segments less closely ]-)iinctiirccl towards tlicir hind marg-ins, 

 so as to be a little shining. 

 Tapajos; a single individual. 



2. CEdodacti/Ius anceps, n. sp. Bnmneiis, opacus, 

 dense punctatus; thorace minus elongato, basi rotundato, 

 antennis pedibnsque testiiceis. Long. corp. 2^ lin. 



Antennre yellow, moderately long, slender; 2nd joint 

 longer than the very slender 3rd joint ; joints 4 — 1 1 each 

 very slender at the base, and longer than broad. JNIaxil- 

 lary ])alpi yellow, last joint less produced inwardly than in 

 CE. errans. Head small, narrower than the thorax, closely 

 and rather coarsely but not deeply punctured, the interstices 

 slightly shining. Thorax about as long as broad, Avith 

 the base rounded, so that the hind angles have disa])peared ; 

 it is slightly loljcd in the middle iu front, the front angles 

 nearly right angles; it is densely punctured, the punc- 

 tures on the middle shallow, subocellate, the sculpture at 

 the sides and base granular. Elvtra a little long-er than 

 the thorax, dull, densely punctured with an asperate 

 punctuation. Hind body slender and elongate, pointed at 

 the extremity, densely punctured. Legs rather long, 

 yellow, front tarsi elongate and (for the group PinopJnlini) 



narrow. 



Tapajos; a single individual. It is, I believe, a male, 

 but the extremity of the hind body is retracted, and I 

 have damaged the specimen in trying to withdraw it. 



QilDICIIIRUS. 



This genus has not been registered as found in the New 

 "World, but my collection contains six or eight species 

 from South America. According to a note of jNIr. Bates 

 the Gl. optatns here described is found on trees. 



1 believe the Khitrolxeua (jenicuhitiis, Sahll)erg, from 

 description (.Vet. Soc. Fenn. 2, ]). 802), to be an insect of 

 this genus, the characters mentioned as separating the 

 genus from CEdic/drus appearing to me very indefinite. 

 Amongst these, Sahll)eig lays stress on the last joint of 

 the antcnnic terminaiing in a s])ine. On examining the 

 European (LJ. jxcderinus, 1 find that in some individuals 

 the anteniiiu end in a short spine or seta; and of the 

 three specimens 1 possess of CE. opttdus, the two females 

 have the extremity of the antenna* truncate, while in the 

 male these oi-gans are terminated by a slender but rather
