Episforiia trapezoidal ; its anterior angles rounded. Labrum longer than 

 broad, narrowed at the base, broadest before the middle and again narrow- 

 ed towards the tip, which is truncated and beset with golden pubescence. 

 Mandibles very stovit at the base, pointed at tip. almost pyramidal ; they 

 have no indentations; they are but little excavated on the inside and their 

 tip is but very slightly curved. Mnxillse: stout cardinal piece, short, trans- 

 verse basal piece, a small, coriaceous, bristly lobe, and a 3-joiuted palpus, 

 projecting beyond this lobe. Mcntmn transverse, rounded on the sides; 

 palpigerous piece small, bilobed, each lobe bearing a short, 2-jointed pal- 

 pus; Ungud very much developed, prolonged inside of the mouth and con- 

 sisting of two coriaceous lobes, pubescent along the margins and connate 

 on their flat surfaces, the margins only remaining free (this can be per- 

 ceived only by dissection). Antennse short, apparently l-jointed; first 

 joint the largest, second joint as if immersed or retractile in the first, third 

 but little longer, fourth minute and narrow. 



Prothorax yellowish, brown on the anterior margin; its underside shows 

 three triangular pieces separated by distinct sutures; at the posterior cor- 

 ners of the middle one the feet are inserted on a pair of fleshy tubercles; 

 each side of the prothorax has also a triangular, elongated piece, placed 

 between the ventral and the dorsal horny plate; the latter is flat on the 

 back and recurved almost at right angles on the sides, so as to encroach 

 considerably on the lateral sides of the prothorax; its dorsal disc is limit- 

 ed on both sides by a longitudinal fold, tinged with brown, beginning at 

 the posterior margin, but not ([uite reaching the anterior one; the anterior 

 portion of this dorsal disc is smooth, the posterior one covered with fine, 

 bi'own. granulations more extended anteriorly in the middle than on the 

 sides; the posterior margin of this disc is abrupt, steep and smooth. The 

 middle triangle of the breast-plate has the same granulations on its poster- 

 ior half; they are also extended to a portion of the lateral triangles. 



The tiro (ithrr tJinracic !<i(jmrnfH are short, wrinkled; on the underside, 

 between the feet of each pair, two oblique wrinkles, connected by a trans- 

 verse furrow, may be observed. The feet are short and consist of a fleshy, 

 tubercular coxa, a short femur and tibia and an elongated nail. The first 

 pair of stigmata is placed on the sides of the mesothorax. 



The seven first dbdomlnrd sajmnifs have each, on the dorsal, as well as 

 the ventral side a fleshy protuberance, which is oblong on two or three an- 

 terior segments and more rounded on the others; being divided longitudi- 

 nally by a deep furrow, these protuberances appear double ; they have 

 besides, especially those on the anterior segments, a more or less distinct 

 transA^erse furrow and a pair of oblirjue wrinkle-^ on the sides. The eighth
