Tliis and the following species differ from those which precede, in so many characters, 

 that the establishment of a, distinct "-onus seems almost necessary. They are both broadly 

 oval and convex, rather coarsely punctured ; antennae longer than the head and thorax, 

 slender and with the outer joints not transverse, meso- and metastemum short, and the 

 elytra with the first stria parallel with the suture and no seutellar stria. 



1\ globosa is entirely testaceous, with two black marks on each elytron, the front 

 being zigzag, the hinder irregularly triangular. 



Length .12-14 inch. 



From the sea coast in the neighborhood of San Francisco. 



P. humerali s , n. sp. 



Similar in form to the preceding, hut less convex. The color is black, somewhat 

 bronzed, with a. red humeral spot on each elytron. 



Length .15 inch. 



California (locality unknown). 



P. p i o I. a, Mann., Bull. Moac. 1848, 377. Sitkha; is unknown to me in nature. 



TRACHYSCELIS, Latr. 



Traohysoelis, Latr., Gen. Crust, et Ins. IV, p. 879. 



The form of antenna, at once distinguishes Trachyscelis from Phaleria, and the trun- 

 cate epistoma from Ansemia. In form the species resemble .Fgialia. 



T. flavipes, Mels., E'roo. Ac.;ul. HI, v . 61. 



The upper surface is black and shining, the elytra rather deeply striate and without 

 seutellar stria, The under surface is paler and the legs yellowish. 



Length .12-14 inch. 



From the southwestern Atlantic; sea coast. 



ANEMIA, Cast. 



Ansemia, Cast., Hist. Nat. Col. II, p. a\H. 



Head broad, deeply ema .rginate, sides rather broadly dilated. Eyes deeply emargi- 

 nate, superior portion small. Mcntum small, trapezoidal. Last joint of maxillary palpi 

 elongate oval. 



Antenme short, robust, gradually thicker toward the tip, outer joints very transverse, 

 last joint slightly longer than tin- preceding and rounded at tip. Thorax very transverse. 

 Elytra as broad as thorax, and with entire epipleuree. Legs short, robust, tibia- all dilated, 

 outer apical angle of all prolonged. Body winged. 



I refer to Ansemia, an insect from California possessing all the characters assigned to 

 the species of the* Eastern Continent, with also a similarity of sculpture.
