190 HEMIPTERA-HETEROPTERA. 
Nine specimens from Mexico and one from Guatemala, the latter being broader, 
darker, and more robust than the single Mexican female received. In one example 
the anterior tarsi have the second and third joints separated by a distinct suture. 
This insect closely resembles D. semicolon, Stal, the type of which is before me*; 
but it is smaller and less elongate, and has shorter legs, smaller eyes, a shorter third joint 
to the antenna, less acute anterior angles to the pronotum, and the frontal processes 
(jugee) stout to the tip. 
Subfam. SALYAVATINA. 
The only known American representative of this subfamily occurs within our limits ; 
the other five genera are confined to the tropical regions of the Old World. 
SALYAVATA. 
Salyavata, Amyot et Serville, Hist. Nat. Ins. Hémipt. p. 349 (1848) ; Stal, Hemipt. Afr. iii. p. 144 ; 
Enum. Hemipt. ii. p. 120, and iv. p. 80. 
In this genus the anterior tarsi are 2-, and the other tarsi 3-jointed ; and the antenne 
have their slender third and fourth joints fused into one, so as to appear 3-jointed. 
1. Salyavata variegata. (Tab. XI. figg. 25, 25a, 3.) 
Salyavata variegata, Amy. et Serv. loc. cit. p. 350, t. 6. fig. 6'; Stal, Enum. Hemipt. ii. p. 120’;

Hab. Nicaragua, Chontales (Janson); Panama (Boucard), Bugaba (Champion).— 
Guana, Cayenne!; N. Braziu?; Amazons, Para ?. 
We possess six specimens of this species, five of which are from Bugaba. The male 
has the first genital (ventral) segment greatly inflated, with its apical margin strongly 
bisinuate. A male from Bugaba is figured. 
Subfam. ACANTHASPIDINA. 
This subfamily of Reduviide includes a large number of conspicuous insects, most 
of which are found under bark or upon decaying timber. Some of the species of 
Conorrhinus attack man. They all emit a very foetid odour when handled. The 
Acanthaspidine are chiefly confined to the tropics. 
NALATA. 
Nalata, Stal, Rio Jan. Hemipt. p. 79 (1858) (part.) ; Hemipt. Afr. iii. p. 123; Enum. Hemipt. i. 
pp. 110, 119, and iv. p. 66. 
A well-defined genus, including several closely allied Tropical-American forms f. 
* The specimen sent to me by Dr. Aurivillius as the type is a male, and not a female, as stated by Stal. 
+t Opinus pygmeus, Walk., is a Microlestria and = plebeja, Stal.
