32 PROCEEDINGS OF THE NATIONAL MUSEUM vol. i05 



Specimens examined: 8 males and 4 females, Christian Valley, 

 Antigua, B. W. I., August 1943, Fennah (subspecific holotype male, 

 allotype female, USNM 62012) ; 9 males and 3 females from Nevis, 

 B. W. I., Jan. 16, 1942, Fennah; 2 males and 2 nymphs, St. Kitts, 

 B. W. I., Jan. 23, 1942, Fennah; 1 male and 1 female from forest in the 

 Central Hills, Montserrat, B. W. I., May 21, 1941, Fennah (marked 

 as in the Nevis subspecies) ; 1 female. Constitution Hill, Christiansted, 

 St. Croix, Virgin Islands, April 1936, H. A. Beatty. 



The material from Nevis is generally similar to that from Antigua, 

 but differs in that the mesonotal carinae and lateral areas together 

 with two small spots at the hind margin of the disc are pallid, not 

 uniformly infuscate; also, the areas between the pustules on the base 

 of the frons are slightly infumed, so that in the basal part of the frons 

 the pustules are plainly visible. 



The specimen from St. Croix is smaller than the Antiguan specimens 

 and the markings are bolder, but otherwise is very close to them in 

 general appearance. 



Colpoptera maculifrons grenadana, new subspecies 



Figure l,f,j,i 



Coloring very similar to Antiguan population of C. maculifrons 

 angustior, new subspecies. Tegmina with apical margin straight or 

 very shallowly sinuate, anal angle obtusely rounded; angle formed 

 by projecting apical and sutural margins of membrane slightly obtuse. 



Specimens examined: 2 males, 10 females, and 7 nymphs from 

 Mardi Gras, Grenada, Oct. 20, 1943, Fennah (subspecific holotype 

 male, allotype female, USNM 62013). 



This population is undoubtedly nearest to C. maculifrons dominicana, 

 new subspecies, but the shape of the apical margin of the tegmina creates 

 a superficial resemblance to C. maculifrons angustior. The most 

 obvious difference lies in the shape of the anal angle of the tegmina; 

 in the Grenadan subspecies this is definitely obtuse, whereas in C. 

 maculifrons angustior it is slightly acute. In the aedeagus the latero- 

 dorsal processes are rather longer than in the Leeward Island subspecies. 



The nymphs of C. maculifrons are, for an issid, most unusual in 

 their coloration. They are piu-e white, with the apex and base of 

 the frons piceous; a broad, yellowish brown band extends from behind 

 the eyes along the sides of the body to the apex of the abdomen, its 

 inner margin being dark brown. This band, when overlaid with vv'ax, 

 appears dark reddish mauve. As in other nymphs of this genus, 

 a long tuft of stiff, porrect bristles of wax is developed on the ceriferous 

 plates at the apex of the abdomen. Like the adults, the nymphs feed 

 on the unhardened apical stems of dicotyledonous woody perennials, 

 but sometimes also feed below leaves on the midrib.
