legs as long as the following two joints together; prosternuin 

 extremely narrow. 



Hah. Salisbury, Mashonaland {G. Marshall). 



This species is very closely allied to P. pallida Jac. and P. gestroi 

 Jac, both African ; it is, however, a more robust, larger and convex 

 insect, the sides of the thorax are less rounded and the antennae 

 are shorter : from P. lactea Jac. the uniform flavous antennae 

 and much narrower thorax distinguish it. I received several 

 specimejis of it from Mr. Guy Marshall. 



Phtgasia maeginata, sp. n. 



Mavous, the head and thorax impunctate ; elytra chestnut-brown, 

 finely and closely punctured, the lateral margins flavous, nai'rovvly 

 re flexed. 



Length 4-5 millim. 



Head flavous, impunctate, the frontal tubercles small and thick, 

 carina broad and strongly raised, mandibles and palpi fulvous; 

 antennae rather robust, extending slightly beyond the middle of the 

 elytra, flavous, all the joints thickened, the third and following 

 ones of equal length, terminal joint more elongate ; thorax twice 

 as broad as long, the sides rounded and with a rather broad margin, 

 the anterior angles obtuse, the posterior ones distinct, the base 

 with a transverse sulcus bounded at the sides by a perpendicular 

 groove, the surface entirely impunctate, flavous ; scutellum flavous ; 

 elytra slightly wider at the base than the thorax, finely and closely 

 punctured, with a narrow reflexed margin, the latter, the epipleurae, 

 and the apex more or less flavous, the rest of the surface dark 

 brown ; underside and legs flavous. 



Hab. Cameroons (Conrad). 



Three specimens, which I received from Dr. Kraatz, agree in 

 every respect : the species may be known by the system of color- 

 ation, which differs from that of P. marginicollis Jac. (sub Lactica) 

 in the flavous head, elytral margin, and similarly coloured under- 

 side ; it is also of smaller size. 



Phtgasia lactea, sp. n. 



Pale testaceous, the antennae (the basal three joints excepted) 

 black ; thorax impunctate, the basal sulcus distinct ; elytra 

 extremely closely and finely punctured. 



Length 5 millim. 



Head impunctate, the eyes large, the frontal tubercles rather 

 feebly raised, interrupted at the middle, the palpi very robust ; 

 antennae black, the lower three joints flavous, all the joints rather 

 robust, the third joint very slightly longer than the fourth ; thorax 

 transverse, more than twice as broad as long, the sides with a 

 rather broad reflexed margin, rounded, the anterior angles oblique, 

 posterior ones produced into a short tooth, the surface entirely 

 impunctate, shining, the base with the usual sulcus deeply 

 impressed and bounded at the sides by an equally deep longitudinal 

 groove; elytra convex, not depressed below the base, distinctly
