CHRYSOMELID^ FROM SOUTH AMERICA. 183 



two-thirds of the elytra are fuscous, and the apex of the tibiae 

 and the tarsi are black. Whether these forms represent the 

 female sex of the present species, which I am inclined to believe, 

 or again another closely allied insect, more material will show. 



Megalopus brevipennis, sp. n. 



Narrow and short, flavous ; antennae black ; head with two trans- 

 verse bands; thorax very finely and closely punctured, with an M-shaped 

 mark ; elytra finely sericeous, the base flavous, the rest pale fuscous. 



Mas. Posterior femora fulvous, strongly incrassate, unarmed ; 

 tibiae robust, simple, slightly curved. Length 7 mill. 



Hab. Jalahy, Prov. Goyaz, Brazils. 



Head extremely closely and finely rugose, flavous ; the vertex and 

 a broad band between the eyes piceous, the latter triangularly but not 

 deeply notched; antennae black, the basal joint fulvous; thorax slightly 

 broader than long, subcylindrical, sculptured Uke the head, finely 

 pubescent, flavous, with an M-shaped dark brown mark ; scutellum 

 flavous ; elytra obliquely depressed below the base, the latter shining, 

 flavous, the rest of the surface clothed with short pale pubescence, 

 obscure fuscous, below flavous, the sides of the breast with an oblique 

 piceous stripe ; abdominal segments also marked with obscure fulvous 

 or piceous ; legs fulvous. 



This is a shorter species than any of the rest of the genus 

 with which I am acquainted, and of finely sericeous not shining 

 appearance. The femora of the male are unarmed. 



Otilea ornata, sp. n. 

 Elongate, narrowed posteriorly, fulvous, above metallic green, with 

 a fulvous stripe ; the apical joints of the antennae black ; thorax with 

 the lateral margins dentate, metallic green, the disc dark fulvous; elytra 

 similarly coloured, deeply foveolate punctate, the sides transversely rugose, 

 metallic green, a broad sutural stripe dark fulvous. Length 10 mill. 



Hah. Marcapata, Peru. 



Head very closely punctured, metallic green, deeply depressed 

 between the eyes, the depressions more strongly punctured ; labrum and 

 palpi fulvous ; antennae slender, fiUform, fulvous, the terminal five 

 joints black, third and following joints elongate, nearly equal ; thorax 

 strongly transverse, the lateral margins widened at the middle and 

 bidentate, the middle of the disc very deeply but not closely punctured, 

 fulvous, in shape of a broad band, the sides bright metallic green, deeply 

 and coarsely rugose and punctured, the rugosities partly confluent ; 

 scutellum metallic green ; elytra with two rows of deep punctures near 

 the suture, the sides very deeply and confluently foveolate punctate and 

 transversely rugose, metallic green, a broad, posteriorly narrowed sutural 

 band dark fulvous ; under side and legs fulvous, the first joint of the 

 posterior tarsi as long as the following joints together; prosternum 

 bilobed, narrowed medially. 



Of this very handsome and peculiarly marked species I re- 

 ceived lately a single apparently female specimen. 



(To be concluded.)
