into :i much larger, transverse, horizontally extended, foliaceous plate, the 

 broad caudal margin of which is irregularly convex with a distinct bilobation 

 indicated mesad; four carinulae, such as the two shown on the first segment, 

 occur. Third dorsal abdominal segment with a very much smaller, horizon- 

 tally extended, foliaceous plate; sixth with a similar but slightly larger plate 

 and with two parallel dorsal carinae; other dorsal abdominal segments unarmed. 

 Ninth (distal) dorsal abdominal segment with a medio-longitudinal carina and 

 two lateral carinulae concave-divergent caudad, lateral margins caudad 

 broadly convex-convergent to the minutely angulate-emarginate apex. \'en- 

 tral surface rugulose, nodulose and moderately supplied with nodes. Oper- 

 culum much as in L. spinicoliis here described, but with apex only moderately 

 rotundato-emarginate. Cephalic femora weakly laminate, carinae very de- 

 cided, dorso-lateral carinae of these portions and also the dorso-internal 

 carina of the cephalic tibiae feebly undulate, dorso-external carina of cephalic 

 tibiae supplied with (two and three) very minute and widely spaced lobes. 

 INIedian and caudal femora with a moderately large, bilobate production of dor- 

 sal carinae proximad and two similar, smaller bilobate productions distad, the 

 lobes of the caudal carinae being the more decided. Median and caudal tibiae 

 with dorsal carinae supplied with (two external and one internal) very minute 

 lobes, these no more decided than those of the cephalic tibiae. Well-developed 

 aroha present between the delicate tarsal claws. 



Length of body, 49.5; excrescence of occiput, 1.6; pronotum, 2.8; mesonotum, 

 12.2; metanotum, including median segment, 7.6; lobe of first abdominal seg- 

 ment, 1.1; lobe of second segment, 2.4; lobe of seventh segment, 1.2; cephalic 

 femur, 13.1 ; median femur, 10; caudal femur, 12.8; operculum, 7.7 mm. Uidth 

 of pronotum, caudad, 2.1; mesonotum, caudad, 2.9; lobe of first abdominal 

 segment, 3.1; lobe of second segment, 5; lobe of seventh segment, 1.1; cephalic 

 femur at widest point, 1.2 mm. 



General coloration light ochraceou.s-buff, feelily maculate and speckled 

 with bone brown, with a suffusion of this color over the proximal and me.so- 

 distal portions of the abdomen (possibly due to discoloration). Occipital 

 excrescence blackish, contrasting strongly with the head coloration which is 

 ochraceous-buff, with a suffused postocular band of bone brown on each side. 

 Lobes on abdomen and limbs bone brown. Ventral surface of body and limbs 

 light ochraceous-buff, heavily suffused with lione brown. 



The type is unique.
