S. Head black, with the clypeiis discreted and somewhat angularly 

 prominent apically. Antennae setaceous and longer than half the body. 

 Thorax black ; metathorax rugose, centrally longitudinally wrinkled with 

 the costulae indistinct ; peliolar area laterally curved and basally sub- 

 acuminate. Abdomen oblong-ovate and narrower than the thorax ; the 

 three first segments closely punctate apically and laterally, and the 

 following apically, red ; the basal segment obsoletely tuberculate, a[)ically 

 gradually dilated, laterally immaculate, with the post-petiole rather longer 

 than broad and obsoletely aciculate. Legs normal, red ; trochanters 

 except apices of the hind ones, and all the co.xae, black ; anterior femora 

 externally black-marked. Wings normal, hardly clouded ; stigma black, 

 tegulae dull ferrugineous ; radix flavescent, areolet wanting. Length, 

 4-6 mm. 



The conformation of the clypeus, which seems to relate it with C. 

 inimicus, and of the petiolar area are hardly sufficient to distinguish this 

 species. There is, however, a male in my collection which agrees with no 

 other known species, but possesses all the points enumerated above. To 

 them I would add that the head is buccate and entirely black, with only 

 the apices of the mandibles dull red, their teeth being sub-equal ; clypeus 

 convex, apically mutic and punctate, and distinctly discreted ; face and 

 vertex shortly pubescent and obsoletely punctate, with deeply impressed 

 genal sulcus and sub-prominent epistoma. The second flagellar joint is 

 not shorter than the first. Mesonotum obsoletely pubescent and punctu- 

 late, nitidulous with the notauli elongate, sub-coalesced discally but not 

 deeply impressed ; basal area broad, areola exactly hexagonal, truncate at 

 base and apex, emitting the obsolete costulae from its centre ; petiolar 

 area somewhat narrow, scabrous with no apophyses. Basal segment 

 scabrous throughout and hardly curved, with distinct tubercles, before 

 which it is bicarinate ; post-petiole not narrow, parallel-sided, obsoletely 

 aciculate and distinctly margined ; second segment closely and evenly 

 coriaceous, apically glabrous and sub-callose, with the thyridii sub- 

 transverse. Hind femora, apices of their tibiae and all the tarsi piceous. 



$. Agreeing in every \yay with the above $, excepting in the con- 

 formation of the basal segment and the coloration of the legs ; the 

 metathorax is identical in every particular, but the antennae are centrally 

 sub-incrassate and ferrugineous. The basal segment is apically broad, 

 gradually explanate throughout with the basal carinhe inconspicuous ; the 

 post-petiole is sub-convex and evenly coriaceous, with very slight traces of 

 aciculation, but distinctly margined laterally. Legs entirely fulvous with 

 only the hind coxae black. Terebra three-quarters the length of the 

 abdomen. Length, 3! mm. 



Both sexes strongly resemble H. crassicflrnis in outline, but the costulae 

 are obsolete and the areola a little longer than broad. The $ has the 

 post-petiole much broader, and in the ? , which is now for the first time 

 described, the abdominal coloration is definite, with the antennae more 

 slender.
