tractus ; but differing from it by the thorax being rather longer, and with its sides 

 not so parallel at the base, and hence having the hind angles somewhat acute 

 instead of rectangular. The head is very finely punctured, the thorax more deeply 

 and distinctly so, evenly over the whole surface. The antennae are short; the five 

 terminal joints and the tip of the sixth joint jet-black. The elytra have a very sparse 

 golden pubescence, which (as in A. contractus) probably soon wears off ; their disc is 

 black, but the apical third, however, is of the deep red colour of the body, and the 

 basal and side-margins and humeral callus and scutellum are also red. 



6. Anidrytus ? 



Hab. Guatemala, San Joaquin in Vera Paz {Champion). 



A single male example of an Anidrytus which I cannot at present determine. It is 

 apparently near A. plagiatus, Gerst., and is rufous in colour ; the last six joints of the 

 antennae are black ; and the elytra have the disc of each infuscate, but with the suture 

 and margins red. In size it is rather larger than the specimen from North Yucatan 

 which I refer to A. nitidularius, measuring eight millimetres. 



Section B. Body subparallel, and not convex. 



7. Anidrytus humilis. 



Anidrytus humilis, Gorham, Endom. Recit. p. 48 1 ; Proc. Zool. Soc. 1886, p. 160 2 . 

 Eab. Nicaragua, Chontales (Belt 2 , Janson 1 ). 



The male of this species has, in addition to the character mentioned in the original 

 description, the hind tibiae sinuate and slightly bent inwards at their apices, in the 

 same manner as they are in the following species. 



Two specimens, a male and a female. 



8. Anidrytus depressus. 



Oblongus, subparallelus, depressus, nitidus; prothorace crebre, elytris subrugose creberrime punctatis; ferrugi- 

 neus, prothoracis disco, elytris macula basali plagiaque discoidali indeterminate nigro-piceis, antennis 

 articulis sex ultimis nigris. Long. 7| millim. S • 



Mas tibiis anticis dente acuto interne armatis, tibiis posticis sinuatis ad apicem incurvatis. 



Eab. Guatemala, El Tumbador (Champion). 



Head rusty-red, with a faint double impression between the eyes, sparingly and finely 

 punctured. Antennae with five joints pale rusty-red, the succeeding ones black, all 

 rather pubescent. Thorax transverse, the disc sparingly, the hind angles more thickly 

 and strongly punctured ; the sides parallel at the base (in A. humilis they are a little 

 contracted towards the front) ; the front angles widely, the margins very narrowly red, 

 the disc pitchy. Elytra very thickly and confluently punctate, the punctures joining 

 in irregular transverse rows, and being coarser and thicker towards the base and suture ;
