100 MR. M. JACOBY ON NEW [Feb. 17, 



There is only a single specimen of this species before me, which 

 seems to be closely allied to C. limhellus, Manuerh., or rather to its 

 black variety, which is almost identical in its coloration ; but the 

 sculpture of the thorax in C. Ihnbatipennis is quite distinct from the 

 allied and other similarly coloured species, forming elongate confluent 

 rugosities at the sides, which will prevent the insect being mistaken 

 for any of the allied forms. 



Cryptocephalus partittjs, u. sp. (Plate XI. fig. 8.) 



Cylindrical, convex ; black ; base of antennae and the legs fulvous ; 

 anterior and lateral margins of the thorax and two spots at the base 

 yellow ; surface finely strigose ; elytra regularly punctate-striate, 

 yellow, a sutural and discoidal longitudinal band black. 



Length 1 line. 



Head flat, yellow, the extreme base and a short longitudinal central 

 band, connected with the latter, black ; antennae nearly as long as 

 the body, the five lower joints fulvous, the rest black, third and 

 fourth joints equal. Thorax rather transverse, the sides very little 

 rounded ; surface entirely covered with very fine confluent longitudinal 

 strigse, black ; the anterior and lateral margins (the former slightly 

 widened at the middle), and two large, closely-approached transverse 

 spots, placed at the middle of the base, yellow. Scutellum black. 

 Elytra strongly and regularly punctate-striate, the interior of the 

 spots black, the sutural band widened at the base and connected at 

 its end with the broader discoidal band in some specimens, but in 

 others isolated ; the latter commences at the shoulder, where it is 

 rather narrow, and after widening slightly immediately below the 

 base, continues straight towards the apex, where it is interrupted at 

 some distance from the latter ; the same band extends generally in 

 width from the fifth to the ninth row of punctures, the rest of the 

 disk of the elytra and their apices being bright yellow. Legs robust, 

 fulvous. Underside black. 



Wada toge. 



From all other nearly similarly coloured species (C boehmi, lim- 

 hellus, lateralis) the present may be at once distinguished by the 

 sculpture of the thorax, the close striae of which give the latter a 

 silk) appearance, punctuation being altogether absent. In one of 

 the specimens the yellow spots of the thorax are very small, and the 

 two black elytral bands are almost connected anteriorly by an indi- 

 stinct transverse piceous stain. 



Cryptocephalus nigrofasciatus, n. sp. 



cj . Below black ; apex of the abdomen, legs, and base of the 

 antennae flavous ; above testaceous ; thorax distinctly punctured ; 

 elytra strongly punctate-striate, each elytron with a longitudinal 

 black band, abbreviated behind. 



§ . Larger, entirely flavous or pale fulvous. 



Var. a. The elytral band very obsolete, sometim.es entirely 

 absent. 



Var. b. Elytra black, the sutural and lateral margin flavous.
