AGEYPNELLA. 415 



are common to the Agrypnini and others to the Cryptohypnini ; but the genus cannot 

 be included in either of these groups as at present defined. It differs from the 

 Agrypnini in the prominent frontal plate and feeble antennal grooves, and from the 

 Cryptohypnini in the very much narrower presternum and the carinated and shallowly 

 grooved propleurse. The propleural carina is distant from the margin throughout : in 

 some genera of the group Cardiophorini the carina incompletely separating the pro- 

 pleurse from the pronotum is also placed beneath, but in this case it extends inwards 

 from the hind angles *. The hind angles of the thorax are formed very much as in 

 various species of Lacon and Meristhus, near which the genus should probably be 

 placed. A. squamifera lives under stones on the sandy banks of rivers.

 Panama, Tole (Champion). — South America, Venezuela 2 , Cayenne 34 , Santarem, Ega,

One specimen only has been found at each of the three Central- American localities 

 quoted. Numerous South-American examples are contained in the Janson collection, 

 including Candeze's type from Para and two from Cayenne from the Dejean collection. 

 The scales in fresh specimens completely hide the sculpture. Our figure is taken from 

 the Guatemalan example. 



Group CARDIOPHORINI. 



To the chief characters given for this group, viz. the heart-shaped scutellum, and the 

 short, wedge-shaped, truncated prosternal process, it may be noted that the anterior 

 coxal cavities are partly or almost entirely closed behind by the prothoracic epimera, 

 instead of being widely open as in the Cryptohypnini. The prosternal process has a 

 brush of long hairs at the inner apical angle. 



beyond the middle, and a small dot midway between this and the apex, fuscous, the three inner inter- 

 stices of the elytra each with a line of ochraceous scales down the centre, the fourth, fifth, and sixth 

 interstices also with a line of similarly coloured scales at the base ; beneath paler than above, the legs 

 and antennas testaceous. Head and prothorax thickly punctured ; the prothorax broader than long, 

 rounded at the sides, widest at the middle, the hind angles obliquely truncate. Elytra oval, broader than 

 the prothorax ; punctate-striate, the outer interstices convex. 



Length 3^, breadth 1| millim. 



Hob. Amazons, Santarem (Bates, in coll. Janson). One specimen. 



* In Cardiophorus mirabilis, Cand., from India, which should probably form the type of a new genus, the 

 carina is complete and distant from the margin throughout.
