604 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [NoV. 16, 



base. Elytra rugose and irregularly wriakleJ, green, the lateral 

 margin narrowly and the apex broadly testaceous. Legs very long 

 and slender, first joint of the posterior tarsi longer than the follow- 

 ing joints together ; entire underside and legs pale testaceous. 



c? . Elytra near the apex with a short curved ridge. 



Nearly allied to D. eximia, Baly, but distinguished by the colour 

 of the underside and of the antennae. 



3Ius. Jacoby. 



78. DiABROTICA FLAVONOTATA, Sp. nOV. 



Ovate, convex. Flavous ; head and breast black ; antennae piceous, 

 the tenth joint testaceous; thorax fulvous ; elytra finely semipunc- 

 tate-striate, violaceous blue, shining, each elytron with five spots 

 (2, 2, 1) and the margin flavous. 



Length 4 lines. 



Head longer than broad, impunctate, black, with a large shallow 

 fovea between the eyes ; lower part of face partly punctate, with 

 some yellow hairs. Antennae as long as half the body, the second 

 joint about one half the size of the first, the third joint more than 

 twice the length of the second ; the three basal joints piceous, testa- 

 ceous below, the tenth joint entirely of that colour, the rest black. 

 Thorax transverse, the sides nearly straight ; suiTace very obsoletely 

 transversely grooved, very finely punctate ; scutellum fulvous. Elytra 

 widened behind, distinctly margined, finely punctured, the punctures 

 arranged in rather regular rows near the suture, violaceous blue ; a 

 narrow spot below the shoulder, a larger one near the scuteHum, two 

 round spots placed transversely at the middle, and a narrow trans- 

 verse spot near the apex flavous. Underside and legs testaceous ; 

 breast and a streak on the upper part of the femora and on the 

 anterior tibiae black ; the four posterior tibiae and the tarsi entirely 

 black, clothed, like the breast, with thick yellow pubescence. 



Allied to D. regalis, Baly, and D. angulicollis, Erichs.

79. DiABROTICA NIGROPLAGIATA, Sp. nOV. 



Oblong-ovate, widened behind. Black ; head, antennae, thorax, 

 and the femora fulvous ; elytra finely punctured ; the anterior half 

 fulvous, with four black spots, posterior half black. 



Length 4| lines. 



Head longer than broad, wedge-shaped, with a deep longitudinal 

 central groove ; the frontal tubercles very obsolete, entirely impunc- 

 tate. Antennae half the length of the body, the third joint one 

 half longer than the second, fourth and following joints longer than 

 the third ; fulvous, the apical joints slightly darker. Thorax sub- 

 quadrate, narrowed at the base, the sides at the same place flattend, 

 surface rather convex, obsoletely transversely depressed near the 

 base ; disk shining, impunctate. Elytra distinctly widened poste- 

 riorly and convex, very finely punctured, a little more strongly to- 

 wards the basal half, with some very obsolete longitudinal costae to- 

 wards the apex j the anterior fulvous portion does not quite extend
