The sports of this species represent about four ill-defined 

 types, with their intergrades. 



(1.) R. repanda, typical (we have it from Jamaica) ; repre- 

 sented also in the Museum series by R. latipes ! from Madagascar, 

 the Congo, Aden, Sao Paulo, and St. Domingo {R. per suhtilis). 



(2.) R. suhtilis, Walker, = indentata, Harvey, a dark variety, 

 from Eodriguez, S. Africa, the Congo, Abyssinia, Aden, Eio 

 Janeiro, Goya, Surinam, Para, Santarem, St. Domingo, Vene- 

 zuela, Jamaica, Chontales, and the United States. 



(3.) A variety intermediate between 1 and 2 = i^. conveniens. 

 Walk., from the Congo, Sierra Leone {R. detersa), Aden, Eio 

 Janeiro, Sao Paulo, Surinam, St. Domingo {R. exscindens), 

 Honduras {Baratlia acuta), and East Florida {E. disseverans). 



(4.) Lastly, a reddish variety, rather more distinct than the 

 other three, though linked by intermediate grades to (2), from 

 Honduras = R. mensuralis ,- we have this also from the Congo, 

 Aden, Espiritu Santo, St. Domingo, and Trinidad. 



All the four types, therefore, with their intergrades, occur 

 constantly together, and there can be very little doubt that they 

 represent one widely-distributed, abundant, and variable species. 

 It is, of course, very probable that the above synonymy will have 

 to be added to when other named forms (at present unknown to 

 me) come to hand.

ABERRATIONS IN THE STRUCTURE OF APPENDAGES 

 IN THE COLEOPTERA. 



By T. H. Garbowski, Ph.D., J. U. C. 



Although the Arthropoda generally provide an immense 

 amount of material to the student of Teratology, nothing is 

 more interesting than the occasional instances of abnormal 

 limb-development. In the following note I have described two 

 interesting cases, the first of which — a male of Lucarius ccrvus 

 var. capreolus — shows a hypertrophical multiplication of the 

 antennas ; the second is an instance of atrophy in the right hind 

 foot of Hygrocarahus variolosus.
