1907.] SPECIES OF CRYPTOCEPHALIXE BEETLES. 839 



Somewhat allied in coloration to C. 4:-vittatus Jac. from 

 Central America, but distinguished from that and .some other 

 species by the j^ropoitionately long thorax and its two black 

 bands. 



Cryptocephalus flohri, sjd. n. 



Above yellowLsh white ; the head with two, the thorax with four 

 longitu<linal brown bands ; elytra strongly punctate-striate, the 

 alternate interstices pale brownish. 



Length 3g millim. 



Head nearly white, with a central brown stripe which divides 

 anteriorly into two branches, this portion distinctly punctured, 

 rest impunctate ; eyes very bi'oadly but not deeply notched ; 

 clypeus transverse, deeply triangularly emarginate, the base with 

 a narrow transverse brown stripe ; antennae extending just below 

 the base of the elytra, black, the lower four joints fulvous, third 

 and fourth equal, each shorter than the fifth joint. Thorax twice 

 as broad as long, the lateral margins nearly straight, anterior one 

 about half the width of the posterior ; suiface sparingly and 

 extremely finely punctured, coloured like the head, with four 

 .slightly curved ferr-uginous bands from base to aj)ex, of nearly 

 equal width and distance, the two middle ones nearly touching 

 at the base and not quite extending to the anterior mf>rgin, the 

 lateral bands with a very narrow short stripe at middle branching 

 off at right angles outwai-ds. Hcutellum yellow, margined with 

 black. Elytra narrow and parallel, strongly and regularly punc- 

 tate-striate, the seventh row interrupted below the shoulders and 

 closely approached to the eighth row, second row united with the 

 ninth at the apex ; the interior of all the punctures dark browai ; 

 the third, fifth, and seventh interstices pale fulvous ; humeral 

 callus likewise dark brown, extreme sutural margins nearly black. 

 Breast and abdomen dai'k brown, strongly rugose-punctate ; femora 

 and tibife likewise brown ; a spot at the apex of the femora, 

 anterior coxfe, upper portion of the breast, a subquadrate spot at 

 the metasternum, and the pygidium yellowLsh white, the latter 

 strongly punctured. 



Hah. Guanajuato, Mexico. 



A very prettily marked species, of which I received a specimen 

 from the late Mi-. Flohi', too late for description in the ' Biologia 

 Centr. -Americana.' 



Cryptocephalus apicipes, sp. n. 



Pale fulvous ; the antennfe, apex of the tibise, and the tarsi 

 black ; thoi-ax with a deep semicircular groove at the po.sterior 

 angles, impunctate ; elyti'a finely punctate-striate. 



Length 4 millim. 



Head slightly rugose or uneven ; the large eyes deeply sub- 

 quadrately emarginate, the emargination placed at the middle ; 

 clypeus wedge-shaped, broad, impunctate ; antennfe black, the
