Inhabits North America. The Linnean description of this insect is 

 worded thus: — "Thorace mutico, cyhndrico, inaequali, elytris apice 

 bidentatis, albo irroratis, antennis longioribus aculeatis." 



Fabricius thus describes it: — "St. thorace mutico, insequah, elytris 

 apice bidentatis, albo-irroratis, antennis longis aculeatis." Drury's 

 figure, quoted by Fabricius, appears to have two spines on several 

 joints of the antennae, and in other respects to differ fi*om the following 

 insect, which I formerly supposed to be the Cerambyx irroi'atus of Fabri- 

 cius. In the Banksian collection, named by Fabricius, the specimens 

 appear to me to be identical with the Cerambyx glabratus of Fabricius 

 described below. Until the original insect can be examined, I think it 

 better to leave the name irroratum unattached to any of the sjjecies 

 with which I am acquainted.

 Inhabits Brazil. A specimen is in the cabinet of the Entomologi- 

 cal Club. The prothorax is somewhat rugose and punctured, with 

 the exception of a median elevated line, and four tubercular points, 

 two on each side of the median line, forming a kind of square ; the 

 line and points are glabrous, the rugose parts are covered with a grey 

 pilosity : the elytra are deeply and irregularly punctured, the punc- 

 tures somewhat decreasing in size towards the apex : the pilosity is 

 somewhat symmetrically arranged in patches. 



Elaph. ordinatum. Ferrugineo-fiiscum, punctum, lanugine cana 

 maculatum: antennae corpore longiores, articulis 3 — 8 a23ice 1-

Inhabits Brazil. There is a specimen in the cabinet of the Ento- 

 mological Club. It is a broad and rather depressed insect ; the protho- 

 rax is deeply and rugosely punctured, with the anterior and posterior 

 margins, a median longitudinal line, and two somewhat amoi'phous 

 spots on each side, glabrous : the elytra are deeply punctured ; the 

 punctures are crowded in the region of the scutellum, more distant 

 towards the middle and side, and much smaller towards the apex ; the
