Acanthosoma borealis Westw. in Hope Cat. i. p. 30 (1837). SASTRAGALA VARIOLOSA. (Plate LIII. fig. 3.) Acanthosoma variolosa Westw. in Hope Cat. i. p. 30 (1837). A species allied to S. binotata Dist. SPECIES OF UNCERTAIN POSITION. ? A TRICORNIS. (Plate LIII. fig. 8.) AElia atricornis Westw. in Hope Cat. i. p. 32 (1837). I do not quite see my way to generically locate this species. The antennae are in too mutilated a condition for the foundation of a new- genus, and as the species is now figured, it will be well to wait for more perfect material before deciding its classificatory position. ? NIGRIPES. Pentatoma nigripes Westw. in Hope Cat. i. p. 41 (1837). The solitary type specimen is without abdomen and lacking also half the scutellum. It is thus in too mutilated a condition for figuring or for generic identification. ? HARRISI. (Plate LIII. fig. 2.) Pentatoma harrisii Westw. in Hope Cat. i. p. 41 (1837). Westwood gives the habitat of this species as " Georgia Americas" a locality we have already seen, as in his P. pantheriiui = Antestia cruciata, he had applied to an Oriental species. I can find no trace of this species in the descriptions of North-American Pentatomidae, which are now presumably fairly complete, and am inclined to consider that the locality is also incorrect. It is therefore perhaps better to figure the species and leave the genus an open question till its locality is authenticated. ? LATERALIS. (Plate LIII. fig. 9.) Pentatoma lateralis Westw. in Hope Cat. i. p. 43 (1837). The typical and only specimen is iu a bad condition, with the rostrum wholly absent. Generic identification is thus impossible.
