SUBFAMILY VII. RHAPHIDOPIIORIXJE. 633 



The known range of C. <jr<tcili/>cx, as above recogni/ed, there- 

 fore extends from central Ontario and southern New England 

 west to Manitoba, Minnesota, Nebraska and Colorado, and south 

 and southwest to Georgia, Mississippi and Chihuahua, Mcx. 

 While the size, color and armature of the hind femora vary greatly 

 over this large range, the prolonged truncate last dorsal and form 

 of subgenital of male, and the form and arrangement of teeth of 

 ovipositor remain almost constant and furnish characters of easy 

 recognition. 



Walker states that in central Ontario his C. paUidijies is the 

 most common species of the genus, usually occnring under chunks 

 and small logs in woods, or in rotten sodden logs, from two to 

 seven being usually found together. A few pass the winter in the 

 nymph stage though most of them reach maturity in July from 

 eggs hatched in spring. 



In Connecticut gracilipes has been taken by Walden in cellars 

 and under bark of trees. Smith (1910, 190) records it from two 

 points in New Jersey where it was taken in dark cellars and 

 barns, under stones and in hollow trees. In Maryland and Vir- 

 ginia Davis has trapped numerous specimens in molasses jars. 



301a. CEUTHOPHILUS GRACILIPES HERDS Scuclder, 1894, 54. 



Size, form and color much as in gracilipes. Hind femora proportion- 

 ally much more slender, being 25x4 mm. in greatest dimensions as against 

 23.5x5.5 in gracilipes of the same size; the spines of their lower outer mar- 

 gin more equal in size and more evenly spaced. Supra-anal plate very 

 different in form, being fan-shaped, twice as broad as long with the con- 

 cavity extending across its full width; its hind margin much broader than 

 in gracilipes, subtruncate or broadly rounded. Ovipositor proportionally 

 longer and more slender, the teeth of inner valves more aculeate, less broad 

 at base and nearly equidistant one from another; terminal hook more slen- 

 der, subcylindrical, obtuse at tip, feebly decurved. Length of body, $, 

 23.5, $,21; of antennae, $, 85, 5, 92; of pronotum, $, 6.3, 5, 7.2; of fore 

 femora, $, 11.5, 9, 12; of hind femora, $ and 9, 25; of hind tibia?, 25.5 

 26; of ovipositor, 15 mm. 



After examining the types of heros at Cambridge and the 

 paratype at Philadelphia, I cannot agree with R. & H. in making- 

 it an absolute synonym of gracilipes. The differences between 

 the two are very evident and are set forth in the key and above 

 description- Scudder's types of Jicms were taken in North Caro- 

 lina by Morrison, over 200 having been found in one old hollow 

 tree. It has been recorded elsewhere only from Ohio, but the 

 specimens so recorded are gracilipes.
