Head rufo-testaceous ; antenne long, bright yellow. Thorax small, much rounded in front ; moderately punc- 
tured, with the interstices very smooth and shining; anterior margin broadly reflexed and broadly 
transparent ; basal margin much produced towards the scutellum, with the angles nearly rectangular. 
Scutellum small and rounded. lytra half as long again and broader than the thorax, widest before the 
middle, exceedingly convex ; moderately punctured, with the interstices smooth and shining ; sides margined. 
Legs moderate, bright yellow. Underparts rufo-testaceous. 
fab. Nicaragua, Chontales (Janson). 
This species is distinguished by its small size, exceedingly convex form, deep black 
colour, and bright yellow legs and antenne.

lucide albida; pronoto parvo, antice valde rotundato, minute et levissime punctato, interstitiis glabris, 
nitidissimis, margine anteriore late reflexa, albida valde translucida, margine basali modice sinuata, angulis 
fere rectis; elytris quam pronotum latioribus et plus quam sesqui-longioribus, ad media latissimis, sat 
profunde et remote punctatis, interstitiis glabris, nitidissimis, lateribus late marginatis; antennis pallide 
flavis, clava obscura; pedibus flavis, femoribus obscuratis. Long. corp. +9 lin.= 1-25 millim. 
Head pitchy-testaceous; palpi large; antenne large, pale yellow, with the club much incrassated, dusky. 
Thorax small, much rounded in front; minutely and faintly punctured, with the interstices smooth and

with the angles nearly rectangular. Scutellum rather large, triangular, impunctate. lytra wider than 
and more than half as long again as the thorax, widest at the middle ; remotely punctured, with the inter- 
stices smooth and very shining; sides broadly margined. Legs yellow, with the femora dusky. Under-

Hab. Guatemata, Zapote, Senahu (Champion). 
Differs from C. championi in its smaller size and narrower form, and in the broader 
margin and deeper sculpture of the elytra, and uniform white margin of the thorax. 
4. Corylophodes castaneus, sp. n. 
Late ovatus, postice angustatus, convexissimus, profunde et distincte punctatus, rufo-castaneus, margine 
anteriore pronoti dilutiore; pronoto parvo, antice rotundato, minutissime punctato, interstitiis glabris, 
nitidissimis, margine anteriore reflexa dilutiore, margine basali ad scutellum valde producta angulis sat 
obtusis ; elytris quam pronotum latioribus et sesqui-longioribus, ante media latissimis, postice sat attenuatis, 
validissime convexis, profunde punctatis, interstitiis nitidis, et leviter alutaceis, lateribus marginatis ; 
pedibus atque antennis pallide flavis. Long. corp. ;®; lin.=1+12 millim. 
Head flavescent; antenne pale yellow. Thorax small, rounded in front; very minutely punctured, with the 
interstices smooth and shining; anterior margin reflexed and pale; basal margin much produced towards 
the scutellum, with the angles rather obtuse. Scutellum obtusely triangular. Hlytra broader than and 
half as long again as the thorax, widest before the middle, rather attenuated posteriorly, exceedingly 
convex ; deeply punctured, with the interstices shining and faintly alutaceous ; sides margined. Legs pale 
yellow. Underparts pale testaceous. 
Hab. Guatemata, San Juan in Vera Paz (Champion).
