tinge, and my only female has ihe darkest markings almost black, as dark, 

 in fact, as the darkest in Prionoxystus robinice in the figure Dr. Holland 

 shows just above this species. The ochreous Didsbury specimen I picked 

 out of about a score of pale ochreous and salmon-tinted ^f-guttattcs and 

 smoky-gray and brown argenteomacidatus as the nearest approach I ever 

 saw to a connecting link between the two. It is, in fact, about" inter- 

 mediate, though I saw no intergrades with either extreme, and I was much 

 surprised to find that it so closely resembled the figure in the " Moth 

 Book." Flies at dusk in July. 



568. S. quadrigiittatus, Grt. — Fairly common some years, and 

 seems to be generally distributed where there are willows, on the roots 

 and in the stems of which the larva feeds. Mr. Heath tells me that he 

 has found larvte in roots of several other shrubs as well. I have no 

 specimens quite as pale in ground colour as Dr. Holland's figure. Flies 

 at dusk in July. Sir George Hampson said of a specimen I sent him : 

 " Argent eomaculatiis, not qiiadi'igiittatus^'' but I have not further investi- 

 gated the matter. 



569. Hepialus hyperboreiis, Moschl ? — About twelve years ago I 

 used not to look upon this species as a rarity, but only one specimen has 

 been seen for a good many seasons, on October 3rd, 1897. This and 

 another defective specimen labelled ''1894" are all I have. Dr. Dyar 

 gave me the name gcuina, a European species of Hubner's, of which 

 hyperboretis was at that time considered a variety. My use of the above 

 name is not authentic. 



A RARE (Zk^\VA\}=^ PLATYNUS QUADRIMACULATUS, 



HORN. 



BY W. S. BLATCHLEY, INDIANAPOLIS, INDIANA. 



Among a collection of beetles made by the late Dr. F. Stein, of 

 Indianapolis, I found some years ago a specimen marked '^Platytius, sp ? 

 Indiana." Finding no description fitting it in Dr. Horn's revision of the 

 genus,* I sent it among other specimens for naming to Dr. E. A. 

 Schwarz, of the U. S. Division of Entomology. Under date of January 17, 

 1899, he wrote me that it was Platynus quadrimaculaius^ Horn; that it 

 "was not represented in the U. S. National Museum collection, and that 

 only a few specimens had ever been captured." 



On April 20, 1904, I was much pleased to find a second specimen 

 beneath a chunk on a wooded slope bordering the flood plain of the
