18 HEMIPTERA-HETEROPTERA. 
2. Orsilochus sticticus. (Tab. II. fig. 1) 
Pachycoris sticticus, Dall. List Hem. i. p. 84. 11°. 
Hab. Brrvisn Honpvuras 1, Rio Hondo (Blancaneauc). 
The specimen figured is from the Rio Hondo; it is darker in colour than the type in 
the British Museum, the bands of dark punctures being more developed. The species 
appears to be peculiar to Honduras. 
8. Orsilochus. scurrilis, (Tab. II. fig. 23.) 
Pachycoris scurrilis, Stal, Ofv. Vet.-Ak. Férh. 1855, p. 181, et 1856, p. 53}. 
Hab. Mexico!; Guatema.a, San Gerénimo, Vera Paz, Tocoy (Champion). 
The specimen figured is in the State Museum at Stockholm; and I am indebted to 
Prof. Lindstrém and Dr. Jacob Spangberg for affording me the opportunity of figuring 
this and other Central-American species described by the late Prof. Stal. The specimens 
received from Guatemala vary principally in the width of the subdiscal transverse fasciz 
and the size of the apical spots. 
DYSTUS. 
- Dystus, Stal, Stett. ent. Zeit. xxiii. p. 82 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 494. 
This genus was founded by Stal for the reception of the following species, which it 
at present alone contains :— 
1. Dystus puberulus. (Tab. II. fig. 2.) 
Dystus puberulus, Stal, Stett. ent. Zeit. xxiii. p. 83. 12}. 
Hab. Mexico 1. 
The type is figured, the same having been most obligingly lent for that purpose by 
Dr. Signoret, in whose collection it remains. 
TIRIDATES. 
Tiridates, Stal, Ofv. Vet.-Ak. Forh. 1867, p. 494. 
This genus contains two species, both Mexican, which we have hitherto been unable . 
to procure, and therefore have not examined the generic characters. It is allied to 
Agonosoma, according to Stal, by the following common characters :—‘‘ Segmento ven- 
trali sexto ventris retrorsum valde producto, apice rotundato vel nonnihil truncato, 
genitalia tegente; articulo secundo rostri articulis tertio et quarto ad unum longitudine 
eequali vel paullo longiore.”
