Var. ¢. 
Scutello apice macula pallida notato. 
Var. d. | | 
Nigricans ; plaga laterali ante medium indeterminata maculaque apicali scutelli, coxis, trochanteribus, maculis 
marginalibus abdominis discoque ventris griseo-flavescentibus, hoc nigro consperso. 
The specimen figured is the type from Mexico, in the collection of Dr. Signoret; a 
second specimen examined, from the State Museum, Stockholm, is much darker in 
colour and has a small oblong pale space at apex of scutellum, agreeing with var. ¢. | 
SYMPHYLUS. 
Symphylus, Dallas, List Hem. i. p. 87 (1851); Stal, Ofv. Vet.-Ak. Férh. 1867, p. 495. 
This genus probably extends throughout the Neotropical Region ; it is also common 
to the Antillean fauna. It comprises a number of variable forms which cluster round 
each of its species. As a rule, in separating the species of this difficult genus, size and 
shape are of the greatest value. The variation seems to run from simple punctuation 
to the formation of the punctures into curved and oblique fascie. 
The small triangular and anteriorly pointed head, together with the shortness and 
curvature of the odoriferous orifice, sufficiently distinguish this from the préceding 
genus.

The specimens figured are two varieties of this species from Guatemala. Fig. 13 
resembles in general appearance Symphylus peeilus, Dall., var., and Homemus proteus, 
var., Stal. | 
2. Symphylus plagiatus. (Tab. II. fig. 7.)

Hab. Mexico, Oaxaca!; GuaremaLa, Zapote (Champion).—N. Braziu 2, Santarem 1. 
The specimen figured is from Guatemala, and has the pronotal and scutellar markings 
more strongly developed than in the type. 
3. Symphylus modestus, n. sp. (Tab. II. fig. 8.) 
Above testaceous, thickly punctured with reddish brown, with an obscure pale central line extending through 
head, pronotum, and scutellum. Eyes somewhat pitchy; ocelli red; base of the head somewhat paler 
and impunctate. Antenne with the basal joint pale luteous ; second joint slightly longer than the third. 
Apical third of tho scutellum with the punctures much finer and more obscure. Body beneath pale
