Coleopterological Notices, IV. OGt 



Prosternum more or less deeply and narrowly impressed or sulcate, 

 the coxiB laroi'e, prominent and narrowly separated. The niet- 

 episternum varies in width according to the species, and the abdo- 

 men is conv^ex, becoming strongly ascending toward apex, where it 

 is generally retracted slightly above the plane of the sutural angles 

 of the elytra. The scutellum is small, glabrous or nearly so and 

 the body is always unevenly and more or less densely squamose. 



The species are moderately numerous ; those known to me may 

 be identified as follows: — 



Body glabrous above, with two wide, abruptly limited vittre of large pale 

 densely placed scales, the outline evenly elongate-oval. ...1 'biTitta.tllS 

 Body elongate-oval, unevenly squamose above, the scales forming shorter or 

 longer lines on the elytral intervals or, when the latter are densely 

 squamose throughout, with the intervals two, four and six in greater or 

 less part paler, especially toward base. 

 Elytra not densely squamose throughout. 



Elytral punctures line, the sixth interval with a broad dense line of scales, 

 abruptly terminating at basal fourth ; white scales of the second inter- 

 val not extending beyond apical fifth 2 cribricollis 



Elytral punctures coarse and dense, the sixth interval with the line of 

 large white scal,es extending fully to the middle and thence nearly to 

 apex, but with narrower, sparser and darker scales; second interval 

 broadly clothed with large white scales from base to apex. 



3 sqiianioliiieatiis 



Elytra densely squamose throughout, the scales ochreous-brown in color, 



but white on the alternate intervals through portions of their extent 



and more especially toward base. 



Prothorax with the scales of the under surface large and dense throughout 



toward the sides ; pronotal punctures rather finer and moderately close. 



4 suffusus 



Prothorax with a large quasi-denuded area involving the lateral jwrtions 



of the under surface toward base, on which the scales become very fine 



and sparse; pronotal punctures coarse and denser 5 difiicilis 



Body unevenly squamose above, the scales of the elytra not at all lineate in 

 arrangement, but more or less denuded, especially on the flanks and often 

 also at the posterior callus. 

 Body more broadly oval. 



Vestiture dense, the anterior coxse separated by about one-fourth of their 



own width G liitescens 



Vestiture sparse, the scales narrower; anterior coxse separated b}^ nearly 



one-half of their own width 7 curticollis 



Body narrow and linear, almost as in the second division of Barileptou. 



Vestiture of the pronotum broadly and abruptly dense toward the sides, 



the median glabrous area occupying but slightly more than one-third 



of the total width 8 albescens
