2C0 TINGIDINA. 



Genus 5. — Orthostira, Fieh. 



Short, oval, reticulated ; the elytra generally abbreviated beyond the 

 large cell, but still longer than the abdomen and rounded pos- 

 teriorly ; the wings rudimentary ; when the elytra are fully 

 developed they are much longer than the abdomen, the form is 

 a longer oval, and the wings are present. 



Head broad, 4-sided ; Croivn in front with 2 short, central^ pro- 

 jecting, divergent or straight spines and one before each eye, within 

 which the antennae are inserted; Face; middle lobe rather promi- 

 nent. Antenna ; 1st joint short, thick ; 2nd ^ the length of the 1st ; 

 3rd thin, much longer than the 1st and 2nd together ; 4th subfusi- 

 form. Fyes large, prominent. Itosti'icjn thin, reaching across the 

 metasternvim, 2nd joint longest. 



Thorax. — Pronotumi short, rhomboidal ; hood small, convex, over- 

 hanging the head ; side margins projecting, with 2 or 3 rows of 

 transparent meshes ; disk with 3 keels, each with 1 row of meshes, 

 or with the side keels wanting. Elytra ; anterior margin reflexed, 

 with one or two rows of transparent meshes ; disk with a long, curved 

 lanceolate cell, the upper end pointed and turned outwards, the 

 lower end turned inwards, with a single nerve extending posteriorly 

 beyond it ; the cell-nerves strong and raised. In the undeveloped 

 form, which is that generally met with, the elytra have their inner 

 margins straight and not overlapping ; when the elytra are developed 

 fully, the portion below the cells is widened inwardly, overlapj)ing 

 each other, and the outer sides are posteriorly sinuate. Sternum; 

 the segments with parallel margins, the rostral channel but little 

 widened posteriorly, its sides raised. Legs short, thin.

Oetiiostira concinna, {Fieli.) Bouyjt Scott, Ent. Ann. 143, fig. 5 (1S63).
