166 THE CANADIAN ENTOMOLOGIST. 



decided to let it stand for the present as a species whicli should go between 

 fulgida and echo (though more closely allied to the former), since the 

 characters used in diagnosis seems absolutely constant in niy series. The 

 backward extension of the marginal portion of the median band, unac- 

 companied as it is by any tendency to forward expansion, is a striking 

 character, though not in itself of any great taxonomic value. 



SCYMNUS, Kug. 



6*. vtrginalis, n. sp. — Form broadly oval, convex, outline of thorax 

 and elytra nearly continuous. Beneath testaceous, the femora more or 

 less piceous, above black, anterior angles of the prothorax indefinitely 

 paler, each elytron with a large oval spot (most of which is antemedian), 

 and a triangular lateral mark, broadest on the base and gradually narrow- 

 ing posteriorly, orange-red. Head extremely sparsely and minutely 

 punctured. Prothorax sparsely and finely punctured, narrower at apex, 

 broadest in front of the middle, sides arcuate anteriorly, more nearly 

 straigiit behind, basal margin not regularly curved, but sub-sinuate laterally 

 and truncate in front of the scutellum, the marginal line visible, but not 

 well marked. Scutellum finely punctured. Elytra more deeply and 

 coarsely punctured than the prothorax, the surface (when denuded of 

 pubescence), shining. Prosternum with the elevated ridges subparallel. 

 Mesosternum punctate and rugulose, metasternum more coarsely punc- 

 tured at sides. Abdomen not closely nor coarsely punctured, the meta- 

 coxal arc covering only about half the width of the first abdominal segment 

 and not attaining the outer anterior segmental angle. Length, 2.85 mm., 

 .114 inch. 



Found at Leeds, St. George and Chadburn's Ranch, all in the Virgin 

 Riv^er basin, of southern Utah. I took a number of specimens of this 

 fine large species, in July, and they show considerable variation in color- 

 ation. The pattern described above is that of the type, and seems to be 

 the most characteristic ; some individuals, however, have the reddish 

 elytral spot confluent anteriorly with the latero-basal mark, so that only 

 the sutural region and a large apical blotch remain black. The head, in 

 one specimen, becomes reddish, and in this individual there is also a 

 narrow transverse reddish stripe on the prothorax. The extent of the 

 prothoracic pale margin is somewhat variable, and the abdomen is occa- 

 sionally clouded along the middle. The pubescence, above and beneath, 

 is whitish, not concealing the surface colour. By Dr. Horn's synopsis, 

 this species belongs next to cinctus, l^QC, zwd it seems certainly different 

 from any of those described later by Major Casey.
