594 PHYTOPHAGA. 



Head impunctate ; the frontal tubercles nearly obsolete ; antennae about two thirds the length of the body, 

 black, the second and third joints small, the latter slightly longer than the second, the fourth and following 

 joints very elongate ; thorax twice as broad as long, the lateral and the posterior margins slightly rounded, 

 the surface finely punctured, obsoletely depressed on each side ; elytra not more strongly punctured than 

 the thorax, with two spots at the base (the inner one near the scutellum, the outer one on the shoulder), 

 a spot, of more elongate shape, near the suture below the middle, the lateral margins posteriorly, and the 

 apical margins also, black ; posterior femora at the apex, and all the tibiaa and tarsi, black ; the underside 

 fulvous ; the first joint of the posterior tarsi half the length of the tibia. 



Hob. Mexico, Yolotepec, Juquila {Salle). 



10. Luperodes impressicollis. 



Black, the head, the three basal joints of the antennas, the thorax, and legs fulvous ; head and thorax finely 

 punctured, the latter impressed ; elytra dark blue, very finely punctured. 



Length 2 lines. 



Head finely and rather closely punctured at the vertex ; the frontal tubercles transverse, bounded posteriorly 

 by a deep transverse groove ; clypeus with a distinct central ridge ; antennae about half the length of the 

 body, the joints rather short and robust, the three lower joints fulvous, the others black, the third joint 

 very little longer than the second ; thorax twice as broad as long, the sides slightly rounded at the middle, 

 the posterior margin somewhat sinuate, the disc finely and closely punctured, with two more or less deep 

 depressions which sometimes nearly unite ; scutellum black ; elytra very closely and finely punctured, 

 dark metallic blue ; underside black, clothed with yellow pubescence ; legs fulvous, all the tibise armed 

 with a spine ; the first joint of the posterior tarsi rather longer than the following joints together ; claws 

 appendiculate ; the anterior coxal cavities open. 



Hab. Mexico, San Andres Chalchicoinula, Jacale (Salle), Oaxaca (Hoge). 



11. Luperodes minutus. 



Testaceous, the sixth and seventh and the apical three joints of the antennae, black ; thorax finely punctured, 

 with the sides black ; elytra closely punctured, an oblique longitudinal streak from the middle of the base 

 to the suture, a transverse band below the middle, and the sides, piceous. 



Var. The elytral markings nearly obsolete. 



Length 1 line. 



Head impunctate ; antennae as long as the body, the second and third joints very small, equal ; thorax twice as 

 broad as long, finely punctured, with a more or less distinct lateral depression, the lateral margins black 

 or piceous ; elytra very finely and rather closely punctured, very obsoletely depressed below the base, 

 testaceous, with a short piceous streak commencing at the middle of the base, this streak being connected 

 with an oblique and pointed stripe extending from the base to the suture (forming a V-shaped mark with 

 the corresponding stripe on the other elytron), and a broader and irregular transverse piceous band below 

 the middle, the latter connected with the similarly-coloured sides ; the underside and legs testaceous ; the 

 first joint of the posterior tarsi half the length of the tibia. 



Hob. Panama, Bugaba, David (Champion). 



This is the smallest of our species. In the elytral markings L. minutus resembles 

 L. biannularis and L. apicicornis, but differs in the colour of the antennae ; the V-shaped 

 anterior markings of the elytra are directed obliquely downwards along the suture, and 

 the posterior band does not occupy the apices : these differences, together with the 

 small size, will help to distinguish L. minutus from its allies.
