of JEngyaulus (Tab. IV. fig. 9). Its affinity with Agceocera was not noticed until too 

 late for insertion in the proper place. 



1. Mixochlorus suturalis. (Tab. IX. fig. 12.) 



Mixochlorus suturalis, Waterh. Trans. Ent. Soc. Lond. 1887, p. 178 \ 

 Hab. Honduras j (Brit. Mus.). 



The type of this species measures 6 lines in length. It is of a bright green colour, 

 having the top of the head, a stripe on each side of the disc of the thorax, and a broad 

 stripe on the elytra dark coppery. The thorax has a well-marked longitudinal median 

 impression, which is green, a little narrowed at the anterior part, and near each side 

 there is an elongate impression extending from the base to within one-third of the 

 anterior margin ; the lateral impression is shining and very strongly and distinctly 

 punctured. The presternum is strongly punctured ; the punctures are rather near 

 together, but are not crowded. The terminal segment of the abdomen is semicircularly 

 emarginate at the apex. 



2. Mixochlorus lateralis. 



Viridis, supra subsurdus ; capitis vertice, thoracis disco (macula basali excepta) elytrorumque vitta lata 



brunneo-cupreis. 

 Long. 4| lin. 



Hab. Mexico, Orizaba (Salle). 



The front of the head is moderately finely punctured as compared with M. suturalis ; 

 the punctures near together, but not crowded. The thorax is lightly transversely 

 impressed at the anterior margin ; the disc is slightly raised anteriorly, the coppery 

 colour extending over the anterior half of the median impression, which is not so 

 distinct as in M . suturalis, and is more sparingly punctured posteriorly; the lateral 

 impression is sparingly punctured, more ovate, and does not extend much beyond 

 the middle of the length. The elytra have the sutural stripe bluish-green, the suture 

 itself being purple ; the narrow margin is dark blue, with a little green at the shoulder. 

 The prosternum is very coarsely punctured, and the punctures are crowded. The 

 terminal segment of the abdomen is truncate at the apex, or appears slightly emar- 

 ginate when viewed in some positions. 



It is not impossible that M. lateralis and M. suturalis may be sexes of one species, 

 but in the absence of any evidence that this is so I prefer at present to consider them 

 distinct.

Agaeocera gigas (p. 4). 



To the Mexican localities given, add : — Ventanas in Durango (Edge, Forrer), 

 R. Papagaio in Guerrero 1200 feet (II. II. Smith). 



The two examples from E. Papagaio have the suture of the elytra bright coppery-red.
