Sphecodogastra texana Cresson; Cockerell, det. October 7. 



On aster along roadsides. Described from Texas. Taken in 

 Pierce county, Wisconsin, by Graenicher. 



Megachilc mcndica? Cresson. July 11. 



Taken on sand-plain of Matanzas Lake beach. One specimen 

 only. Hart took two other species of this genus in the sand region. 

 The Megachilidac are known as the leaf-cutting bees. Their cells 

 are constructed of parts of leaves. They are solitary in habit. 



Triepeoliis pectoralis Rob.; Robertson, det. October 5. 



On aster flowers along roadsides. A member of the family No- 

 madidae, which are parasites, or guests, in the nests of other bees. 



Melissodes sp. (undetermined). October 5. 



On aster flowers along roadside. Hart took three other species 

 of the genus in the sand regions. A member of the family Bnceridae, 

 which are long-tongued solitary bees, feeding upon honey and pollen. 



Melissodes aurigenia Cresson. October 5. 



On aster flowers with the preceding species. 



Bomhiis virginicus Oliv. October 5. 



On flowers of aster particularly. A very common and generally 

 distributed bumblebee. Social in habits. The nests are made in 

 cavities in the ground. The fertilized female hibernates, starting a 

 new colony in early summer. Hart took three other common species 

 of this genus in the sand region. 



Boinbias auric in its Robertson. July 6. 



One large specimen, taken from a burrow in bunch-grass. Hart 

 does not record this species from the sand. 



Apis viellifera Linn. 



The honey-bee is of rather frequent occurrence in the sand 

 prairie. 



AMPHIBIA 



Amhlystonia tigriiium Green. April 4. 



One specimen, taken under a log at the edge of a bunch-grass 

 field, southeast of Havana. Only the fore part of the body was at 

 first to be seen, the rest being sunk into the burrow. The soil was 

 not pure sand, the roots of the grass and the decay of the log having 

 made an approximation to sandy loam. A swampy depression about 

 100 feet away probably afforded a breeding place. 



This salamander is widely distributed, but is very scarce in the 

 sand region, principally because of the lack of permanent pools.
