last dorsal segment, in addition to the four tubercles bordering its 

 truncate apex, has a pair of tubercles on the dorsal surface. 



5. A sharp transverse carina between the antennae ; clypeus very 

 convex and rugose ; labial palpi 2-segmented, the first more than twice 

 as long as the second, maxillary palpus very short and conical. 



Anterior femur flattened beneath, the tibia with a weakly irregular 

 undersurface as long as the tarsus; the latter without a fringe of 

 ciliae ; the metatarsus one-half as long again as the remaining segments 

 united ; the fourth segment broader than long ; middle femur flattened 

 beneath; the tibia slightly flattened beneath, not irregular, but con- 

 stricted at base, the outer surface bearing scattered short spines, very 

 slightly shorter than the tarsus, bearing 1 apical spine ; metatarsus as 

 long as the following segments together, the fourth about as long as 

 broad ; posterior tibia about one-third shorter than its tarsus, the apical 

 spur bifid ; metatarsus one-half as long again as the remaining segments 

 united, not noticeably curved and without an apical lobe, the fourth 

 segment about as long as broad. 



Abdomen unarmed.

(^. Front rugosely punctured, raised below the front ocellus, with 

 a transverse ridge between the antennae, which is polished and impunc- 

 tate ; clypeus very convex, its disc polished and with few large punc- 

 tures, its sides with close, smaller punctures and somewhat wrinkled. 



Humeri prominent, but not angled, without a distinct humeral 

 ridge ; mesonotum anteriorly closely punctate, and with a median 

 ridge posteriorly with two lateral ridges between which it is depressed, 

 smooth and polished, with only minute shallow and sparse punctua- 

 tion ; scutellum prominent, polished and practically impunctate. 



Basal abdominal segments strongly constricted at base, closely and 

 finely punctate, a median area at base of each except the first two, 

 impunctate, polished ; medial punctures finer toward the apex of each 

 segment ; second ventral segment with two anterior tubercles and two 

 weak ones behind ; third ventral segment with a strong tricuspid 

 prominence.
