1 (a). Cryptognatha annulata. 



Corpus cum pedibua luteum, capitis basi prothoraceque nigris, hoc angulis anticis, illo fronte luteis ; elytris 

 sanguineis, annulo submarginali lato nigro, margine apicali ipso sanguineo ; capite subtiliter, protborace 

 elytrisque crebre distincte ac minute, punctatis. Long. 2'75 millim. 



Mas ? capite (basi excepta) luteo. 



Hah. Panama, Volcan de Chiriqui (Champion). 



Orbiculate, and nearly hemispherical, very shining; the body beneath, the head 

 (excepting at the base), the deflexed angles of the thorax, and the legs yellow. The 

 tibise are obliquely cut off for the reception of the tarsi, and are not toothed or angular, 

 and scarcely project at the angle formed by the truncation externally. The mouth is 

 yellow, the trophi very short (not observed). The thorax is very distinctly and thickly 

 punctured, black, with a brassy tint, its base with a fine marginal line ; the angles in 

 one example very narrowly blood-red, in the other (perhaps the male) widely luteous. 

 In this last-mentioned example the head is luteous, and the base has the black part 

 as a double spot, whereas in the other example (the possible female) it is blood-red, 

 with the basal half black. The elytra are convex, distinctly punctured ; the disc is of 

 a fine deep chestnut or blood-red, this colour reaching the base ; from the basal angles 

 runs a broad black band along the margin, but leaving it at halfway, the two bands joined 

 at the suture, and leaving the apical margin red. There is in the female (?) example 

 a row of subcutaneous fuscous-black dots parallel to the suture, but the true punc- 

 tuation is nowhere serial ; it is also very evenly distributed, being a little closer near 

 the apex of the elytra. 



Two examples. 



l (b). Cryptognatha amicta. 



Corpus cum pedibus caputque (protboracis margine antico et lateribus late concoloribus) albido-flava ; 

 elytris sanguineis, annulo lato marginali per prothoracis basin provecto nigro, margine apicali tenuiter 

 sanguineo. 3 . Long. 2-75 millim. 



Hab. Panama, Bugaba (Champion). 



Very similar to C. annulata, but more widely orbiculate ; the thorax wider and its 

 sides more uniformly in outline with the elytra, forming an almost perfect circle. 

 The punctuation (especially that of the thorax) is much finer. The head is whitish- 

 yellow, hollowed out in front, wide, the outer angles of the clypeus turning outwards. 

 The thorax has the front margin and sides widely whitish, the black portion of 

 the base not reaching nearer than a quarter of its width from the hind angles, and 

 therefore, though completing the black ring, not being as wide nor quite continuous 

 with it. The scutellum is red, whereas in C. annulata it is black. The front tibiae 

 are outwardly widened and compressed, especially near their base. 



Two specimens, both males.
