Genus Ceramioides Saussure 



J*. Eyes very distant from each other and from the ocelli formed on 

 the vertex, their inner margins very broadly and shallowly emarginate, 

 but little more than sinuate; clypeus flat, longer than broad, its an- 

 terior margin produced and squarely truncate ; mandibles ratlier broad 

 and flat, two teeth on the inner margin before the apex, labial palpi 

 4-segmented. Antennae long and slender, of 12 segments, a very little 

 widened before the apex, the eleventh segment longer than broad, the 

 twelfth more than twice as long as the eleventh, tapered and recurved, 

 forming an apical hook. 



Humeri entirely rounded ; parapsidal furrows weak anteriorly but 

 forming two deep grooves near the middle line just before the scutel- 

 lum; tegulae short, scale-like, not covering the base of the scutellum, 

 impunctate; disc of scutellum flat, posteriorly broadly rounded, cover- 

 ing a2id concealing the rounded postscutellum ; posterior face of propo- 

 deum small, flat, rounded into the sides below, but superiorly sharply 

 truncate. 



In the forewings m-cu inserted shortly basad of M^ -{- Cuj, Cu^ at 

 the point of insertion of m-cu turning caudad for a short way to meet 

 M4. Anterior trochanter produced at apex into an elongate scale, 

 tibiae and femora with even surfaces except that the anterior femur 

 is widened beneath before the middle ; middle tibia with a single spur 

 at apex; larger posterior tibial spur with two spines and a tooth on 

 its margin toward the apex; claws with a small tooth on the inner 

 margin at its middle. 



Abdomen subcylindrical, flattened beneath, the second, third, and 

 fourth dorsal segments somewhat constricted basally ; the last dorsal 

 segment rounded and unarmed ; the third ventral segment armed with 

 two tubercles ; the seventh ventral segment posteriorly produced ven- 

 trad and pointed. 



5. Differs from the male in the following particulars: clypeus with 

 its anterior margin broadly rounded, indistinctly separated from the 

 front, antennae much shorter, weakly incrassate from the third seg- 

 ment to the apex, the apical segment as broad as long, no longer than 

 the preceding, the third segment more than twice as long as the pedicel, 

 longer than segments 4 and 5 ; tooth of the claws larger ; second ventral 

 segment unarmed and last ventral apically simple and rounded.
