Family LYG.EID.E. 



LYG.EUS, Fab. 



1. L. turcicus. 



Lyga'HS turcicus, Fab., Syst. Rhyng. 118, No. 61. 



Lygceus (Graptolonms) turcicus, Stal, Hemipt. Fab. i, 73, No. 10. 



Inhabits Texas, Indian Territory, Illinois, Missouri, and the Atlantic 

 and Gulf regions throughout. 



2. L. recUvatus. 



Lygceus recUvatus, Say, Jouru. Acad. Pliila. iv, 321, No. 1; Complete Writings, 



ii, 24.5. 

 Lygceus (Graptolomus) recJivatus, Stal, Ennmeratio Hemipt. iii, 107. 



Inhabits Colorado, Texas, California, Arizona, New Mexico, Kansas? 

 Dakota, Oregon, and Washington Territory. 



This form is placed apart provisionally from L. turcicus, Fab., merely 

 because the full history of the species has not yet been elaborated. So 

 far as the evidence from the Atlantic region goes, it is merely one of the 

 forms of that species. The dusky variety, however, has not yet been 

 discovered in the eastern regions of the United States. It lives in num- 

 bers, like its congeners, upon the species oH Asclepias. 



3. L. costalis. 



Lygceus costalis, H.-Schf., Wanz. Ins. vii, 22, fig. 706. 



Lygceus (Graptolomus) costalis, Stal, Enumeratio Hemipt. iv, 107, No. 17. 



Inhabits Arizona, Texas, California, and Mexico. 



Sufficient acquaintance with the nature of this form may establish it 

 to be the form of L. turcicus dependent upon the table-lands of South- 

 western North America. 



4. L. Kalmii. 



Lygceus (Graptolomus) Kalmii, Stal, Ennmeratio Hemipt. iv, 107, No. 19. 



Inhabits California, Mexico, and Eastern North America. 



This is a variety still nearer than the preceding to L. turcicus, but 

 differing from it in the amount of black on the hemelytra, and in having 

 the membrane margined with white. It is retained here for the present 

 merely in deference to the views of Dr. Stal. 



5. L. tniculentus. 



Lygceus (Gra2}iolomus) trucuJentus, Stal, Stettiuer Ent. Zeit. xxiii, 308. 



Inhabits California. 



Oncopeltus, Stal.
