at the edge of a blowout in October, and a number of females were 

 dug from burrows in April. The males are found only in fall or late 

 summer. All of these were from the Devil's Hole. They hibernate in 

 their burrow^s and eggs are laid in spring. The egg-case is carried 

 about attached to the female. The burrows are vertical, about half an 

 inch in diameter, and are usually capped by a small turret, particularly 

 when located in bunch-grass. About half-way down, the burrow en- 

 larges into a fusiform chamber. Some of the burrows reached a depth 

 of twenty inches. Beetle remains were sometimes found in the cham- 

 bers. This spider is a dominant bunch-grass species. It is abundant 

 in the sand-dune region of the Great Lakes. It is reported also from 

 New Jersey, Texas, and Utah. This species has been confused with 

 L. arenicola and L. domife.v. Emerton determined the specimens as 

 L. iiiissouriensis; this in Chamberlin's revision of the genus is 

 synonymous with L- fatifera. It is cjuite abundant in the Devil's Hole 

 and is one of the dominant species. It is known from Alabama, 

 Georgia, Texas, Missouri, Kansas, Illinois (also in the Lake Michi- 

 gan region), and Utah. 



Lycosa erratica Hentz; Emerton, det. April 8, 9. 



A common and widely distributed species. It is conspicuously 

 marked with gray and black. Found running about in bunch-grass. 

 It is of a roving habit; one specimen, however, was found in the bur- 

 row of another lycosid, probably to molt, as a recently cast skin was 

 found near the top of the burrow. 



Lycosa zvrigJitii Em. ; Emerton, det. April 7. 



One specimen, dug from burrows in bunch-grass dune north of 

 Devil's Neck. This species has only recently been described (Psyche, 

 19:25-36, April, 1912), although it has long been known. It is also 

 recorded from the sandy shores of Lake Michigan and Lake Erie. 



Lycosa (Geolycosa) sp. (indeterminable). April 7. 



One specimen, resembling Lycosa fatifera, dug from burrow in 

 bunch-grass dune north of the Devil's Hole. 



Attidac, sp. (indeterminable). October 8. 



Taken on plants at the Devil's Hole. The jumping spiders run 

 jerkily and jump to and fro on the stems and leaves of plants, in 

 search of insect food. One Phidippus taken along the roadside was 

 eating a fly, perhaps Lttcilia caesar. They are very common spiders. 



Phidippus insolensf Hentz ; Peckham, det. April 4. 



One specimen, found dead inside a silken case under a cactus 

 lobe, on a bunch-grass dune near Havana. Hart records the species
