1)03. Ccelioxys ducalis, Smith, Cat. ii, p. 267, $ ; Dall. Ton: Cat. x, 



$ . Head densely pubescent, thorax very closely and finely 

 punctured ; the bases of the abdominal segments, and especially the 

 sides near the base, finely and closely, the apical margins coarsely 

 and more sparsely punctured, the apical segment above dull 

 opaque, very minutely and densely punctured ; clypeus subtrian- 

 gular, its anterior margin widely arched ; mesonotum with a medial 

 longitudinal, short and rather obscure carina on the disc posteriorly, 

 an impressed longitudinal line on each side of it and another 

 impressed longitudinal line at both sides near the tegulse ; apical 

 abdominal segment acutely narrowed, the ventral plate longer than 

 the dorsal and ciliated on each side with very short stiff hairs, 

 giving it the appearance of being minutely sen-ate. Black ; the 

 head covered with a rich fulvous pubescence, slightly fuscous on 

 the posterior margin of the cheeks ; antenna) piceous ; abdominal 

 segments 2-5 with indications of lateral white pubescent spots at 

 their bases ; wings dark fuscous, with a brilliant coppery efful-

2 . Closely allied to and resembling C. capitatus, Smith ; differs 

 in the head and thorax being more sparsely punctured, the front 

 from beneath the anterior ocellus to halfway down the clypeus 

 with a distinct fine carina, the pubescent spots on the mesonotum 

 .anteriorly and at the base of the scutellum wanting, the dorsal 

 plate of the apical abdominal segment much shorter than the 

 ventral, both tapering to a point. 



S similar to the female : differs from the male of C. ca^ntatus 

 in the apical segment being furnished with only four teeth or 

 spines and a lateral spine on the 5th ventral segment.

 5 . Head and thorax very broad, the former subquadrate, both 

 closely and very coarsely punctured ; abdomen acutely conical, 

 more finely punctured, the punctures on the basal segment 

 densest ; clypeus flat anteriorly, nearly transverse : scutellum with 

 two minute medial teeth and a large blunt tooth on each side at 

 the lateral angles posteriorly ; apical abdominal segment acutely 

 pointed, its dorsal plate medially carinate on its apical half, 

 ventral plate acutely pointed and notched at extreme apex, pro- 

 jecting considerably beyond the dorsal plate. Jet-black; the 

 clypeus thinly, the front, cheeks, two spots on the mesonotum 

 anteriorly, two spots at the base of the scutellum, one on each 

 tegula, the sides of the thorax, the legs more or less, and transverse
