Protliorax, in front, .slo])in!;' i'lom tlie mitt'riiir end, on the 

 ventral slope provided witli tlie lipdikc lohcs and the transverse 

 slit thron.oii which tlie head-capsule is exserted. The upper lip 

 is the higher, not strongly chitinized, provided with a few small 

 scnilcrcd hrislles which are more numerous on the sides of the 

 l(il)f; lower lip not so high, with small scattered bristles that are 

 not arranged in a row as in glahrata. At the angle of the slit 

 is a small rounded lobe bearing a small bristle. Dorsal body 

 a])pendages reduced to a pair of lolies in front s(>]iarat('d by a 

 si)ace a little wider than one of thcni, and a jiair of smaller ones 

 lieliind \ery widely separated. Lateral body ajipendage long, 

 coiispiciions. V(>iitral body ayipendages not a])par('nt. 



Meso- and metathoraces swollen and arched ventrally like the 

 prothorax. Dorsal appendages two, a small conical one in front 

 and a much larger one behind which bears a small tooth in front 

 and with its tip directed backward. Lateral appendages viewed 

 from above, two in number, the anterior one larger, directed 

 shaiply backward, the second smaller, conical. \'entral appen- 

 dages viewed from the side, two, of which the anterior one is 

 the lai-ger, the posterior pair small, slightly behind the others. 



.Midominal segments, dorsal a]ipendages : first segment M'ith 

 two pairs of appendages, the anterior shorter, conical, the tip 

 stiongly recurved and bearing a tiny tooth on its anterior face 

 at about midlength; the posterior are nmch longer with the tip 

 hcut strongly backward, a small tooth (Ui the anterior lace at 

 ahout one-third the length. Segiueuts U to \'ll with foui- j.airs 

 of apjieuda-es. the lirst vei-y suudl, conical; the second exactly 

 similai- imt larger; the third and foni'th similar to those 

 ai)i)eudages of the first abdominal segment: the tiny first 

 appendage is largest on the second segment, lieconiing smaller 

 toward the end of the body. Lateral appendages: lirst segment 

 witli three appendages, the first of which is directed laterad, the 

 posterior two more recurved and directed caudad. Segments 

 1 1 to \'1I with four i)airs of lateral ai)pendages of which the first 

 is very small, situated at the antero-lateral angle of the segment, 

 the other three teeth are suiuMiual and directed cauda<l. \'cuti-al
