outer lobe elongated, with two indistinct teeth above ; 4 posterior with a rough ridge 

 across the middle j tarsi slender and pilose, 4 basal joints gradually decreasing in 

 length, 5th long and clavate ; claws bifid at the apex. 



This little insect from Rio Janeiro seems to connect Plectr'is with Ceraspis, 

 and has so much the habit of a group of Brazilian HopUtce, that I had at one 

 time included it with them. 



*89. Macrodactylus marmoratus, Curt. 



Subcastaneus, pilis albidis vestitus, thoracis disco brunneo linea pilorum al- 

 bidorum centrali, elytris fasciis brunneis irregularibus pubescentiseque 

 albidae maculis notatis. 



Length 3^ lines, breadth 1^. 



Pale ferruginous, shining, roughish, with whitish pubescence : palpi and sometimes the an- 

 tennae piceous, terminal joint of former stoutish, subovate : clypeus and head punc- 

 tured, the former semiorbicular, the margin reflexed, the latter dark : thorax with the 

 centre dark brown, leaving the sides and a line down the middle whitish with hairs^ 

 not broad, suborbicular, narrowed a little in front and truncated, base slightly convex ; 

 scutel whitish, small and semiovate : elytra scarcely broader than the thorax, more than 

 twice as long, elliptic, rugose, with 4 elevated lines on each, vanishing at the apex, 

 which is slightly gibbose, variegated with piceous at the base, middle and towards the 

 apex, the spaces between with patches of whitish hairs : pygidium exposed, hairy and 

 partially piceous ; underside more or less piceous, clothed with pale hairs : legs dark 

 chestnut ; anterior tibiae with 2 external lobes ; tarsi slender ; claws with a tooth be- 

 hind the apex. 



Two specimens were taken at Chiloe. 



Philochlcema aula is the only authentic species I have of that genus, which 

 I suspect contains an undigested niass of incongruous materials; and as that 

 insect has simple claws, I have considered this species as a section oi Macro- 

 dactyla, with the clypeus less elongated, the sides of the thorax not dilated, 

 and the legs less sprawling. It will form a very natural transition to Ceraspis, 

 having a good deal the figure of C. peruvianus of Guerin. 



Section Anthobii or Glaphyrid^.
