Length o-bh millim. 



Mas. Eather elongate, sliglitly narrowed posteriorly, the head 

 strongly bnt remotely jaunctnred, with a shallow central longitudinal 

 groove, epistome wedge-shaped, strongly punctured, its anterior 

 margin nearly straight, antennae extending to the middle of the 

 elytra, black, the lower five joints fulvous, the third and the follow- 

 ing three joints elongate, nearly equal ; thorax about one-half 

 broader than long, very strongly narrowed in front, tlie sides rounded 

 with a narrow reflexed metallic greenish margin, the surface convex, 

 extremely finely and closely punctured throughout, the posterior 

 margin with tlie median lobe moderately produced ; seutellum 

 impunctate, bluish ; elytra with a distinct depression below the 

 base, punctured like the thorax, the punctures placed in distant

 the tibia3 bluish, the posterior femora rather strongly developed. 



JI(d). Amazons. 



I know of no other species of Aglalus of similar 

 coloration and with such fine punctuation ; the male has 

 the characteristic long calcar near the apex of the posterior 

 tibiae, which are furnished at the same phice with long 

 fulvous pubescence ; the specimens which I look upon 

 as representing the females of the same species, are shorter 

 and broader, the thorax is more transverse and mucli 

 less narrowed in front, and the elytra are more strongly 

 punctured, the antennas are also shorter, and the tibial 

 spur is absent, the colour and the punctuation of the 

 thorax are similar to those of the male. 



Aghalus hoHvianus, sp. n. 



Below a3neous, above metallic greenish, basal joints of the antenna3 

 and the legs fulvous, thorax very closely punctate, elytra strongly 

 and closely semi-punctate-striate, tarsi blackish. 



Length 4 millim. 



Of elongate, parallel shape, the head remotely and strongly 

 punctured, with a deep, central, longitudinal groove, the clypeus 

 punctured like the head, antenna) long and robust, black, the lower 

 four joints fulvous, third and fourth joints equal, terminal joints 

 distinctly thickened ; thorax twice as broad as long, of nearly equal 

 width, scarcely narrowed in front, the sides rounded, with a narrow 

 reflexed margin, the surface closely and rather strongly punctured, 

 with numerous smaller punctures intermixed; seutellum broad, 

 impunctate ; elytra with a distinct sub-basal depression, more
