five or six preceding joints together; the apical joint but little longer than the tenth; 

 thorax densely pubescent, so that its punctation is concealed; the pubescence pale, 

 but in certain light, appearing dark on middle parts, owing apparently to an admix- 

 ture of spots or patches of black pubescence; elytra not quite so densely pubescent as 

 the thorax; the pubescence black, but there is a conspicuous band of cinereous pubes- 

 cence near the base which at the suture is strongly angulated in front, so as to ap- 

 proach rather near to the scutellum; legs entirely red." 



Relation to Light 



Both the larvae and the mating beetles show a decided negative 

 relation to light. The latter, however, fly to the windows after ovi- 

 positing. The beetles may be collected in this way but it is of little 

 avail, since the eggs have already been deposited in closets or trunks, 

 etc. 



Control Measures 



Carbon bisulphide was found to be effective for the destruction of 

 both beetles and larvse in the trunks, but apparently the eggs were 

 not killed by it, for young larvse were discovered on some of the 

 contents two weeks later. After a second treatment with the carbon 

 bisulphide we found no further signs of the insects. To insure the 

 contents against further attack they were given a liberal supply of 

 flake naphthaline, scattered between the various garments. This 

 treatment lasts for a year or more if the trunks are not opened, and 

 no beetles will enter while the naphthaline is present. 



Treatment of clothing in closets of open houses, such as we have in 

 the tropics, is a more difficult matter. Fumigation is often out of the 

 question, and if moth-balls are used they require frequent 'renewal. 

 Fortunately, however, the clothing which is used frequently is not 

 subject to injury. Very satisfactory moth-proof bags are on the mar- 

 ket, and these come in such sizes that entire garments may be sus- 

 pended in them.
