Four Mexican varieties of this species are here figured. LL. pratensis is a most variable 
Species; but in all its protean forms I find the marginal spots to the cuneus and those 
at the pronotal angles to be perfectly constant. Some extreme varieties have the body 
beneath and the legs almost black. 
2. Lygus tactus, n.sp. (Tab. XXVI. fig. 9.) 
Ochraceous ; apical third of second joint, base and apex of third joint, and the whole of fourth joint of 
antenne, eyes and basal margin of head, two large anterior submarginal spots to pronotum and a subbasal 
marginal line to same, basal margin of scutellum, claval, inner, and sutural margins, a large posterior 
discal spot to corium, inner basal angle and apex of cuneus, basal angle and cellular margins of membrane, 
base and apex of rostrum, a series of obscure marginal and segmental spots to abdomen, apices of posterior 
femora and tarsal apices fuscous or black. The basal portion of pronotum, and the clavus and inner disk of 
corium is more or less infuscated, and the membrane possesses a large central and two lateral pale fuscous 
spots, 
Var. a. With the discal spot to corium reduced in size and linear in shape. 
Long. 54 millim. 
Hab. Guatemata, Cerro Zunil (Champion). 
8. Lygus tribulis, n. sp. (Tab. XXVI. fig. 10.) 
Allied to ZL. tactus, but proportionately broader and stouter, and with the following colour differences, viz. :— 
the lateral margins of the pronotum are black, the scutellum has a very broad subquadrate central spot, 
the clavus has the apical third, and the corium an irregular transverse fascia black.

A typical specimen in the Stockholm Museum is represented by fig. 2, and a varietal 
specimen in the same collection by fig. 3. 
5. Lygus championi, n. sp. 
Ochraceous ; basal margin of head, apex of second joint of antennz, basal and lateral submarginal lines to pro- 
notum, two small spots at claval apices (sometimes a small discal spot to corium and two small subapical 
spots to scutellum) black ; posterior femora more or less distinctly apically annulated with fuscous; body 
beneath and legs concolorous, tarsal apices fuscous. Third and fourth joints of antenne somewhat 
fuscous. 
Long. 63 millim.

6. Lygus vinaceus, n. sp. (Tab. XXVI. fig. 11.) 
Pale olivaceous; eyes, a basal submarginal line to pronotum, a central basal longitudinal and a transverse
