Mar,, 1909.] Notes on Guatemalan Hemiptcra. 465 



through Mexico, and now to Guatemala the most southerly 

 point yet recorded. It is perhaps worthy of note that these speci- 

 mens have typical form of head and do not approach the form 

 described from Mexico as mexicana by the writer. 



Scaphoideus tesselatus n. sp. 



Size and general facies of scalaris but conspicuously tesselate ; 

 elvtral veins conspicuously marked with alternating black and 

 white spots. Female, length 5 m. m. 



Head distinctly angulate, sub-conical; vertex margins sloping, length- 

 about equal to width between eyes; front elongate, narrowing slightly to 

 clypeus. Clypeus about twice as long as broad, slightly wider at apex; 

 lorae very large reaching almost the border of the cheeks which form a 

 very narrow margin; genae very slightly sinuate; antennae very long, 

 extending almost to tip of abdomen. Pronotum strongly arcuate in 

 front; truncate behind; lateral margins very short. Costal nervures not 

 refiexed; first one opposite basal part of outer ante-apical cell, ante-apical 

 cells equal, parallel margined; apical cells sub-equal in size. 



Color: Vertex blackish with two small whitish points at extreme 

 apex; two small semi-circular spots between ocelli, behind Avhich are two 

 brownish depressed sub-triangular spots; faint median whitish line and 

 faint whitish borders at occiput against the eyes and distinct whitish 

 circles around ocelli. Face brownish; border next the vertex black, mar- 

 gined by sinuate whitish line; antennae pallid brownish at base, seta 

 darker; pronotum brown with darker fuscous on anterior border and 

 irrorate with transverse whitish spots; scutellum fulvvis at center, two 

 fuscous spots each side, basal angles and apex yellowish white. Elytra 

 golden brown with dark fuscous or blackish on the veins and at apex of 

 clavus, interrupted by conspicuous Avhite spots; three larger whitish spots 

 on clavus; two on the sutural margin; one near the base next claval 

 suture; three larger Avhitish spots on corium two corresponding with 

 transverse veinules and one on first costal cross vein. Apical veins 

 broadlv margined with smoky fuscous. 



Genitalia : Last ventral segment of female nearly twice as long as 

 the penultinate ; broadly excavate and with a broad rather blunt median 

 tooth; pygofers rather narrow, as long as ovipositor, narrowed posteriorly 

 with rather stiff short bristles arranged in two somewhat irregular series 

 each side. 



The single specimen of female was collected by Prof. J. S, 

 Hine at Los Amates, Guatemala, Feb. 18-05. While distinctly 

 belonging to the scalaris group, it is very distict- indeed from any 

 of the known species. Its handsome checkered appearance will 

 readily distinguish it. 



Chlorotettix vittata. n. sp. 



Greenish white with distinct fusco-hy aline lines on elytra. 

 Female length to tip of elytra 7 m.m., male 6.75 m.m. 



Head scarcely as broad as pronotum; vertex round in front, scarcely 

 longer at middle than next the eye; front narrowed apically; clypeus 

 widened at apex; lorae eliptical, rather narrow; genae with sinuate rnargin. 

 Pronotum concave behind; elytra sub-hyaline, veins small and indistinct. 



Color: Pallid greenish white; elytra somewhat milky with two slender 

 oblique lines on clavus parallel to claval suture on the corium. The lirst 

 and longest lying in the cell between sectors of the inner vein, second and 

 third in the adjacent cells; fourth in the outer ante-apical and apical cells.
