A CHECK-LIST OF AFRICAN COCCIDAE. 



BY T. D. A. COCKEREI.L, N. MEX. AGR. EXP. STATION'. 



Altliough tlie entomology of Africa is at 

 the pi-esent time receiving much attention, 

 botli here and in Europe, our knowledge 

 of the Coccidae of that continent remains 

 singularly deficient. The present list has 

 been compiled for the convenience of those 

 who maybe able to add to it; and here it 

 may be remarked that any non-entomologist 

 can collect coccids without much trouble, 

 simply by gathering infested leaves and 

 twigs and putting them in boxes or 

 envelopes. In this way important contri- 

 butions may sometimes be made hy resi- 

 dents in uaworked localities.

I think I have collected in this list the 

 whole of the definitely recorded species; 

 and yet the total is less than half that of 

 the single Island of Jamaica, where these 

 insects have been somewhat carefully 

 sought for of late.

NOTES UPON TOXONEURON. 



The proper spelling of the name is here 

 restored to the genus. Better sectional 

 characters than those afforded by colour I 

 have found to exist in the breadth of the head 

 and m the length of the ovipositor.
