triquetrous and fully one-half as long as the funicle; the latter six-jointed, 
each joint much broader than long, the first much the smallest, it being 
considerably narrower than the apex of the pedicel, the following joints 
becoming successively much broader, but hardly increasing in length; club 
solid, somewhat greater in length and bulk than the funicle, but only 
slightly wider than the preceding joint, suboval in shape, the apex obliquely 
and roundingly subtruncate beneath. Mandibles very slender, obscurely 
tridentate at apex, there being a prominent, very acute median tooth 
flanked on both sides by a much smaller tooth, the inner or dorsal one 
forming nearly a right angle with the inner margin of the mandible. 
Palpi short, maxillary pair four-jointed, apical joint about as long as the 
basal three combined, acute and with long hairs at apex, the second longest 
of the other three joints; labial pair three-jointed, the basal joint longest 
and over twice as long as the second, which is shortest; apical joint blunt 
at apex, with shorter hairs than on maxillary palpi. 
Thorax moderately robust and convex above, increasing in width behind 
the tegulae; pronotum large, anteriorly conical, the collar as long as the 
mesoscutum, its posterior margin only slightly arcuate; mesoscutum short 
and transverse, about twice as wide as long, its anterior corners foyeate; 
axillae well developed, not greatly wider than long, their inner tips acute 
and meeting medially or nearly so, their outer sides abruptly declivous; 
scutellum as long as the mesoscutum, five-sided, the apex being rather 
broadly truncate, the sides abruptly declivous and forming a sharp margin 
with the disk, the latter distinctly, although not deeply, concave except at 
apex, and sloping backward; propodeum large, sloping obliquely backward, 
hardly longer at the sides than at the middle, the spiracles small and 
almost circular. 

Coelaspidia osborni.
