240 GEO. II. HORN, M. D. 



By some accident the nieasureuiont civen (Trans. Am. Ent Soc, 

 1875, p. IGl), is incorrect, it should be .38 inch, not .02 as printed. 



C {;ratio!«a, Guerin. 



The description and figure in the synopsis suffice to distinguish 

 this species. 



The group cupt-ascens, through its members exhibits affinities in 

 many directions. The group as a whole, naturally follows the ffor- 

 salis and marglnata groups ; Miir/<hife)ifTe seems to me to point to- 

 ward leplda, sperata toward Gahbii, and grutiosa toward togata 

 and its allies. 



The presence of the sutural vitta is of rare occurrence in our 

 fauna, being present oily in Magda/nifie and leplila. In these two 

 species it exists as an independent marking, and is in no way similar 

 to the dilated humeral lunule of dorsaiis. 



C Scliauppii, n. sp. — Head and thorax dark bronze, sparsely hairy. 

 Elytra velvety black. Body beneath metallic blue, sides of metasternum 

 brilliantly cupreous, entire abdomen and j)osterior trochanters red. Labrum 



B white, !<lightly longer in 9> truncate at middle and slightly sinuate 

 each side. Eyes moderately prominent, head slightly strigose near the 

 eyes. Thorax slightly narrowed behind, impressions distinct. Elytra 

 with velvety surface, smaller punctures obsolete, a row of larger green- 

 ish punctures ne^r the suture and others near the humerus; margin 

 narrowly white, slightly dilated at the humerus and again behind it, 

 median band reduced to a straight, oblique line, apical lunule slightly 

 prolonged in front. Legs bluish green, femora cupreous beneath. Length 

 .42 inch ; 10.5 mm. 



The elytra at tip are conjointly rounded, very finely serrulate, and 

 the suture slightly spinous. 



This species belongs near circmnplcta and prselvxtata, and resem- 

 bles the latter considerably in its markings, but differs in its entirely 

 red abdomen. It also differs from nearly every other red-abdomen 

 species in the entire absence of any labruui tooth. 

 Two specimens, Corsicana, eastern Texas. 



It gives me great pleasure to dedicate this species to Mr. F. G. 

 Schaupp, of Brooklyn, and at the same time acknowledge my in- 

 debtedness for this and many other very interesting additions to 

 my cabinet.
