ON THE GENUS IIELOTA. 100 



distinct by its costate elytra and by the oblique callosity 

 between the 3rd and 6th striae, just before the black api- 

 cal half, which characters I think cannot be of sexual value. 



As to the coloration it differs from africana (according 

 to the description and figure) in having the black elytral 

 spot between the 3rd and 4th striae more elongate and the 

 line of demarkation between the fulvous and black colour 

 very irregular, while it is nearly straight in the figure of 

 africana. Moreover the legs are black or dark pitchy with 

 a very irregular fulvous ring at the base of the femora. 



The head, thorax and scutellum correspond pretty well 

 with the description of africana; the fulvous sides of the 

 thorax, however, are not finely but very coarsely punc- 

 tured , leaving free an elongate raised spot. The elytra 

 are, as in africana, half as long again as the head and 

 prothorax together but proportionately narrower and slightly 

 tapering towards and conjointly rounded at the apex; they 

 are somewhat dehiscent at the suture , and the apical mar- 

 gin is minutely bisinuate in each elytron. The interstices 

 are alternately costate; the first (sutural) and second costae, 

 however , become flat towards the base, and the second and 

 fifth ouly join the apical margin ; the third costa is some- 

 what shorter than the fourth , and the fifth does not reach 

 the basal margin ; the punctures of the striae become lar- 

 ger the more they approach the lateral margins. Between 

 the 3rd and 6th striae, just before the black apical half, 

 an oblique callosity of a somewhat paler colour is present. 

 The anterior tibiae are curved, without compressed dilata- 

 tion at the apex ; the posterior femora rather slender and 

 slightly curved. The first ventral segment is shallowly im- 

 pressed along the middle ; the fifth broadly truncate and 

 provided with a large but shallow semicircular impression 

 which is neither punctate nor tomentose. — Length 15 mm. 



Hab. East Africa: Zanzibar. — Of this very interesting 

 species three specimens have been sent to the Berlin Mu- 

 seum by Mr. C. W. Schmidt, and of these Mr. Kolbe has 

 been good enough to let the Leyden Museum have one.
