and renders the observation and collecting of other insects very difficult 

 because, unlike the Ephydras, these Saldas cannot be driven away. The 

 imagoes manage in course of time to get out of the way, but the ground 

 remains covered with a multitude of jumping larvas and pupae. One or 

 two other species of Salda occur among 6". interstitialis but are nmch 

 rarer, while the large S. coriacea occurred only among the sparse grass 

 growing along the sulphur creeks. A very peculiar species of Salda 

 (possibly forming a new genus) was never seen above ground, but lives 

 nearly subaquatic on the underside of stones in sulphur springs or 

 between the wet roots of the grasses growing close to the water. A 

 genus of Heteroptera which we expected to see in great numbers at the 

 lake is Corixa, but we were surprised to find only a few specimens of a 

 single species (apparently C. decolor, originally described from Clear 

 Lake, Cala.,) in the salt pools near Syracuse. It is possible, however, 

 that they become more abundant later in the season. Various other 

 Heteroptera found at the lake do not appear to be saline species, nor 

 were there any saline Homoptera observed. 



No Microlepidopterous larvae were observed on the saline flora, but 

 there are various species of Microlepidoptera feeding on these plants. 

 None of them were reared ; but it is possible that there are among them 

 species peculiar to the Salt Lake reigion. As to the Orthoptera we were 

 surprised at not finding anything that may indicate a saline species.* 

 Some species of Odonata live in the sulphur creeks and some of the 

 imagos were captured ; but the same species were also seen at Utah 

 Lake, which is fresh water. 



The Coleoptera are best represented among the maritime and saline 

 insects, and since most of our attention was devoted to this order, we 

 found about xoo species in the immediate vicinity of the Lake, not 

 counting those which were found drowned in the water, nor those which 

 plainly belong to the desert fauna, of which quite a number of species 



*0n June 25th we found at the southern shore of the lake a considerable number of 

 Anahrits simplex washed up Ijy the waves and all badly decayed. Since we were 

 unable to find a single living specimen of these gigantic crickets under stones, etc., any- 

 where near the lake we concluded that they must have bred on Antilope Island, situated 

 about nine miles from the shore where the dead specimens were seen. But since my 

 return from Utah I have read Dr. Aug. Forel's vivid account of the life-habits of the 

 North African desert cricket, Brachytrypus megacephahis, which is a nocturnal species 

 and lives on sandy soil in deep holes, which are closed up during day time by a hillet of 

 sand. Anabrits simplex has possibly similar habits, and we may, after all, have over- 

 looked its abodes in dry, sandy places close to the lake.
