genera and s])ecies oj the group of Psyllida. 465 



sparingly clothed with fine, almost erect, hairs ; 1st and 

 2nd joints short, stout ; 1st twice as stout as the 2nd, 

 and about one -half longer ; 3rd longest, one-third longer 

 than the 4th ; 4—8 almost equal in length ; 9th niore 

 than twice the length of the fusiform, black, terminal 

 one. Eyes, viewed from in front, almost hemispherical, 

 from the side obtuse, reniform. Thorax : pronotum red, 

 narrow, slightly widest at the lateral margins; meso- 

 notum red, moderately convex ; dorsulum of an irregular 

 hexagonal form ; anterior and posterior sides greatest, 

 central portion red, convex, scutellar portion red. Elytra 

 brown, coriaceous, shining, finely but irregularly wrinkled 

 transversely, elongate, narrowly rounded at the apex, 

 three times as long as broad ; nerves red ; costal margin 

 somewhat reflexed from the base ahnost to the stigma ; 

 stigma elongate, terminating a little way before the apex 

 of the radius, red, thickly interrupted transversely by 

 fine, irregular, white lines ; radius slightly curving to- 

 wards the costal margin throughout its entire length 

 until approaching its extremity, when it bends suddenly 

 round and joins the marginal nerve a little way in front 

 of the apex of the stigma ; cubitus petiole, arm and 

 inner branch of the lower furcation almost equal to each 

 other in length ; upper furcation long, narrow, a little 

 more than two-fifths the length of the elytron; upper 

 branch terminating in the apex ; lower branch curving 

 towards the dorsal margin for the greater part of its 

 length, then suddenly bending round and joining the 

 marginal nerve about in a line with the apex of the 

 radius ; lower furcation, inner branch nearly straight, 

 outer branch convex at the base, then concave to within 

 a little way of the apex ; distance between the apices of 

 the branches of the furcation, measured on the marginal 

 nerve, twice as great as that between the apices of the 

 branches of the upper furcation. Legs red. Thighs : 

 3rd pair yellowish. Abdomen above red ; anterior mar- 

 gin of 4 Qi- 5 segments black ; below yellowish. Length, 

 31- lines (Paris). 



Mr. Walker's remark, in his description, on the 

 " scarcely visible white dashes or spots" on the elytra is 

 imaginary, as they are simply caused by the light falling 

 on the uneven surface when moved to and fro.
