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 

 ihe 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 

 con^iderable dismay since they were considered small forms oi Pediculiis 

 vestimenti 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.
