and dentate ; dorsum rugose and on posterior process rugose- 

 reticulose ; humeral angles not prominent and widely subrounded, 

 process lengthily subulate, apex little upturned and acute, extended 

 beyond the apices of posterior femora ; lateral lobes posteriorly 

 bisinuate, posterior angles distinctly laminate and terminating in a 

 laterally produced obtuse denticle, behind minutely serrulate, 

 truncate. Elytra of moderate size, externally punctate, substraight 

 or concave above, strongly arcuate below, apices narrowly rounded ; 

 wings fully explicate reaching nearly to the apex of pronotal 

 process. Anterior and middle femora elongate, margins sinuate 

 sublobate, superior carinae of middle tibias compi'esso-dentate at the 

 middle ; margins of posterior femora minutely serrulate and sinuate- 

 dentate, the antegenicular and genicular lobes stout and prominent ; 

 hind tibi£e fuscous, the margins lightly serrulate' and armed with 

 rather obtuse spines, the first articles of the posterior tarsi having 

 the third obtuse pulvilli little longer than the second. 



Entire length of body, female, 14 mm. ; pronotum 13 mm. ; 

 antennae 4'5 mm. ; post, femora 6 mm.

2. L. alticristatus, sp. nov. 



Differing from the preceding species in the darker almost black 

 body, slightly tomentose below, in the dorsum bearing a much 

 higher foliaceous crest, and in the obliquely truncate laminate sub- 

 acute posterior angles of lateral lobes of pronotum, scarcely at all 

 dentate produced laterally. 



Body rugose ; vertex very wide, transverse ; eyes substylate ; the 

 transverse frontal carinula3 obsolete. Antenna3 black and pale 

 annulate at the joints, articles strongly dilated towards the in- 

 dividual apices and margins minutely serrulate and pilose ; maxill- 

 ary palpi having the two last articles flattened, dilated, the 

 penultimate article oval, pilose. Pronotum anteriorly truncate, 

 posteriorly subulate, and little longitudinally concave ; dorsal crest 

 strongly elevated between the shoulders equal to three and a half 

 millimeters above the humeral angles, margin not at all sulcate, 

 viewed in profile the front margin vertical erose and flush with the 

 anterior border of the pronotum, the convex dorsal margin sloping 

 backward and reaching as far as the middle of the wings, forward 

 minutely denticulate and sinuate, behind dentate, viewed from 

 above strongly sinuate, dorsum on either side and on the process 

 lightly reticulate. Wings fully explicate, reaching scarcely beyond 

 the pronotal apex ; elytra having venate marking, punctate, and
