A NEW GENUS AND SPECIES OF COCCID FROM LORANTHUS 



(HEM.-HOM.). 



BY HAROLD MORRISON, V. S. Bureau of Entomology. 



From available literature and records, it appears that forty- 

 four species of the family Coccidae have already been recorded 

 from Loranthus, 1 and it is therefore of some interest to publish 

 the addition of not only a new species, but a new genus of this 

 family as an inhabitant of this host plant. The species in ques- 

 tion was collected by the writer, in company with Mr. G. E- 

 Bodkin, Government Economic Biologist of British Guiana, in 

 the Botanic Gardens at Georgetown, British Guiana, in Sep- 

 tember, 1918, and Mr. Bodkin kindly furnished the name for the 

 host plant. A considerable quantity of leaves of the host was 

 obtained, but not gone over until some months later, at which 

 time, through the careful work of Miss Sadie Keen, an employee 

 of the U. S. Bureau of Entomology, in picking out and mount- 

 ing the different species, it was possible to identify the following 

 list of species as occurring on the host material in addition to 

 the new species described below: Orthezia praelonga Dougl., Pro- 

 topulmnaria pyriformis (Ckll.), Coccus acuminatus (Sign.), Coccus 

 elongatus (Sign.), Coccus mangiferae (Green), Coccus viridis 

 (Green). Saissetia hemisphaerica (Targ.), Saissetia nigra (Nient.), 

 Saissetia oleae (Bern.), Pseudaonidia articulatus (Morg.). All of 

 these species were common elsewhere in the garden, and all are 

 well known to infest a wide range of host plants. 



The writer is indebted to Emily Morrison for the drawings 

 accompanying this paper and for other assistance in its prepara- 

 tion. 



1 It seems probable that most of the Coccid records from "Loranthus" 

 should be considered as records for the family Loranthaceae, since for example, 

 while many of the records are for new world species of both plants and in- 

 sects, according to Engler (Die Natnrlichen Pnanzenfamilien, etc., Pt. 3, 

 Sec. i, 1889, pp. 156-198), the genus Lnnnithns is confined to the old world 

 with very a few exceptions.
