nest under a root stored with grain and swarming with a small beetle like 

 Typhoea fumata, but which on examination proves to be a species of 

 Crypiophagus, probably undescribed. To his industry in this direction 

 is due the honor of the discovery of a strange blind Pselaphide beetle 

 living with ants {Aiiip/yopone pa/lipes), recently described by Dr. E. 

 Brendel under the name Amplyopoiiica., and for which he has created the 

 genus Anops. Bull. Lab. Nat. Hiht. St. Univers., Iowa II., 80. 



Ahcrac/s siituralis and aculeata Lee. These species were bred 

 together from hickory limbs deadened two years — the latter in great 

 abundance, the former sjiaringly. 1 was unable to ascertain whether the 

 larvae live under the bark in the sap wood, or l)ore more deeply from the 

 firMt. I could discover no galleries other than of Ckramesus icorice. The 

 beetles came forth from the m-.ddle of May till the first of July. The 

 species resemble each other gr^ atly, and while extremes may be readily 

 sei)arated by the difference in the striation of the elytra and pubescence, 

 yet individuals meet closely and are liable to be confounded. In general, 

 Suturalis is the more slender and elongated, has the elytra smoother, 

 less deeply striate and the pubescence more visible towards the apex, — 

 sometimes wanting, sometimes extending forward near!y as in aculeata in 

 which the hairs are claviform. They are about the same lengths, .xo 

 inch, though the latter being thicker appears the shorter. In both the 

 basal joint of the antennae is flattened, triangular, and in the male the 

 anterior margin and apex have a dense fringe of very long, pale yellowish 

 hair of peculiar structure. Each hair seems to have a central rachis from 

 which springs rows of long spiculae which project forward, each of which 

 in turn becomes the rachis of smaller spiculae. These hairs when viewed 

 under the low powers of a microscope are beautiful objects, appearing as 

 if composed of glass ; each basal joint has from 25 to 40 as near as can 

 be counted. When at rest the edge of the joint bearing them projects in 

 front giving the insect a formidable appearance. Were aculeata with 

 these strange appendages and clavate bristles magnified to the size of an 

 ox, it would be difficult to delineate an animal of more ferocious aspect. 

 Inhabiting, as they seem to do, the smaller limbs of dead trees, in an 

 economic sense they can scarcely be classed as injurious. 



The observed records of distribution are few, owing most probably 

 not to a scarcity of the insects, so much, as to their being neglected by 

 collectors, like many of the other species of Scolytidce. 



Suturalis is recorded from Illinois (boring in xanthoxylon twigs), 

 Michigan, Kansas, Louisiana. Aculeata^ from Virginia, Buffalo^ N.Y.
