forming a dense covering to the body ; the dorsals and the small spines 

 over feet orange, all others black ; head black. 



Mature Larva (after fifth moult probably). -Length i inch; color velvet- 

 black, dotted with whitish points ; under side smoky-brown ; the dorsal 

 spines yellow, with black bristles, those over feet yellow ; all others black ; 

 feet black, pro-legs brown ; head small, sub-cordate, the vertices a little 

 prominent ; dark brown ; much covered with black hairs. 



Chrysalis. — Length .6 to .65 inch. Cylindrical ; head case narrow, 

 short, compressed transversely, excavated at sides; mesonotum not pro- 

 minent, rounded, followed by a shallow depression ; abdomen stout, 

 furnished with several rows of sharp, conical, rather short tubercles, those 

 of medio-dorsal row standing on the anterior edges of the segments ; the 

 wing cases a little flaring at base, depressed in middle ; color a delicate 

 blue-gray ; of wing cases buff, more or less, but always slightly, tinted with 

 red ; whole surface much marked with black ; on wing cases a black 

 patch extends from base almost to hind margin, the nervules being orange ; 

 the hind margins are bordered by two parallel rows of serrated spots ; the 

 head case is largely black, and the mesonotum also ; the tubercles more 

 or less enclosed by black ; behind those of medio-dorsal row are four 

 small spots forming with the tubercle a triangle, and there are similar spots 

 on sides. Different chrysalids vary in respect to these black markings. 



This history of Baroni is more complete than that of any other of the 

 Californian Melitseas. The species is the most beautiful of its genus on 

 this continent, the larger part of the under surface of wings being of a 

 brilliant red-lead color. In size and in the appearance of upper surface 

 it is near to Editha Bois. 



A SUCCESSFUL MOTH-TRAP.

 which to capture the Noctuidae, but the results have been usually so
