114 GEO. H. HORN, M. D. 



used, later in the " Check List " Crotch places the species as synonym of 

 rufipennis Chev., but without making greater allowances than I think 

 possible the description of Chevrolat will not fit our species. For these 

 reasons I have given a new name to the species hoping that in the future 

 a proper apportionment of the species of the composite genus Cantharis 

 among several of its valid subdivisions will enable our species to resume 

 the name proposed by LeConte. 



P. insiilata Lee. — Head almost entirely black with a frontal yellow space 

 enclosing two small black spots. Thorax with a large discal black space which is 

 sometimes divided, three lateral spots and one at each hind angle. Elytra dark 

 brown or piceous, entire limb narrowly yellow, a short oblique yellow vitta begin- 

 ning at the humerus and a subapical spot often joining the suture. Legs entirely 

 black. Length .75 inch; 19 mm. 



The elytral markings (PI. 5, fig. 17) are very constant and show but 

 little variation. 



Occurs in Texas. 



P. Gerinuri Hald. — Beneath black. Head black with large frontal space 

 yellow. Thorax reddish yellow, with two round discal black spots. Elytra densely 

 punctured, subopaque, yellowish, a sutural vitta broader posteriorly, extending 

 nearly to base, piceous. Legs piceous, basal half of femora and tibiae yellow. 

 Length .40 inch; 10 mm. 



The elytra are marked as shown on PI. 5. fig. -\ , and exhibit no vari- 

 ation. 



Occurs from ^laryland to North Carolina but seems to be rare. 



P. (IiMCOidoa. Lee— Black beneath, last ventral segment yellow. Head yel- 

 low, very sparsely finely punctured. Thorax yellow with two small discal black 

 spots, surface shining with very sparsely placed punctures, feebly shining, an oval 

 piceous scutellar spot, suture piceous, broader at middle, an oblique somewhat 

 sinuous vitta extending from the suture nearly to the apex. Legs yellow; knees, 

 tips of tibise and tarsi piceous. Length .22-.44 inch; 5.5-11 mm. 



The only variation observed in this species is in the color of the legs 

 which may become almost entirely piceous. The elytral ntarkings which 

 are very constant are shown on PI. o, fig. 20. 



Occurs in Texas. 



P. in vita n. sp. — Beneath black. Head black, an oval frontal space yellow, 

 surface coarsely, deeply and rather closely punctured. Thorax yellow, a large 

 discal black spot sometimes divided, surface irregular with numerous coarse and 

 deep punctures near the base and sides. Scutellum black. Elytra subopaque, 

 densely punctate scabrous, finely pubescent, color and markings as in discoidea. 

 Legs entirely black. Length .40-.fiO inch; 10-15 mm. 



The elytral markings so closely resemble those of discoidea that I 

 have thought it unnecessary to repeat the fisrure. The only variation 

 observed is in the sutural vitta, which may be very narrow or entirely 

 absent.
