4. Salda polita Uhler. Hayden, Bulletin U. S. Geol. Surv., 

 1877, p. 441, ii. 



This peculiar and most interesting form was found by Mr. 

 Schwarz to be quite numerous on the shores of Salt Lake, where 

 he collected specimens on June 25. The types were obtained in 

 the vicinity of San Diego, CaL, from which locality it was only 

 known heretofore. The specimens from California are notable 

 for being about twice as large as those from Salt Lake. 



The exaggerated length of the antenna and thickness of the 

 apical joints is a marked feature of this species. 



5. Salda dispersa. New sp. 



Very closely related to 5. palltpes Fab., of Europe, and having the white 

 marks of the hemelytra essentially the same as in that species. The gen 

 eral form is also the same, but the pronotum is a little narrower, with the 

 lateral margins less curved, almost directly oblique. This insect varies so 

 much in the amount and distribution of the white marking of the hemely 

 tra that no satisfactory definition can be given of its ornamentation. In 

 general, however, it may be seen to have a broad black band across the 

 base of the hemelytra connecting with the continuous black clavus, and 

 thus forming the inner boundary of the large white spot behind the base 

 of each corium. Behind this spot are several others of smaller size; the 

 membrane has four pale cells, in each of which there is often a black 

 streak. The cheeks are usually white, as is also the lower part of the tylus, 

 and the inner side of the basal joint of the antennae. 



Length to tip of membrane, 3^-42 millim ; width of pronotum, 15-2 

 millim. 



A few specimens have the tibiae pale testaceous, with black 

 knees and tip, and with dark spots at variable intervals. 



Numerous specimens were secured at Salt Lake from June 13 

 to 25. Others were sent to me from various parts of Utah, and I 

 found the species to be comparatively abundant in various places 

 west of Denver, Colorado. 



6. Salda explanata. New sp. 



Subelliptical, deep dull black, but lustrous when the surface is rubbed. 

 Similar to 5". brachynota Fieb., of Europe, but the pronotum is broader 

 than in that species, and there is an absence of white marking on the basal 

 part of the costa. Head and antennae black, the latter sometimes piceous 

 at base; the rostrum piceous beyond the base, reaching to the posterior 

 coxae. Pronotum nearly lunate, not deeply but broadly sinuated, with the 

 humeral ends as wide, flat, rounded lobes, the lateral margins moderately 

 curved, prominently reflexed, with the submargin concurrently broadly 

 sulcated. Hemelytra a very little wider than the pronotum, with the 

 costa wide, and acutely reflexed, corium with two or three small groups of 

 obsolete pale specks ; membrane with the areoles pale, and each marked in 

 the middle with a black dot. Tibiae pale piceous on the middle. 



Length to tip of membrane, 4^-5 millim; width of pronotum, 2 millim.
