PIIASMID/E. CEROYS.

long and slender, considerably variegated in their colours ; 

 the anterior femora and tibiae irregularly spinose and ser- 

 rated ; the four hind femora with five or six spines on each 

 of their angles, that near the apex being the largest. The 

 middle right leg in the specimen drawn had apparently 

 been reproduced, being smaller than the opposite limb, and 

 destitute of spines. The size of the spines of the body 

 varies in different individuals. One specimen in Mr. Fry's 

 collection has the abdomen destitute of the lateral lobes, 

 whilst the dorsal lobes of the third, fourth and eighth 

 segments are larger than in the specimen which I have 

 figured.

Rufo-brunneus, opacus, irregulariter granulatus et lineo- 

 latus, subcylindricus, parallelus ; abdominis segmento 2do 

 foliolo erecto postice instructo, sequentibus tuberculis par- 

 vis in margine postico, segmento 9no paullo latiori, apice 

 4-dentato, lobo apicali minuto detccto ; fcmoribus iuterme- 

 diis foliolis tribus magnis rotundis instructis (fcem.).

Uniformly opake, red-brown, with the sides of the body 

 nearly parallel ; the entire surface of the body covered with 

 minute granules and short slight irregular lines. The head 

 is oblong and simple. The antennae nearly half the length 

 of the body and very slender. The mesothorax long and 

 slightly widened at its extremity, as is also the metathorax, 

 which has its hinder division very short and slightly indi- 

 cated. The second segment of the abdomen is furnished 

 with a large erect leaflet at its hinder margin, and the fol- 

 lowing segments are also furnished on their hind margins 

 with a series of small tubercles, from which run fine striolae 

 into the disc of the segment ; the ninth segment is slightly 

 wider than the rest, it has a small spine on each side, and 

 it is notched at its extremity, a small lobe appearing be- 

 tween the divisions. The operculum extends beneath the 

 seventh and eighth and base of the ninth dorsal segments. 

 The legs arc of moderate length ; the anterior simple, with 

 the femora curved at the base ; the intermediate femora are 

 furnished on the upper fore edge with three large rounded 

 leaflets, the hind edge being tuberculated ; the hind femora 

 are irregularly and slightly serrated, as are the four poste- 



rior tibiae. The basal joint of all the tarsi is nearly equal 

 to the three following in length. 



Obs. The specimen figured has the right middle leg 

 simple in its joints, being evidently a case of reproduction 

 of the limb, which had been accidentally broken off.

Mediocriter elongatus, subdepressus, opacus, totus obscure 

 brunneus, rugosus ; abdomine longitudinaliter striolato ; 

 eapite bituberculato ; antennis longis ; abdominis segmento 

 secundo foliolo magno semicirculari irregulari depresso, 

 femoribusque 4 posticis supra lobis tribus rotundatis in- 

 structis (fcem.).

Hab. In Columbia (D. Gaudichaud). Mus. Saunders. 



Entirely obscure ferruginous brown, opake, rugose, and 

 finely granulose, with a few larger granules dispersed irre- 

 gularly. The abdomen with several slightly elevated lon- 

 gitudinal dorsal lines. Ilead with two rugose erect tuber- 

 cles pointed at the tip between the eyes. Antennae long 

 and slender. Mesothorax gradually widened from the 

 front margin to the middle ; metathorax widest. Abdomen 

 with a broad semicircular membranous depressed lobe, with 

 irregular notched edges fixed on the hind margin of the 

 second segment, and extending over the base of the third, 

 which, as well as the fourth, fifth and sixth, has the two 

 central dorsal lineolae terminated in slightly produced 

 points ; the sixth segment is considerably widened at its 

 hinder margin, and the three terminal segments are gra- 

 dually narrowed ; the seventh having a deep oblique im- 

 pression on each side, with the two minute caudal styles 

 beneath. The operculum is but slightly swollen, but its 

 extremity is furnished with two slender erect points dilated 

 in the middle of their inner edge. The fore legs are mode- 

 rately long, with the femur and tibiae slightly lobed ; the 

 four hind legs are shorter, with the femora furnished on 

 their upper edge with three pairs of small semicircular de- 

 pressed leaflets, as well as with a subbasal and subapical 

 smaller lobe ; the tibiae are also furnished with two or three 

 distant smaller lobes.
