DESCEIPTIONS OF SOME NEW SPECIES OF CLYTHRID^ 

 AND EUMOLPID.E. 



By Maktin Jacoby, F.E.S. 



Tellena angusticollis, n. sp. 



Elongate, subcylindrical, metallic green ; antennae black ; thorax 

 narrowed in front, closely and finely punctured; elytra extremely, 

 closely punctured and finely rugose. Length 8-10 mill. 



Head rather closely and finely punctured, with a deep depression 

 between the eyes, the latter elongate, notched at the inner margin ; 

 labrum and mandibles black ; autennre, scarcely extending beyond the 

 base of the thorax, black, the first joint metalhc green, the following 

 two joints also stained with metallic blue, very small, the others 

 strongly serrate ; thorax twice as broad as long, the sides rounded and 

 distinctly narrowed in front, with a narrow refiexed margin, the sur- 

 face closely impressed witii fine and larger punctures ; scutellum very 

 broad, finely punctured ; elytra more closely but scarcely more 

 strongly punctured than tlie thorax, the interstices finely transversely 

 wrinkled ; under side metallic green, like the upper surface, but 

 clothed with fine grey pubescence, thickly so on the abdominal 

 segments ; legs long and slender, the tarsi black, claws bifid. 



Hab. — Brazils, St. Paulo. 



This species has no doubt been confounded with the only 

 other one which constitutes the genus, but it is quite distinct, 

 although the resemblance is very great. 



Lacordaire, who has described the type T. varians, has 

 already drawn attention to the great variability of the insect, 

 and says that one could easily separate two species, if only the 

 extreme forms were before one; but he only founded these 

 remarks on the sculpture of the thorax and the elytra ; and it is 

 probable that he overlooked the shape of the thorax, although 

 this is difficult to imagine in an author so experienced as 

 Lacordaire. In any case, I have before me three specimens, 

 which not only differ in the finely rugose elytra, of which 1 

 cannot see a trace in the typical form, but in which the thorax 

 is distinctly narrowed in front, the same part in T. varians 

 showing an equal width in all the specimens I have for examina- 

 tion, so that the thorax may almost be described as transversely 

 subquadrate. This, I think, justifies my separating the two 

 insects, especially as it is not a solitary case. 



Urodera lacordairei, n. sp. 



Black, closely pubescent below ; antennae and legs fulvous ; 

 thorax very closely punctured, transverse ; elytra finely punctate- 

 striate, the interstices sparingly punctured, the sides, base, and apex 

 with a narrow fulvous band extending inwards to the middle of the 

 suture. Length 6 mill. 



Head nearly flat, slightly bronze- coloured, very closely and finely
