232 ME. M. JACOBY OX PHYTOPHAGOUS COLEOPTERA [Mai*. 6, 



Differing from every other species of the genus in the colour of 

 the antennae, in connection with the distinctly punctured thorax 

 and very strongly punctured elytra. 



IVONGITTS PUNCTICOLL1S, Sp. 11. 



Below black, above metallic dark greenish ; legs piceous, the 

 basal joints of the antenna? and the tibiae flavous ; head dark 

 fulvous; thorax rather stronaly punctured; elytra strongly punctate- 

 striate ; femora unarmed. 



Length 3 millim.* 



Of short, ovate, and very convex shape ; the head obscure fulvous, 

 the vertex greenish piceous at the base, the surface impunctate or 

 with a few fine punctures ; the clypeus entirely obsolete : the eyes 

 surrounded by a narrow sulcus ; antenna? flavous, the terminal four 

 joints black, second joint but slightly shorter than the third, 

 the apical joints very slightly thickened ; thorax nearly twice as 

 broad as long, not narrowed anteriorly, the sides straight, the 

 surface closely and rather strongly impressed with round punctures, 

 which leave only a small longitudinal space at the middle smooth ; 

 elytra scarcely wider at the base than the thorax, narrowed towards 

 the apex, dark greenish, strongly punctate-striate, the interstices 

 with some minute punctures, convex near the lateral margins, the 

 shoulders acutely raised and slightly obliquely costate, lateral 

 margins reflexed ; below blackish ; the legs robust, dark fulvous, the 

 femora stained with piceous ; presternum broad, transversely 

 rugose, its anterior margin elevated. 



Hah. Mozambique. 



The principal characters of Ivongius — the unarmed femora and 

 elevated anterior margin of the prosternum — are present in the 

 species described here, of which two specimens are contained in my 

 collection ; but the line of separation between the epistome and the 

 head is entirely absent, so that this character used by itself is 

 unreliable as applying to the genus, but it is used by the author 

 (v. Harold) as one of the distinguishing features of Ivongius. The 

 dark fulvous head, punctation of the thorax, and colour of the legs 

 will separate this species from any of its allies, which for the most 

 part are inhabitants of Madagascar. 



ElTRYDEMTJS MABG1NATUS, sp. n. 



Pale fulvous, the breast piceous ; thorax impunctate ; elytra 

 strongly punctate-striate, with basal depression, the extreme 

 sutural and lateral margins black. 



Length 4 millim. 



Head remotely punctured as well as the clypeus ; the latter 

 separated from the face, subquadrate, its anterior margin straight ; 

 eyes rather large, distinctly notched ; antenna? slender, fulvous, the 

 second joint nearly as long as the third, the following joints 

 elongate ; thorax one half broader than long, strongly narrowed 

 anteriorly, the sides oblique, scarcely rounded, the angles dentiform, 

 the surface deflexed at the sides near the anterior angles, entirely
