is touched or jarred they feign death and fall off. The proper 

 name of this species is somewhat in doubt. C. irisie was described 

 from California and picicorne from "Pennsylvania to Georgia" by 

 LeConte on the same page. -Jayne says the two are synonyms. 

 Casey says triste is a west coast ■ species and that he has not seen 

 picicorne, but that it is probably a valid species. If the two are dis- 

 tinct, our species should bear the latter name. 



VII. Anthrenus G-eoff. 1864. (Gr., "a buzzing insect.") 



Short, compact species, readily known by having the thorax 

 broad at base and narrow in front, its lateral margins bent under 

 the body and divided by a deep groove or pit for the reception of the 

 antennal club ; the mouth parts except labrum covered by the pro- 

 jecting prostemum, and surface covered by small, variegated scales 

 instead of the usual hairy pubeseeace. They are the ^A•orst of 

 museum pests, being especially destrnetive to dried insects. Five 

 or six species are known from the United States, four of which 

 occur in Indiana.
