Cymatodera lasvicollis, new species. 



Form, color and markings nearly as in sirpata but thorax reddish brown, shining 

 and the entire apex of elytra black. Head shining, moderately densely punctate ; 

 front with two impressions, between these the surface is convex ; eyes rather small 

 and feebly prominent ; antennae scarcely reaching beyond base of prothorax, second 

 joint slightly shorter than any of the following joints, the joints nearly equal in length, 

 but the outer slightly stouter. Thorax feebly impressed in about apical fourth, below 

 the impression moderately broadly dilated ; strongly compressed laterally in about 

 apical third, the sides then divergent to base ; disk almost impunctate, the punctures 

 evident at sides and apex ; surface very sparsely pubescent with shorter and longer 

 hairs. Elytra distinctly wider than the head, gradually but feebly divergent towards 

 apex ; apices conjointly rounded ; the rows of punctures gradually disappearing 

 towards apex, the punctures moderately coarse ; pubescence fine and rather incon- 

 spicous. Abdomen somewhat densely punctate and scarcely pubescent ; last ventral 

 as wide as the last dorsal, sides oblique, apex feebly rounded. Length 9.5 mm. 



Huachuca Mts., Arizona, one female. 



This species is best placed near sirpata from which it differs in 

 having the thorax very smooth, the eyes slightly smaller and more 

 widely separated, the antennal joints, though similar, slightly shorter 

 and narrower, the impressed front and the apex of elytra largely black. 

 The thorax is not unicolorous but slightly infuscate at sides. 



Cymatodera undulata var. arizonica, new variety. 



Form, size and sculpture of undulata from which it differs in 

 having the elytra brown with a lateral, pale median spot. Length 

 10 mm. 



Huachuca Mts., Arizona. 



I have given this form a name on account of its close resemblance 

 in form and coloration to belfragei and allies. The form is perhaps a 

 little more slender, the pubescence of thorax less dense and the 

 punctuation of head and thorax not as coarse and dense as in the 

 majority of specimens of undulata, but this is variable also in the 

 latter. The terminal abdominal and ventral segments as in undulata. 

 An entirely brown unicolorous specimen is described by Spinola as 

 bru nne a. 



Cymatodera cephalica, new species. 



Apterous, form of angustata Spin., dark brown, elytra with a more or less dis- 

 tinct pale, median fascia. Head not densely punctate ; surface more or less wrinkled 

 and rather sparsely pubescent. Prothorax elongate ; constriction at apical and basal 

 third rather feeble ; antescutellar impression distinct ; punctuation and pubescence 

 rather sparse and fine. Elytra scarcely wider at base than the thorax ; sides slightly
