placed nearly vertical, vertex broadly grooved on the 

 middle, transversely impressed between the upper corners 

 of the eyes: the front tumid, subpentagonal, nearl}' flat 

 on the middle, the outline strongly curved when viewed 

 from the side ; the sockets of the antennae seated in a cav- 

 ity. Antenna^ long and slender, the basal joint longer 

 than the pronotum, the second longest, as long as the 

 clavus, the third not much more than half as long, the 

 fourth more slender and a little shorter than the third. 

 Rostrum slender, pale greenish, dusky at tip, reaching 

 behind the middle of venter. Pronotum wider than long, 

 paler anteriorly, the collum prominent, confined to the 

 width between the eyes, callosities oval, low, tinged with 

 reddish-brown, the posterior margin broadly curved, a 

 little uneven, with the humeral angles a little reflexed and 

 the adjoining surface indented; the surface uneven around 

 the callosities, pale pubescent near the sides, the lateral 

 margin not distinctly carinated, very slightly sinuated; 

 lower margin of pleural flaps pale, reflexed. Chest and 

 venter greenish-white, silky pubescent. Legs yellowish, 

 the femora a little dusky near the tip, with the nails black. 

 Scutellum green, a little convex, sometimes red at base, 

 with the tip acute. Corium pubescent, either entirely 

 green or bordered with red inwardly, the costal margin 

 pale yellowish-green; the clavus red or reddish-brown, 

 sometimes clear green; cuneus green, occasionally bor- 

 dered inwardly with red; membrane fuliginous with the 

 vein darker. Tergum more or less rufous. 



Length to tip of venter, 5—55^ mm. Width of prono- 

 tum, 1^4-2 mm. 



A few specimens of this beautiful form were collected 

 at San Jose del Cabo by Dr. Gustav Eisen. As the al- 

 cohol in which these specimens were placed had disin- 

 tegrated them for the most part, the study of their legs 

 and antennee had to be derived from detached members.
