specimens were not prepared for such investigations and I cannot be 
sure. There is an excellent field here for the histologist or close anatom- 
ical student, rather than for the mere systematist to whom structure, is 
valuable mainly from the assistance it gives him in the classification of 
the specimens.

A Plague of Psocids! 
Somewhere recently,—I think in ‘‘Insect Life,” but have not the 
paper handy—there appeared an account of an invasion of Psocids, 
which it was found almost impossible to get rid of. Two exactly similar 
cases came under my notice in New Jersey, but a few days ago, causing 
considerable dismay since they were considered small forms of Pediculus 
vestiment left as a legacy by tramps who had been sheltered. ‘They ap- 
peared suddenly and in immense numbers, covering the beds, invading 
clothes presses, congregating on the walls and filling corners. The neat 
housewife was dismayed, and every remedy known in the battery of 
housecleaning was brought to bear upon them. The slaughter was 
great, but so was the supply. Of course the supposed cause of this un- 
usual house-cleaning was carefully kept secret, and imparted to me only 
in the strictest confidence, together with a mutilated specimen for exam- 
ination. Though not sufficiently perfect to identify the species, there 
was enough of the specimen to enlighten me as to the nature of the 
attack, and to enable me to afford consolation and advice. I have 
found that where they appeared on a small scale, naphthaline is a 
sovereign remedy for Psocids, and I have no doubt it will work equally 
well on a larger scale.
