PROCEEDINGS ENTOMOLOGICAL SOCIETY 



Antennae long, basal joint more than twice the length of the second, third 



joint slender and four times as long as the apical joint. 



Pronotum narrowing anteriorly, finely punctured, at the disk feebly 



convex and the transverse depression behind very faint; humeri broadly 



thickened; the triangular posterior portion of 

 pronotum somewhat depressed, pointed at apex; 

 the three carinse feebly raised; the lateral mem- 

 branous margins of pronotum straight, not 

 rounded, anteriorly rectangular, with two and 

 three rows of small areoles; hood small with rows 

 of minute cells, a little depressed at the sides, 

 in front nearly triangular, behind obtusely 

 rounded, at top a sharp carina with its apex pro- 

 jecting nearly in an upright position. 



Elytra narrow and long, the sides feebly 

 rounded, apical part obtusely shaped, discoidal 

 area reticulate, long, fusiform, extending as far 

 as the apex of abdomen, bounded by two promi- 

 nent longitudinal nervures, a blackish narrow 

 str'eak passes obliquely over the discoidal area 

 in the direction of the outer nervure without 

 touching the same; the subcostal margins very 

 narrow, biseriate throughout; costal margins 

 hardly broader than the discoidal area, irregu- 

 larly netted, the cells rather small; some cross- 

 nervures at the sutural area infuscated. The 

 lateral expanded margins of pronotum and the 

 head yellowish; surface of the thorax with the 



triangular prolongation somewhat greenish-gray; abdomen light brown. 

 Length, 3.2 mm.; width across the widest part of elytra, 1.2 mm. 



FIG. 1. Leptodictya 

 pinna Heidemann. 



Described from a single male specimen. Wistar, Indian Terri- 

 tory, July 3 (H. S. Barber). 



Type: No. 15326, U. S. National Museum. 



This species resembles in general appearance the Mexican species 

 Leptodictya tabida H. Schaeffer. It has the same straight, mem- 

 branous, lateral margins and the three linear carinae of the pro- 

 notum; but otherwise it is quite different in beitig distinctly 

 narrower across the elytra and the pronotal lateral margins are 

 more opaque, the cells somewhat smaller and the veins less promi- 

 nent; besides, the spines in front of head do not project beyond 

 the second antenna! 'joint. The young brood and foodplant are 

 still unknown.
