1897.] PHTTOPHAGOUS COLEOPTERA. OF APBICA. 575 



margin, both abbreviated behind, but the sublateral stripe ex- 

 tending to the base ; head and thorax fulvous. 



Var. h. The head and thorax black ; the elytra with a black 

 sutural stripe, widened into a square-shaped spot below the middle, 

 the sides and apex Ukewise narrowly black. 



Var. c. Elytra marked like var. 6, but the sutural stripe con- 

 nected by a transverse band below the middle with the lateral 

 sti'ipe. 



Var. d. Head black, the base fulvous ; thorax fulvous, elytra 



entirely black. 



Var. e. Head and thorax fulvous ; elytra black, the apex fulvous. 



There are, besides these forms, still others in which the elytra 

 are black with a fulvous spot at the middle and another at the 

 apex ; this latter variety seems identical with Momlepta elegans, 

 Alld., but the author gives the head, thorax, and underside as 

 fulvous. In all the above forms the underside is black, as well as 

 the four posterior femora ; the anterior legs in nearly all are 

 fulvous, but sometimes the posterior tibiae and tarsi are black as 

 well ; the elytral epipleuras are continued below the middle. 



PlATTXANTHA (?) ABDOMINALIS, n. Sp. 



Below black, above testaceous, the terminal joints of the 

 antenna;, the apex of the tibise, and the tarsi black ; thorax scarcely 

 perceptibly, elytra very finely and closely punctured ; last abdo- 

 minal segment liavous. 



Length 2|-3 lines. 



Of elongate parallel shape ; the head impunctate, the frontal 

 elevations strongly raised, trigonate ; clypeus triangular, in shape 

 of a transverse ridge ; labrum and palpi tlavous ; antenna; slender, 

 extending to two-thirds the length of the elytra, black, the lower 

 four joints Ha\ ous, basal joint slightly curved, second very short, 

 third' slightly shorter than the fourth joint, the rest nearly equal 

 in length ; thorax subquadrate, scarcely one-half broader than 

 long, the sides straight, slightly narrowed at the base, the angles 

 in shape of a small tubercle, the anterior ones obhque and pro- 

 duced outwards, the surface rather depressed, extremely minutely 

 and closely punctured, testaceous ; elytra wider at the base than 

 the thorax, with a depression bounding the shoulders within, the 

 surface as closely and scarcely more strongly punctm-ed than the 

 thorax, their epipleurae broad and extending beyond the middle; 

 legs fulvous ; the tibiae unarmed, their apex black as well as the 

 tarsi, their first joint as long as the following two joints together ; 

 breast and abdomen black, the last segment flavous ; anterior 

 coxal cavities closed. 



Nab. Mashonaland (G. Marshall). 



Of the three specimens obtained, one has the breast black only 



and the legs are entirely fulvous : this specimen is a male ; it differs 



in no other way from the others except being rather smaller. The 



species is one of the few in which the thorax shows no sign of a 



depression.
