terior tibiae are widened and strongly cannate; the presternum 

 and mesosternum in all are proportionably broad. 



4. Lamprosphaerus quadrimaculatus, sp. n. — Piceous, antennae 

 and legs rlavous, head and thorax finely punctured with aeneous 

 gloss, elytra rlavous, closely punctate-striate, the punctures pi- 

 ceous, the suturai margin, a small spot at the base and another 

 below the middle, obscure aeneous. 



Length 3 mill. 



Head obscure aeneous, finely and remotely punctured, longi- 

 tudinally grooved between the eyes, the anterior margin of the 

 clypeus nearly straight, palpi and antennae rlavous, the latter 

 extending to the middle of the elytra , very slender , the third 

 and the following joints nearly equal in length ; thorax twice 

 as broad as long, widened at the middle, the sides rounded, 

 slightly narrowed, in front, the surface finely and rather closely 

 punctured, obscure fulvous with a strong aeneous gloss, scutel- 

 lum obscure aeneous, elytra very convex, more strongly punc- 

 tured than the thorax, flavous, the interior of the punctures, 

 piceous, the latter arranged in rather closely approached regular 

 rows, the suturai margin narrowly and the lateral one more

Of brownish-aeneous or cupreous colour, the head finely and
