Eubule SCUtellata Westw., Hope's Catal. Hemipt., pt. 2, p. 7. 



A small specimen from west of the Huallaja River in Peru. This 

 species mimics the form of some of the Mexican Archimerids, in the 

 lunate form and in the prominent angles of the pronotum ; but the 

 shape of the head with its excavated front, and the stout antennae 

 and short rostrum abundantly distinguish it. 



Nematopus vicinus Dallas, Brit. Mus. Cat., n, p. 425,No. 9. 



One male, from the region west of the Huallaja River in Peru. 

 It differs in no important respect from specimens collected near Para, 

 and in other sections of the region of the lower Amazons River. 



Pthia lunata Fabr., Mantissa Insect., n, p. 289, No. 107. 



Collected in the vicinity of the Huallaja River in Peru. The 

 specimen is of the usual type common to Brazil, Central America, 

 Mexico, and the West Indies. 



Leptoglossus vexillatus Stal, Ofversigt Yet. Akad. Forandl., 

 1855, p. 185. 



Two specimens from west of the Huallaja River in Peru. A 

 sufficient number of specimens to show the range of variation may 

 prove this to be a form of L. zonatus Dallas. 



PYRRHOCORID.E. 



Dysdercus ruficeps Perty, Delectus An. Artie. Brazil., p. 172, 

 tab. 34, fig. 7. 



One specimen from the region west of the Huallaja River in 

 Peru. This is the commonest and one of the most widely distributed 

 of the South American Pyrrhocorids. It extends from the "West 

 Coast through Venezuela, New Granada, Guiana, the Amazons 

 Basin and thence southwards to beyond Rio de Janeiro. 



MONONYCHID.E. 



Mononyx amplicollis Stal, Ofversigt Vet. Akad. ForhandL, 

 1854, p. 239, 1. 



One large specimen from near the Huallaja River in Peru. The 

 great width of the pronotum makes this species appear very singular 

 and erratic. It would be interesting to know the conditions of local- 

 ity in which this insect lives. The breadth of the pronotum and its
