ANCHASTOMOEPHUS. 401 



the apex, the latter extending forwards along the suture to near the base, and in some specimens poste- 

 riorly to the apex, testaceous. (Fig. 4.) 



TIab. Guatemala, Cerro Zunil (Champion). Five specimens. 



Var. p. The elytra as in a, hut with the oblique fascia extending along the suture to the base and there 

 connected with the humeral patch. 



Hab. Panama, Volcan de Chiriqui (Champion). Two specimens. 



Var. y. The elytra with a rather broad oblique post-median fascia testaceous or flavo-testaceous, the suture 

 in one specimen pitchy-brown. (Pig. 5.) 



Hab. Panama, Bugaba and Boquete in Chiriqui (Champion). Two specimens. 



The type of this species is of the female sex, and, judging from the specimens before 

 me, of unusually large size. We have three examples ( <5 $ : length 3 millim.) from 

 Guatemala agreeing with it in colour, except that the sutural stripe is considerably 

 narrower. A. suturalis is described l as having the hind angles of the thorax bicarinate, 

 but I am unable to detect the slightest trace of an inner carina (except along the basal 

 margin) in the type: there is a fine, straight carina near the lateral margin extending 

 forwards fully to the middle of the thorax, this becoming very faint in some of our 

 specimens, and nothing more. The thorax is, at least in the male, feebly sinuate at 

 the side behind, so that the hind angles are slightly divaricate. The colour of the 

 antennae and under surface is variable. The length varies from 2^-5 millim. The 

 varieties are connected with the type by intermediate forms, and they cannot be 

 satisfactorily separated from A. suturalis. 



4. AnchastOHlOrpllUS quadriguttatUS. (Tab. XVIII. figg. 6 ; 6 a, underside 



of the prothorax.) 



Oblong-oval, rather convex, shining, thickly clothed with yellowish-cinereous pubescence ; black, the elytra each 

 with two large flavo-testaceous spots — one at the shoulder and the other on the disc at about one-third 

 from the apex, the latter not quite reaching the sutural or lateral margin and sometimes indistinct, — the 

 hind angles of the prothorax and the legs testaceous ; the antennae brown, with the base paler, or entirely 

 ferrugineo-testaceous. Head convex, closely, finely punctate, the frontal carina well defined, rounded ; 

 antennae about half the length of the body in the male, shorter in the female, joint 3 considerably longer 

 than 2, a little shorter and narrower than 4. Prothorax transverse, the sides rounded from the middle 

 forwards and sinuate behind ; the hind angles narrow, acute, and divergent, finely unicarinate, the 

 carina straight, close to the margin, and extending forwards to the middle of the prothorax ; the surface 

 rather sparsely, finely punctate. Elytra comparatively short, narrowing from a little below the base ; 

 finely punctate-striate, the interstices flat and sparsely punctured. Beneath thickly punctate, the pro- 

 sternum and the middle of the metasternum almost smooth ; the sutures between the prosternum 

 and propleura? widely separated, converging behind, canaliculate ; posterior coxal plates widened inwards 

 to half the width of the first ventral segment. 



Var. a. The upper surface entirely black. 



Length 2f -3§, breadth 1 millim. ( tf £ .) 



Hob. Guatemala, Cubilguitz, Lanquin, San Juan, Tamahu, and Tactic, all in Vera 

 Paz (Champion).
