424 TRANSACTIONS OF THE 



single tooth and eight submarginal punctures producing hairs ; 

 mandibles white at the base, within dark green, tip black : palpi 

 white, terminal joints green. Trunk, thorax with the submarginal 

 liaes blue, quadrate, not straitened behind; elytra obscure, punc- 

 tured irregularly with green, punctures larger than in [412] the 

 preceding species, more conspicuously serrate at the hind margin 

 and mucronate at the inner tip : anterior lunule originating on the 

 humerus, continued a short distance on the margin, and curved 

 rather towards the base of the elytron, intermediate band divari- 

 cated on the margin, so as to attain the lunules, but is sometimes 

 interrupted before the posterior, refracted in a somewhat acute 

 angle at the centre of the elytron, thence recurved nearly parallel 

 with the suture, and dilated at its termination ; posterior lunule 

 terminal ; feet red-cupreous, hairy ; trochanters purple. Abdo- 

 men, venter blue, segments tipped with brassy ; tail purple. 



This insect does not appear to have been described except in 

 the work to which the synonym refers ; it had been previously 

 overlooked, probably in consequence of its proximity in point of 

 colors and marking to the preceding species, which it generally 

 accompanies ; but a small degree of scrutiny will detect a suffi- 

 cient number of discriminative characters to warrant us in con- 

 stituting of this insect a distinct species; in size its female is 

 equal to the male of 0. vulgaris, the punctures of the elytra are 

 much larger, the intermediate band is so widely spread out upon 

 the margin, as nearly to connect the anterior and posterior 

 lunules, and the tip of the anterior lunule is curved towards the 

 base of the elytra, and not obliquely towards the tip, as in the 

 preceding species ; a striking difference also is perceptible in the 

 upper lip which in that insect is three-toothed, but in the O. hir- 

 ticoUU it is one-toothed. Neither this nor the preceding species 

 have been observed to vary in their colors or markings. 



[Ante, 2 ; this description and figure evidently refer to the 

 species afterwards described as C. alhohirta Dej. The figure is 

 quite characteristic, and can by no means be regarded as C. hal- 

 timorensis Herbst., {_repanda Dej.) — Lec] 



3. C. UNIPUNCTATA. — Dull cupreous, obscure, naked, base of 

 the mandibles, labrum and marginal dot on each elytron, white.
