their habits several specimens were kept alive, and in due time a 

 parasitic larva issued and spun up its cocoon. The host was 

 dead when discovered, but there is little doubt that in nature it 

 clasped the cocoon as is the habit of Megilla maculata, and 

 stood over it until death ensued. A few days later the perfect 

 insect appeared and, on being referred to Mr. Ashmead, was pro 

 nounced after careful comparison with Mr. Cresson's type in the 

 collection of the American Entomological Society, of Philadel 

 phia, and with the published description, to be Euphorus sculp- 

 tus, which was described by Cresson a quarter of a century ago 

 from a single specimen from Illinois. (Can. Ent., vol. IV, p. 

 227.) 



In the year 1892 Mr. Coquillett reared this same species from 

 "yellow ladybirds with six elytral black spots," imported from 

 Australia to California, as reported in Bulletin No. 30, Division 

 of Entomology (pp. 15-16). Hippodamia convergens and 

 Coccinella sanguined, common to both the western and eastern 

 sides of our continent, are also mentioned as hosts of this para 

 site. The Australian host is now identified as Coccinella re- 

 panda Muls. 



The year following, Mr. Koebele recorded the following 

 hosts : Hippodamia spuria, H. parenthesis, Coccinella ju- 

 liana, and A dalia frigida (Insect Life, vol. VI, p. 14). 



A PARASITE OF ADULT SCOLYTID^E. 



A minute chalcidid of the subfamily Entedoninae was reared 

 by the writer, June iS. 1894, from an adult of the scolytid 

 Phloeotribus frontalis Ol. and described by Mr. Ashmead 

 under the name Secodes phloeotribi (Trans. Am. Ent. Soc., 

 vol. XXIII, p. 233). What is with little doubt the same species 

 has been reared by Mr. A. D. Hopkins from the adult of 

 Pityophthorus minutissimus and by the writer from Chramesus 

 icorice. From the latter species the parasite issued through a 

 round hole that occupied nearly the entire dorsal surface of the 

 prothorax of its host. 



TACHINID PARASITES OF ADULT CHRYSOMELID^E. 



June 15 a dipterous parasitic puparium was found in a vial in 

 which was confined an adult of the flea-beetle, Disonycha xan- 

 t/iomelcena Dalm. The puparium was fresh, having just been 

 formed, as the beetle, then dead, had been noticed living the day- 

 previous. June 26 the adult fly issued, having passed 11 days 

 as pupa. 



The bred specimen was referred to Mr. Coquillett, who
