1911] Banuti and McDiinnough — Olene Species 159 



assuming that Doctor Dyar is correct in stating that a black 

 hair-pencil accompanies joint twelve, a fact not mentioned by 

 Beutenmuller. These produced two males and one female of what 

 we consider to agree most closely with var. interposita Dyar. This 

 would support Doctor Dyar's theory that manto, interposita and 

 montana are but three forms of one species. The ground color of 

 the female is much lighter brown than in the males, and the close- 

 ness of the t. a. and t. p. lines on inner margin is apparently 

 characteristic. We refer to the plate for further details. 



In conclusion we venture to describe as a new species a form 

 from British Columbia, which is totally unlike anything we know, 

 but which may possibly be but an extreme melanic race. 



Olene styx n. sp. 



Primaries deep black-brown; all traces of maculation practically lost with the 

 exception of an obscure black basal dash, a large reniform very faintly outlined in 

 whitish and a small white spot above anal angle. Secondaries deep smoky, in the 

 female with outer margin concave below apex, in the male well rounded. Beneath 

 smoky with faint traces of discal spots on both wings. Expanse, male, 32 mm.; 

 female, 36 mm. 



Habitat, Duncans, B. C. (Hanham). 1 male, 1 female. Types Coll. Barnes. 



DANIEL WILLIAM COQUILLETT. 



In the death of Mr. Coquillett on July 8th., entomology has suffered a severe 

 loss, wh'ch is a deep personal one to a host of workers who have had the good 

 fortune to know this accomplished student of Diptera. 



He was born near Woodstock, Illinois, in 1856, and twenty-four years later 

 began his entomological career with some work on larva; of Lepidoptera, published 

 in the tenth report of Prof. Cyrus Thomas, who next year make him assistant to 

 the State Entomologist of Illinois. Soon, on account of ill health, he went to 

 Los Angeles, California, where he engaged in entomological work for the U. S. 

 Department of Agriculture, discovering the feasibility of using hydrocyanic acid 

 gas for orchard fumigation, and doing other valuable work in rearing imported 

 scale-insect parasites. In 1896 he was made Honorary Custodian of Diptera in 

 the U. S. National Museum, where he continued to study the taxonomy of Diptera 

 until shortly before his death, publishing a long series of valuable papers. 



Mr. Coquillett was one of the most kindly and patient of men, rare attributes 

 which will be cherished in the memory of his many friends.
