CERAMBYCID/E 337 



entirely pale. Length (cf ) 16.5 mm.; width 5.3 mm. Unlabeled in the 

 Levette collection. 



Very different from punctatus in the sparser pubescence of the 

 prothorax and under surface, longer and rather heavier antennae, 

 less transverse prothorax and different form of the elytral black 

 marking. The female is more heavily marked with black and with 

 the black elytral patch more angulate anteriorly than the male in 

 this part of the genus, though apparently not so in the pulchellus or 

 discoideus sections. 



The following species is allied to testaceus Lee., differing in its 

 much finer sculpture: 



Crossidius maculicollis n. sp. Oblong-elongate, moderately convex, 

 scarcely shining and densely clothed with short stiff flavescent hairs, 

 more erect, longer and bristling anteriorly, pale testaceous in color, the 

 head black, the pronotum with four large blackish cloud-like spots in- 

 volving the convexities, the elytra wholly immaculate; under surface 

 infuscate and with longer dense coarse pubescence; antennae (cf) 

 blackish, piceous distally, slender, about as long as the body, or ( 9 ) 

 much stouter, blacker and barely extending behind the middle of the 

 body; prothorax coarsely, densely and clearly punctate, less coarsely and 

 more irregularly in the male, the sides feebly tuberctilate behind the 

 middle, more strongly in the male; elytra slightly wider than the pro- 

 thorax and two and one-half times as long as wide, subparallel, the apices 

 evenly rounded to the obtuse sutural angles; surface with rather small 

 but very deep and dense punctures, becoming larger and separated near 

 the base, the discal thread-like lines very feeble. Length (cf, 9 ) 12.8- 

 15.0 mm., width 4.0-4.8 mm. California (Los Angeles Co.). 



Differs from testaceus, not only in the very much less coarse and 

 extremely dense elytral sculpture, but in the subobsolete discal 

 raised threads, which are very strong in the latter; it also differs 

 in its shorter and darker male antennas and in the distinctly de- 

 marcated four black thoracic spots. Testaceus is from San Diego. 



The two following species are allied to crassipes, and in the same 

 way, have the second joint of the middle tarsi distinctly wider 

 than long: 



Crossidius wickhami n. sp. Form and coloration nearly as in crassipes 

 but a little shorter; head and prothorax deep black; antennae (cf ) slightly 

 longer than the body, of the usual structure; prothorax nearly three- 

 fifths wider than long, coarsely, densely punctured and with bristling, 

 rather abundant but not dense erect pale hairs, and an acute lateral 

 tubercle well behind the middle; elytra but slightly more than twice as 

 long as wide, the black sutural area narrow, fusoid, scarcely extending 

 in front of the middle, the punctures everywhere rather fine and extremely
