 hairs. Maxillary palpi black, last three joints subequal (the 

 penultimate slightly shorter), apex of terminal joint very obliquely 

 truncate. Mandibles strong, upper side nearly flat. Under side 

 of head sparsely pubescent, the hairs arising from moderately fine, 

 strigose punctures; gular suture very strong anteriorly, fossa 

 elongate, very narrow, nearly closed. Pronotum half as long as 

 wide, as wide as body at humeri; disc sm^ooth, shining, very 

 minutely punctulate, with small impression before scutellum; sides 

 broadly explanate, the dilated margins each about one-eighth of 

 the entire width, base almost straight, feebly trisinuate; hind 

 angles rounded; side margins straight, very slightly convergent 

 anteriorly; front angles obtuse, broadly rounded; front margin 

 strongly arcuate at middle, nearly straight on each side. Elytra

 surface shining, scabrose, punctulate, with fine dark brown 

 pubescence, apices attenuate strongly divergent. Wings creamy 

 white, costa and media brown, other veins pale, a cross- vein be- 

 tween the forks of the cubitus. Abdomen pale, except large black 

 spot on dorsum of last three segments. Legs pale, except tarsi, 

 which are black with dark pubescence, fourth tarsal joint with an

Type in the Carnegie Museum. Paratype, No» 16332, U. S. 

 National Museum. 



Two specimens collected in June or early July, 1904, by the 

 late Dr. W. Miller, in San Bernardino Co., Cal. (exact locality 

 unknown), and kindly loaned to the writer by Mr. H. G. Klages, 

 who has generously placed the paratype in the U.S. National 

 Collection. This is certainly the handsomest species of the genus 

 knov/n in our fauna. It is distinguished from any other species 

 in the United States by the black elytra and whitish wings. A 

 variety (?) of P. bipennifera Gorh. is figured in the Biologia Cen- 

 trali-Am.ericana as having black elytra but specimens have not 

 been seen by the writer. •
