THE CANADIAN ENTOMOLOGIST. 75 



The psychological connection of my cards written to Major Casey, 

 from March to June, 1901, is very simple, and I wonder why Major 

 Casey did not find it out himself. The paper containing his new note on 

 the genera Homceusa, Myrmobiota and So/iusa was entitled ^''Review of 

 the American Corylophidce, Crypiophagidce, Tritotnidce and Dermistidce, 

 with other studies,^' comprising 121 pages. I informed him on March 

 5th of the receipt of this paper, without suspecting that it contained 

 something about Homoeusa and Myrmobiota. Only myrmocophilous 

 genera being of special interest for me, I did not examine more closely 

 Major Casey's ample paper on Corylophidce. etc.; therefore, when I 

 asked Major Casey again (June ist) to send me his last paper, where he 

 explained the differences of Homoeusa and Myrmobiota, it was not 

 necessary for him to send me a second copy of his paper on Corylophidce, 

 etc., but he might have simply informed me that the paper in question was 

 pp. 53-55 of his study on Corylophidce. Instead of falling on this 

 very simple explanation of the appearing contradiction in my cards. Major 

 Casey has given them a rather injurious interpretation, which I much regret 

 for Major Casey's own sake. 



ARATUS LUTEOLUS, N. SP. 



BY REV. THOMAS W. FYLES, LEVIS, QUEBEC. 



Length, .35 inch. Head dark fawn colour, scabrous, much prolonged 

 between the antennae, the prolongation suggestive of the nose of the 

 moose. Eyes upon rounded elevations, black and protuberant. The 

 antennary spine stout, sharp and projecting. Antennae reddish brown 

 above, olivaceous beneath ; the joint next the spine distinct and square 

 cut and of greater diameter than that following it. Beak black, long, 

 extending between the front legs. Prothorax dark umber in colour^ 

 concave in fronts the concavity ending on either side with a short spine. 

 From the bases of these spines the sides (which are finely denticulated) 

 run direct to the widest part of the prothorax ; from thence they are 

 rounded to the back, forming a pair of clay-yellow epaulets, which extend 

 beyond the slightly-curved remainder of the back line. Down the middle 

 of the prothorax are two carince, nearly parallel, extending from back to 

 front. The shield is narrow at the ba.-^e, and runs back to an acute angle; 

 its margins are reflexed. The costal edge of each elytron forms a double 

 curve : it is first convex and then slightly concave. The corium is broad 

 at the base, narrowed beyond the shield, and rounded at the tips. It is
