame in which, with a thorax broad at base, the 

 posterior tibine of the males are not pubescent on the inner side. The 

 memoir by Zimmermann was published in the first volume of Gistl's 

 Faunus, 1882, and two years later a French translation appeared in 

 the second volume of Silbermann's Revue. These two works are 

 practically inaccessible to the vast majority of American stu<lents, 

 and very few libraries contain either work.
