81S ittt. W. L. DISTANT ON THE RHYNCHOTA [Nov. 20, 



ACANTHOSOMA CRUCIATA. 



Edessa cruciata Say, New Harm. Ind., Dec. 1831 ; Compl. Writ, 

 i. p. 311 (1859). 



Acanthosoma borealis Westw. in Hope Cat. i. p. 30 (1837). 



Sastbagala variolosa. (Plate LIU. fig. 3.) 

 Acanthosoma variolosa Westw. in Hope Cat. i. p. 30 (1837). 

 A species allied to 8. binotata Dist. 



Species of uncertain position. 



? ateicobnis. (Plate LIU. fig. 8.) 



yElia 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. 



? NIGEIPES. 



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. pantherina 

 = Antestia cruciata, he had applied to an Oriental species. I can 

 find no trace of this species in the descriptions of North- American 

 Pentatomidse, 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 in a bad condition, with the 

 rostrum wholly absent. Generic identification is thus impossible.
