244 ME. M. JACOBT ON THE [Teb. 2, 



Pedeillia. madagascaeiensis, n. sp. 



Fulvous, pubescent ; the apical six joints of the antennae, the 

 apex of the tibia?, and the tarsi, black; thorax finely, elytra 

 strongly punctured. 



Length Ig line. 



Head broad, very sparingly and finely punctured, with some few 

 hairs; clypeus narrow, semicircular; antennae widely separated at 

 the base, extending scarcely beyond the base of the elytra, fulvous, 

 the terminal seven joints black ; thorax but slightly broader than 

 long, co7)stricted below the middle, the latter projecting angularly, 

 the disc ^^-ith a shallow transverse groove near the base, the sides 

 below the groove thickened, with some stiff" hairs, the surface 

 finely and remotely punctured, each puncture provided with a 

 blackish stiff hair ; scutelkim subtriangular, punctured and pubes- 

 cent ; elytra slightly flattened along the suture, broader at the base 

 than the thorax, much more strongly punctured than the latter and 

 sparingly clothed with yellowish hairs ; underside and legs fulvous ; 

 the apex of the posterior femora, (sometimes) that of the tibiae and 

 the tarsi, black. 



Hah. Madagascar, Diego-Suarez {Alluaud). 

 This is the first species of the genus known to me from this 

 locality. In the collection of M. Alluaud and my own. 



HEMTDAClSrB, n. g. 



Elongate, parallel : head broad, not constricted ; antennae widely 

 separated, filiform ; eyes small, sUghtly emarginate; thorax narrowed 

 at the base, without lateral margin ; elytra wider than the thorax, 

 deeply punctate-striate : first two abdominal segments much longer 

 than the following ones ; posterior femora slightly incrassate ; 

 the four posterior tibiae with a tooth near the apex ; the first tarsal 

 joint as long as the two follo^nng ones, claws appendiculate ; 

 presternum proportionately broad, j^et twice as long as broad, its 

 base truncate. 



The insect for which this genus is proposed is difficult to place 

 in any of the earlier groups of Phytophaga, since it exhibits a 

 number of characters peculiar to several of them ; thus the widely 

 separated antennae and the broad head agree with Mcgascelis, the 

 thorax is somewhat similar to Orsodacna, but the broad prosternum 

 and the posterior tibiae widened into a tooth at the apex are not 

 found amongst any of these sections. The insect had perhaps best 

 find its place near Orsodacna at present, but would form a special 

 group if other similarly structured species should be found. 



Heiitdacne maculicollis, n. sp. (Plate XVII. fig. 3.) 



Below black, above and the legs testaceous ; head with one, the 

 thorax with two black spots, remotely punctured ; elytra deeply 

 punctate-striate ; the interstices longitudinally costate, flavous, the 

 suture black. 



Length lj-2 lines.
