Oue speciineu. Arizona, Mr. Ulke. Differs from the other species 

 with yellow thoi'ax by the elytra also being pale, and by its smaller 

 size.

Kansas: three specimens given me by -Mr. Ulke. This species pre- 

 cisely resembles Fh. r/entiUs Lee., {Proc. Acad., 1865, 208). except 

 that the elytra are entirely black, instead of having the suture and 

 lateral margin yellow ; the lateral black vittaj of the thorax are als(j 

 wider, leaving the reflexed marginal bead yellow. 



DIABROTICA. Chevr. 



D. blandula, elongata, pallida, capite postpectore. vittis elytrorum tribus in- 

 fuscatis ; thorace quadrato, flavo, medio transversim profunda excavato ; elytris 

 punctulatis, obsolete striatis; antennis fuscis, basi pallidis. Long. 5 mm. 



Variat, elytris pallidis, sutura paulo infuscata. 



Smoky Hill river, on the wild gourd. This species has the -jd joint 

 of the antennae much longer than the 2d, and nearly equal to the 4th, 

 differing thereby from D. loiKjlconm, to which at first sight it bears a 

 strong resemblance. 



By an error of print in the synopsis on p. 212, of the Proceedings 

 of the Academy for 1865, the 8d group of the genus to which the 

 present species belongs is stated to have the 2d and 3d joint-; of thi 

 antennte equal, while in fact the od joint is longer, as in the first group. 

 This species differs in sculpture from D. vitfata by the elytra being 

 only very faintly striate. 



The synoptic table should therefore be correctel as follows : 



A. Third joint of antennae longer than the second : 



((. Thorax not impressed; elytra no.t striate ("ironp I 



b. Thorax deeply impressed; elytra striate Group 3 



]{. Third joint of antennje equal to the second : 



a. Thorax with two faint fovete; elytra even, not striate Grouj) 2 



b. Thorax with two deep excavations; elytra carinate towards 



the sides Group } 



D. lemniscata, elongata, nigra nitida, thuraco quadrato, lateribus fortiter mar- 

 ginatis, subsinuatis, angulis omnibus subprominulis, dorso profunde biim- 

 presso ; elytris subtilissime alutaceo-granulatis, sat dense subtiliter piinctatis.
