140 HEMIPTER A-HOMOPTERA. 
Three females from Xucumanatlan and a male from Omilteme. One of the female 
specimens is almost entirely testaceous, but this is, apparently, due to its not being 
quite mature. 
We figure a male from Omilteme and a female from Xucumanatlan. 
ATYMNA. 
Atymna, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 554. 
This genus is very closely allied to Cyrtolobus, and perhaps ought not to be separated 
from it. It bears just the same analogy to the last-named genus that Amastris bears 
to Vanduzea. 
1. Atymna castanez. 
Smilia castanee, Fitch, Third Report on the Noxious, Beneficial, and other Insects of the State of 
N. York, p. 152 (1856) ’. 
Atymna castanee, Stal, Ofv. Kongl. Vet.-Ak. Forh. 1867, p. 555”. 
| Hab. NortaH America, New York }.—Mexico, Pinos Altos in Chihuahua (Buchan- 
Hepburn). 
One discoloured female specimen from Chihuahua. This has been compared by 
Dr. Goding with a typical example of Smilia castanee, Fitch, and he informs me that 
it only differs in having a smoky band at the apex of the tegmina, a character in which 
certain allied species are somewhat variable. 
CYRTOLOBUS. 
Cyrtosia, Fitch, Fourth Ann. Report of the State Cab. of Nat. Hist. no. 30, p. 49 (1851) (nec 
Perris, 1839). 
Cyriolobus, Goding, Trans. Am. Ent. Soc. xix. p. 257 (1892). 
This genus, as well as Atymna, belongs to the group which has the apical area of the 
wings stylate, and not sessile as in Zelamona ; itis closely allied to Smilia and Antianthe. 
The tegmina have two discoidal areas, as in Antianthe, in Smilia one only is present. 
The differences between some of the species are obscure, and it is difficult to deter- 
mine with certainty, until more specimens are discovered, which of them ought to be 
regarded as having true specific value. | 
1. Cyrtolobus cristifer. (Tab. VIII. figg. 24, 24a.) 
Smilia cristifera, Stal, Stett. ent. Zeit. 1864, p. 71°. 
Cyrtosia cristifera, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 554°. 
Hab. Mexico, (coll. Signoret 4, in. Mus. Vind. Ces.). 
This is the largest species of the genus known to me, and it has the dorsum more 
strongly raised than any other. C. cristifer is not represented in our collection.
