Figure 8, A, shows the mesouotal subsegments of Antigastcr, as seen from above when depressed for flight or walking. Figure 8, B, shows the corresponding parts in the mesonotiun of £uri//07na, Decaioma anA hosoma; and Figure 8, C, those in Semiolellus. In all the three figures the coUare (when visible) .ind the mctathorax are shaded to distinguish them from the niesonotum; and in the mesonotum of all of them the pn-uscutum is lettereda, the scutum 6, thescutellum c, and the postscutellum d; the coUare (when visible) being U-ttered e. [Fig. 9 ]. veins and stigmatic branch brown. Hind Wings hyaline; veins pale bi-own. Length Q ^$— inch. Described from 3 9 taken upon herbage near Rock Island, Ills., in August and September; 2 g with the thoracic parts elevated and the body more or less rolled up, the other ? with the thoracic parts depressed and the body extended; d" unknown. Nothing but the almost exact coi-respondence of all the complicated oolorational and stractural peculiarities, found in this insect, would ever induce any entomologist, unacquainted with this most remarkable genus, to believe that these three specimens are all identically the same. Rock Island, Ills., March 22, 1869. (Fig. 10.).
