4. Adelocera mexicana. (Tab. XI. fig. 1.) 



Adelocera mexicana, Cand. Monogr. Elat. i. p. 70 x ; Revis. Elat. p. 31 2 . 



Hab. Mexico 12 , Tres Marias Is., Ven tanas in Durango (Forrer), Tuxtla (SallS); 

 Nicaragua, Chontales (Belt, B. M. Janson). 



I have seen nine examples of this species. It varies in colour, the elytra sometimes 

 having the suture broadly piceous to beyond the middle, and sometimes in addition a 

 postmedian fascia of the same colour. The thorax always has a large piceous patch on 

 the disc. The elytra usually have a distinct transverse postmedian fascia of brownish 

 scales. A specimen from Chontales is figured. 



5. Adelocera pollinaria. (Tab. XI. fig. 2.) 



Adelocera pollinaria, Cand. Monogr. Elat. i. p. 68, t. 1. fig. 14 l j Revis. Elat. p. 29 2 . 

 Adelocera adspersa, Cand. Revis. Elat. p. 30 s . 



Hab. Guatemala, Yzabal (Salle 3 ); Panama, Bugaba (Champion). — Amazons, Ega; 

 Brazil x 2 . 



Closely allied to A. mexicana, but differing from it in having the elytra more narrowed 

 posteriorly, and the seriate punctures coarser and less approximate. The elytra some- 

 times have nearly the apical half piceous or brown. A. adspersa, the type of which 

 we figure, differs in no way from similarly-coloured specimens of A. pollinaria from 

 Brazil. 



6. Adelocera massula. 



Adelocera massula, Cand. Elat. Nouv. iii. p. 2 \ 



*' Brevis, compacta, brunnea, opaca, sparsim pallide pilosula ; fronte antice impressa, rugosa ; antennis brevis, 

 crassiusculis ; protborace quadrato, crasso, dense et fortiter punctato ; elytris brevibus, crassis, seriatim 

 grosse punctatis, interstitiis punctulatis, tertio et quinto apice subelevatis. — Long. 8, lat. 2 millim." 



Hab. Mexico 1 . 



Unknown to me. A small species approaching A. mixta, but with the elytra 

 seriate-punctate *. 



7. Adelocera viridis. (Tab. XI. fig. 3.) 



Elongate, broad, moderately convex, black ; above and beneath somewhat sparsely and uniformly clothed with 

 closely appressed, small, bluish-green scales, which do not hide the sculpture. Head coarsely, confluently 

 punctured, concave in the middle in front ; antennae finely pubescent, nearly reaching the base of the 

 prothorax, with the joints from the third broadly flattened and serrate, 3-10 about as broad as long. 

 Prothorax transversely convex, broader than long, deeply and rather broadly sulcate down the middle ; 

 the sides arcuate and converging anteriorly, moderately sinuate behind, the marginal carina visible from 

 above, the hind angles prolonged backwards and moderately sharp ; the entire surface coarsely, confluently 



* In Candeze's Cat. Meth. Elat. (pp. 13, 14) A. massula is entered twice, under each of his sections of 

 the genus.
