MAMURIUS.—SAGOTYLUS. 115 
MAMURIUS. 
Mamurius, Stal, Stett. ent. Zeit. xxiii. p. 278 (1862). 
This genus principally differs from Archimerus by the produced median lobe of the 
head. Only one species is known, and that at present from Mexico alone :— 
1. Mamurius mopsus. (Tab. XII. fig. 15.) 
Mamurius mopsus, Stal, Stett. ent. Zeit. xxiii. p. 298. 142*; En. Hem. i. p. 188. 1°. 
Hab. Mexico 12, 
A typical specimen in the collection of Dr. Signoret is here figured. 
NEMATOPUS. 
Nematopus, Latreille, Régne An. v. p. 197 not. (1829) ; Laporte, Ess. Hém. p. 30 (1882); Stal, Ofv. 
Vet.-Ak. Forh. 1867, p. 539. 
Merardus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 450; Hem. Fabr. p- 48, note (186s). 
The posterior coxee are placed much closer together than in the preceding genus, 
equalling in this respect the position of the intermediate coxe. The head above is 
obtusely tuberculated near the inner margin of the eyes. 
This is a well-represented Neotropical genus; but only two species have as yet been 
received from Central America :— 
1. Nematopus lepidus. (Tab. XI. fig. 10, 9.) 
Nematopus lepidus, Stal, Stett. ent. Zeit. xxiii. p. 293. 143"; En. Hem. i. p. 141. 3”. 
Hab. Muxico!?; Guatemaa, Senahu, Panima (Champion). 
A female specimen from Guatemala is here figured. 
2. Nematopus nigro-annulatus. (Tab XII. fig. 14.) 
Nematopus nigro-annulatus, Stal, En. Hem. i. p. 141. 4’. 
Hab. Mexico!; Guatema.a, Cahabon (Champion). 
A Guatemalan specimen is here figured. 
SAGOTYLUS. 
Sagotylus, Mayr, Verh. zool.-bot. Ges. Wien, xv. p. 431 (1865) ; Reise d. Nov., Hem. p. 88 (1866)

Sagotylus is at once separated from Mematopus by the head, which is strongly
