The Venom and Poison Glands of Pseudomyrmex Pallidus (F. Smith)

In the United States. the small subfamily Pseudomyrmicinae is represented by several species which are known to sting severely. Probably the most common species in the southeastern area is Pseudomyrmex pallidus (F. Smith). As part of a program of study on ant venoms in our laboratories, this paper presents a characterization of the venom of this species, a description of its...

The Female of Bertrana Hieroglyphica Petrunkevitch (Araneae, Argiopidae)

Four species of this very interesting genus are known at the present time. Keyserling (1884) established the genus and described the first known species from a group of females from Peras, Brazil. Two other species have been described from South America by Simon (1893); one of these was from Peru and the other from Para, Brazil. Dr. Petrunkevitch was the first to describe a male...

A Description of Pocobletus Coroniger Simon (Araneae, Linyphiidae)

More than thirty years ago I began finding this species in my coIlections from localities in the Panama Canal Zone. For many years they were regarded as representatives of a new genus. During a period of work in the Museum National d'Histoire Naturelle in Paris in 958 Dr. H. W. Levi made sketches of the type specimens of Pocobletus coroniger Simon and later identified my...

Carbon Dioxide, a Releaser for Digging Behavior in Solenopsis Geminata (Hymenoptera: Formicidae)

The behavior of ants digging through sand or clay in the direction of trapped nestmates has been described by Belt (1874) and Lafleur (I940). Wilson (1958) showed that in Pogonomyrmex badius (Latreille) this behavior pattern is released by a volatile substance originating from the mandibular glands. Later, McGurk et al. (1966) identified the responsible compound as 4-methyl-3...
