sternum rertical in front, profoundly and clearly excavated into form of V ; pro- 

 sternal process prominent, lanciform, longitudinally convex, not margined, iinely 

 punctured ; intercoxal process naiTOTv, tapering, the apex pointed ; first joint of 

 posterior tarsi longer than the last. Long. corp. 4j lin. 



Hab. : Venezuela ; one examj^le. 



AlEGOEIA PAEALLELA, sp. 11. 



Smaller, naiTower, much less depressed, and less glossy than the preceding ; 

 antcnnse, palpi and tarsi clear red, legs and labrum chestnut-red ; the mentum is 

 less transverse than in the preceding species, the middle of the fore margin is 

 notched, the fore angles are strongly rounded, and the sides more narrowed to the 

 base, the punctuation is coarser and sparser, and it is not furrovred (or sulcate) 

 down the median line ; the last joint of the maxillary palpi is of the same form as 

 in the preceding, i. e., elongate, ovoid, and truncate at tip ; the labrum is broadly, 

 and almost squarely, truncated in front ; the epistoma and antennary orbits are of 

 the same form as in the preceding ; the outer (terminal) five joints of the antennro 

 are of the same form as in A. quadraticollis, but joint 6 is much larger and wider,* 

 joint 3 longer and somewhat obconic, and joint 2 smaller and cylindrical ; the ele- 

 vated ridge between the eyes (on the crovm) is miich less marked than in the pre- 

 ceding species, consequently the depression on the front is faint or almost obsolete, 

 that at each side the epistoma is equally strongly marked ; the neck is much less 

 coarsely rugose-punctate ; the prothorax in the present species is a little squarer, 

 consequent on the sides anteriorly being somewhat less contracted, the emargination 

 in front is shallow and less sinuous, and the antei'ior angles less prominent and more 

 depressed, the base is equally strongly sinuous, and has the three impressions as in 

 the preceding ; the punctuation — especially at the sides — is sparser ; the elytra are 

 more parallel (i. e., not, or scarcely perceptibly, expanded behind the middle), some- 

 what convex (the lateral margins not being visible when the insect is looked at 

 from above), the punctures in the strise are less rounded and regular ; the legs, pro- 

 and mesosternum, and intercoxal process are all formed as in the preceding species. 



Long. Corp. 3f lin. 

 Sah. : Brazils ; one example. 



It is possible this may be the " second species " mentioned by 

 Lacordaire (Cxen. Col., v, p. 326), and it is more than probable that it 

 will eventually be linked to the preceding as but an extreme variety. 



Corrections. — In No. 2, p. 133, in my description of Epiphysa ovata, 

 &c., I have written o£ the prosternum it has " the apical two- 

 thirds," &c., it should be the posterior two-thirds, &c. On 

 page 134, I have written the prosternal groove anteriorly is 

 quite smooth, &c., it should be the prosternal groove pos- 

 teriorly is quite smooth, <fec. I shall always describe as the 

 hind or posterior portion of the prosternum and prosternal 

 process that portion nearest to, and facing, the mesosternum. 



* The present species may be said to have a gradually widening club of six joints, and 

 quadraticollis one of five jointtj. — F. B.
