APPENDIX. 







9 (a). Cratosomus interruptus, sp. n. (Tab. IX. figg. 29, 29 a, $ .) 



Oblong, shining, black, variegated above with dense, more or less confluent patches of brownish-cinereous, 

 hair-like scales, those on the prothorax nearly enclosing a very large, transverse, oval space on the disc 

 before the middle, and those on the elytra condensed into irregular spots and fasciae on the depressed 

 portions of their surface. Head closely, finely punctate, broadly sulcate between the eyes, the vertex 

 convex ; rostrum about as long as the head and prothorax, arcuate, very stout, flattened, finely punctate, 

 becoming much smoother towards the apex, carinate at the base. Prothorax transverse, rapidly, arcuately 

 narrowing from the base, densely, finely punctate, feebly carinate down the middle. Scutellum ovaJ, 

 sulcate. Elytra long, much wider than the prothorax, gradually narrowing from the somewhat prominent 

 humeri, transversely depressed at and below the base, and before and beyond the middle, the suture also 

 depressed anteriorly ; with rows of large, deep, oval fovese, which become much smaller on the depressed, 

 squamose portions of the surface, the interstices uneven, finely punctate, the third with a large, rounded 

 tubercle near the base. First ventral segment broadly excavate posteriorly. Pygidium narrowly exposed 



beneath. Femora unidentate. 

 Length ] 7, breadth 7 millim. ( $ .)

Eab. Mexico (ex Standing er). 





One specimen. Differs from all the forms of the variable C. punctulatus in the 

 seriatofoveolate elytra, which want the large flattened tubercles on the alternate 

 interstices (the third having a single large one near the base), the longer rostrum, the 

 more even prothorax, &c. Compared with the nearly allied C. cuneatus, the present 

 species may be known by the more uneven, strongly foveolate, less cuneiform elytra, 

 the larger tubercle near the base of their third interstice, and the more transverse 

 prothorax. The elytra have three narrow confluent fasciae before the middle, and 

 various irregular markings on the apical third, cinereo-squamose. 



11. Cratosomus insequalis, sp. n. (Tab. IX. figg. 30, 30 a % <$ .) 



£ . Extremely like C. bidens (antea, p. 8, t. 1. fig. 16), but differing as follows : — The vestiture of the under 

 surface (especially on the sides of the metasternum) and legs closer and coarser, flavo-cinereous, that of 

 the upper surface very sparse and fine, and not condensed into oblong patches at the bases of the elytra 

 and prothorax ; the prothorax without the two very small tubercles on the disc ; the elytra with more 

 numerous, coarse, oblong punctures in the 6trise, the scattered tubercles on the disc smaller and (except 

 towards the base) oblong in shape, the apices unarmed * ; the pygidium broadly exposed ventrally, 

 depressed, longitudinally carinate down the middle at the apex (transversely swollen towards the tip in 

 C. bidens, $ ) ; anterior femora feebly bidentate, the others each with a single rather sharp tooth and 

 the small outer one completely obsolete. 



Length 23, breadth 11 millim. 



Eab. Costa Eica (ex coll. Solari). 



A single male, extremely like C. bidens, but differing as stated above. This insect 

 was purchased from M. Donckier and it was doubtless received from the late 



P. Biolley. It is the Costa Rican representative of C. bidens, the latter inhabiting 

 Chiriqui.

* The spiniform prominence at the apex of each elytron in C. bidens was not specially mentioned in the 

 description of that species, though indicated in the figure.
