(" Agricultural Gazette," ) Gcoscaphcus f/iganteiis is our giant cockroach, measuring 2i/o inches in length and '^Vo across the middle of the body. Like the last three it is wingless, with the large prothoracic shield overlapping the head. In colour it is bright reddish brown, crenulated and very rugose in the centre of the dorsal sur- face. In the same year (1895) that Tepper obtained this fine species, Saussure described another large roach under the name of Macropanesthia rhinoceros, forming a new genus for its reception and adding a second species which he named 31.
