26 B. C. ENTOMOLOGICAL SOCIETY 



brighter beneath, coarsely, deeply and unevenly punctate with dark green. Head 

 sub-quadrate, longer than wide, margined with dark green, often with two dark, 

 short stripes on the basal raised lines, and with a dark streak on the middle of 

 the tylus, reliefs between the eyes strongly defined, lateral lobes somewhat longer 

 than the tylus. more finely punctate than the vertex, their outer angles a little 

 rounded and marked with dark green. Underside of head polished, sparsely and 

 finely punctate in separated patches or lines, the under submargin of the lateral 

 lobes closely and deeply punctate;, rostrum reaching to just behind the middle 

 coxae, the second joint reaching to the posterior margin of the anterior coxae; 

 antennae dusky rufous, darker on middle of last three segments. Pronotum wide, 

 deeply, coarsely punctate, mostly in transverse wavy lines, and punctures partly 

 confluent on the disk, depression at base of forward lobe marked with a trans- 

 verse series of indented and discolored spots, the posterior lobe more or less 

 darkened with obscure green, the humeral angles irregularly triangular, callous 

 at tip, a little shorter and less acute than in P. cynicus Say., the extremity often 

 dark green, and charged with four wrinkles, anterior part of lateral margin 

 coarsely granulate-serrate. Pleural pieces coarsely, remotely, deeply punctate, 

 excepting the area around the ostiolar canal. Legs luteous, sparsely punctate, 

 tlie femora more or less pointed with rufous, and wrinkled. Scutellum more 

 finely punctate, clouded with green, the middle line smooth and very sparsely 

 punctate. Clavus narrow, dark, luteous, greenish at base, punctate in lines; 

 corium finely and remotely punctate with green, the costal area more coarsely 

 so, and more spotted, membrane longer than the venter, pale bronze, finely 

 granulated, the veins a little darker. Venter coarsely, remotely, unevenly 

 punctate and rugose on the sides, with a broad, smooth, middle line, almost 

 impunctate; tergum purplish black, dull, the connexivum orange, punctate with 

 red, the sutures of the segments broadly marked with a quadrate, black-green, 

 densely punctate spot across the entire width of the connexivum; ventral spur 

 long, acute in the male, blunter in the female. Length to end of venter 13 to 

 17 mm. Width across humeral angles 8 to 10 mm. 



"This species is common in Western Oregon and Washington Territories. 

 It occurs also on Vancouver Island, and extends south into California. The third 

 joint of the antennae is much shorter than the preceding or following ones, the 

 second is longest, and nearly twice as long as the third. The species is very 

 variable in the degree and amount of dark marking on the several parts of the 

 upper surface." 



The color of both sexes varies considerablj', but in general the 

 ground color is pale brown or fawn, inore or less suffused or mottled 

 with dark green with a metallic lustre. In some individuals the ground 

 color is almost obscured, while others are uniformly pale with an entire 

 absence of green exceptitig the brilliant metallic spots on the connex- 

 ivum. In such individuals the tergum is crimson ; in dark specimens 

 it is black. 



'The vaginal plate is triangular, and the characteristics of the female 

 genitalia resemble those of its near ally bracteatus. The most notice- 

 able structural character differentiating crocatus from bracteatus is the 

 shape of the lateral pronotal spines, which are short and blunt, while 

 those of bracteatus are decidedly more acute and projecting. In a 

 series of eighteen specimens of crocatus before me I find this feature 

 constant. In cynicus the vaginal plate is quadrangular, which clearly 

 distinguishes it from both crocatus and bracteatus.
