23. Orphula mexicana Walk. 



Other specimens from the same locality as the preceding 

 are referable to Walker's Stenobothy'iis mexicamis, and should 

 therefore be placed in the genus Orphula, as stated above. 



24. Amblytropidia ferruginosa Slal. (?) 



I refer three specimens collected at Greytown to this spe- 

 cies with some doubt. They may be another, and even 

 Tindescribed, species. 



25. SCYLLINA VIATORIA SaUSS. 



A single specimen of this locust was taken along the line 

 of the canal near Greytown. It is an insect that is very com- 

 mon in various parts of Mexico, and sometimes even suffi- 

 ciently numerous to become a pest. 



26. HeLIASTUS VENEZUELA Saiiss. (PI. III., Fig. 4.) 

 The collection made in the vicinity of Gre3tow^n contains 



several specimens of this insect. As the name implies, it is a 

 South American species, but the present material would indi- 

 cate that it also reaches far into North America. 



27. Tropidonotus rosulentus Stal. (PI. III., Fig. 5.) 



This is another South American locust that also occurs in 

 North America. Several specimens are found among the 

 material from Greytown. 



28. T^NioPODA (r)^sp. 



Tw^o rather young individuals of some large, undetermined 

 species of locust are referred, with some hesitation, to this 

 genus. They were taken along the line of the canal near 

 Greytown. 



29. Leptysma obscura Thiinh. 



A single specimen obtained in miscellaneous collecting is 

 placed here. I do not find any locality given. ^ The species 

 is described as occurring in tropical America. 



1 Undoubtedly from Nicaragua, and probably from Greytown. B. S.
