112 THE CANADIAN ENTOMOLOGIST 



Abdominal tergites orange-yellow with three conspicuous brownish black 

 stripes, on the subterminal segments the entire sclerites are darkened; basal 

 sternites yellow, the others passing into brown. Ovipositor with all the valves 

 short and blunt, somewhat as in the hicornis and collar is groups of the genus. 



Habitat. — ^Colorado. 



Holotype — 9, Lawn Lake, Estes Park, altitude 11,000 feet, August 27, 

 1919, (P. W. Claassen). 



Paratopotype — 9 • 



This curious fly might well be mistaken for a male, but the specimens are 

 undoubtedly females. Somewhat similar structures are found in the collaris 

 and hicornis groups. The species is respectfully dedicated to the collector, Dr. 

 P. W. Claassen. 



SUMMARY OF WOOD'S MYRIAPODA PAPERS. 



BY HORACE GUNTHROP, 

 Washburn College, Topeka, Kansas. 



We note by Science^ that Dr. Horatio C. Wood, emeritus professor of 

 materia medica, pharmacy and general therapeutics in the Medical School of 

 the University of Pennsylvania, died January 3, last, at the age of 79. Before 

 taking up the study of medicine, he was interested in natural history, and was a 

 worker in the Academy of Natural Sciences, publishing several papers in the 

 Insecta, and nine on the closely related group Myriapoda. In these latter we 

 have by far the most extensive work done in this country on this group by any 

 individual up to his time, and these papers must rank as the foundation on 

 which all work on the Myriapoda has since been built. 



The first of these papers (1)^ was a preliminary report on the genus Scolo- 

 pendra, and describes four species as new. The next year he issued a general 

 catalogue of the Chilopoda (2) in which two new genera and twenty-nine new 

 species are included. In the following year three papers appeared, the first on 

 the Polydesmidse (3) includes the descriptions of ten new species, the second 

 one on the Julidae (4), fourteen new species, and the last (5), two new genera 

 and the same number of species. In 1865 appeared his "Myriapoda of North 

 America" (6), in which there are eighteen genera and ninety-two species listed, 

 three of the latter being classed as new. This is an extensive monograph illus- 

 trated with numerous cuts and three plates, two of which are coloured. It 

 discusses the external structure, and brings the systematic side of the subject 

 up to date, reviewing the work of all earlier writers with the notable exceptions 

 of C. L. Koch and Saussure, whose writings must have been unknown to Wood, 

 judging from omissions and the resulting synonyms. The same year he published 

 the one paper he wrote on foreign material (7), describing a new genus {Oligaspis) 

 and species (0. puncticeps) from Port Natal, and a single new species {Glomeris 

 hicolor) from Hong Kong. His work on the group closed with two short papers 

 published in 1867, the first one (8) describing four new species from Texas, and 

 the second (9), six new species from Illinois and California. He retained his 

 interest in insects for some time after this, but after 1875 cellular botany and 

 medicine filled all his time.
