]fl. Tlilpecnlus Fah.— Our largest Ceutorhynchid. Broadly ovate, above 

 densely clothed with black scales; underside of body, sides of prothorax and 

 sutural line, with fulvous scales. Length 4.5-5.0 mm. ; 0.18-0.20 inch. 



Hab. — Atlantic slope. 



The male has the pygidiuni protuberant, the fifth ventral segment 

 strongly foveate and the middle and posterior tibise strongly ungu- 

 iculate at the apex. Female : pygidium excavate, fifth ventral very 

 convex and protuberant towards the apex ; tibi?e not armed at the 

 apex. As the description of this species by Fabricius antedates 

 that of Boheraan, I accord to the former the authority. 



Snbtribe Cceliodes. 



In all the species of this subtribe the sternal canal extends upon 

 the mesosternum, more rarely the metasternura. The eyes are more 

 or less completely covered in repose by prothoracic lobes ; beak some- 

 what variable, generally long and rather slender, the antennal funicle 

 7-jointed ; sternal side-pieces wide, middle coxal cavities open or 

 closed within, ventral segments variable ; the legs are long and 

 slender, femora moderately stout, rarely {Orchestomerus) dilated, 

 more or less deeply grooved beneath for the partial reception of the 

 tibise in repose, except Acallodes and Qeliodes ; tarsi slender, third 

 joint bilobed, tarsi with two claws, the latter armed with a tooth of 

 variable length. 



The following genera are indicated : 



Second ventral segment shorter at the middle than the two following united, 

 prolonged at the sides, third segment narrowed at its extremities, 

 not or narrowly attaining the lateral margin ; femora mutic, grooved 

 for the reception of the tibiai. PI. xii, fig. 1. 

 Tibije flattened, acutely angulate or dentate near the base. PI. xii. fig. 2. 



Pectoral canal extending upon the nietasternum CrapuiiiiiM. 



Pectoral canal not extending upon the metasteruum I'lieniogouiis. 



Tibiae not flattened nor dentate near the base. 



Outer angle of anterior tibiic produced into a toothed process. PI. xii, fig. 9.
