nized by its small size, shortness of antennje, and very dark color. The 

 underside of body and all median parts of upper surface, except hood, 

 apex of pronotum and three large areoles in sutural area vary from fus- 

 cous to black (the discs of areoles may be hyaline or w^hitish) and lateral 

 extensions of this pattern are found on posterior part of pronotal margin, 

 on costal area at widest part of elytra and near apex of elytra. The lateral 

 margin otherwise is clear; the veinlets stramineous. The first, second, 

 and fourth antennal joints vary from fuscous to black, the third joint and 

 the legs from stramineous to testaceous. 



The species is abundant about Washington, D. C, and occurs 

 not only upon the plant (Clitoria mariana L.) for which Mr. 

 Heidemann named it, but also on various species of Lespedeza 

 and Meihomia. Specimens have been collected from late June 

 to September. Examples of the species from Tennessee and 

 South Carolina also have been seen. Mr. Heidemann compares 

 the species to L. constricta Champion, to which indeed it is very 

 similar. If the respective illustrations can be trusted, however, 

 the species are sufficiently distinct. The pronotum of L. con- 

 stricta is longer and narrower than the same part in clitoricu and 

 the hemelytra are much more constricted beyond the discoidal 

 area and do not widen again as they do in the present species. 

 L. constricta is recorded from the Nearctic region by Van Duzee, 

 but no specimens have been seen by the writer.

Length of an average specimen (excluding antennse and spines), 2.83 

 mm. ; length of pronotum, 1.08 mm. ; width, .79 mm. ; greatest width of 

 elytra across discoidal areas, .92 mm. ; near apex, .99 mm. ; length of an- 

 tennal joints: i, .26 mm.; 2, .08 mm.; 3, 1.32 mm.; 4, .39 mm. 



Form narrowly oblong constructed at humeri and just before tip of 

 elytra. Head with three long, sharp spines from back of vertex, under 

 the median one of which are two shorter laterally converging ones arising 

 from front of vertex. Hood well developed, oblong, broadest and highest 

 in front'. Paranota well reflexed, with a single series of large squarish 

 areoles. Carinse moderately high, uniseriate ; the lateral ones viewed from 

 above, a little wavy behind. Costal area with a single series of large 

 squarish areoles from humeri to or near end of discoidal area, biseriate 

 near constriction, then again uniseriate.
