Wesmael), setaceous, uot dilated and compressed beyond the 

 middle, nor suddenly attenuated at the apex. The other differences 

 are less obvious; abdomen broader, more obtuse behind, the apex 

 subtruncate, channelled beneath to receive the point of the terebra ; 

 base with 2 small triangular yellowish spots not touching the 

 reflexed edges, which ai-e also yellowish for a short distance ; 2 

 faint basal carinae not reaching the pale spots. Metathorax 

 strongly bidenticulate, and with 2 blunter lateral angulations. 

 Terebra concealed. Wings as in the preceding species ; costa, 

 basal nervures, and parastigma testaceous, the latter with a fuscous 

 spot. I have not seen the <? , which, according to Wesmael, is like 

 the 2 , and with similar antennae, but 29 — 30-jointed. $ $ . 

 Length, 2^ ; wings, 4^ lin. 



More robust than C. inanitus, L., and evidently dis- 

 tinct. The antennae alone lead me to conclude that it 

 is the real suhmuticits, Wesm., for the other characters 

 given by him are not likely to be constant. The meta- 

 thorax is more strongly bidenticulate than in Wesmael's 

 description, and the basal carina of the abdomen more 

 feeble ; all the characters, however, are present. As the 

 cheeks are not dilated, it cannot be C. hiiccatiis, Thoms., 

 which that writer compares, as to its antennae and 

 metathorax, with suhmuticus, Wesm. 



One female is in Fitch's collection. 



Bridgman captured, at Brundall, Norfolk, a ^ closely 

 resembling the above ? , except that the antennae are 

 25-jointed. It is no doubt a different species, which I 

 am unable to name, or to describe intelligibly without 

 more specimens, including the other sex.

 Chelonus Wesmaelii, Cur., B. E., pi. dclxxii., 3" . 



Black ; palpi testaceous ; abdomen bright rufo-testaceous above 

 for f of its length, with a black medial stripe, sometimes inter- 

 rupted ; legs rufo-testaceous, coxas and trochanters black, hind 

 femora and tibiae narrowly at the apex, and all the tarsi except 

 their basal joint, fuscous. Wings fuscescent, longer and narrower 

 than in the two preceding species, with a whitish streak beneath 

 the attenuated stigma ; radial areolet elongate, acuminate, the 3d 

 abscissa almost straight ; radius of the hind wings curved. Eugose, 

 piibescent; antennae <? as long as the body, 32 — 34-jointed. 3. 

 Length, 3 ; wings, 4f lui.
