ACANTHOSOMA CRUCIATA.

i. p. 311 (1859). 
Acanthosoma borealis Westw. in Hope Cat. i. p. 30 (1837). 
SASTRAGALA VARIOLOSA. (Plate LIII. fig. 3.) 
Acanthosoma variolosa Westw. in Hope Cat. 1. p. 30 (1837). 
A species allied to S. binotata Dist. 
SPECIES OF UNCERTAIN POSITION. 
2? arricorNIs. (Plate LILI. fig. 8.) 
Atlia atricornis Westw. in Hope Cat. i. p. 32 (1837). 
I do not quite see my way to generically locate this species. The 
antenne 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 harrisit Westw. in Hope Cat. i. p. 41 (1837). 
Westwood gives the habitat of this species as ‘ Georgia 
America,” 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. 1. p. 43 (1887). 
The typical and only specimen is in a bad condition, with the 
rostrum wholly absent. Generic identification is thus impossible.
