1918] Coccidce of Cuba 171 



with Comstock's description and figure, (Report of the United 

 States Department of Agriculture, 1880, p. 227), with the 

 exception that the specimens have a seta upon both the ventral 

 and lateral aspects of the median pair of lobes, whereas Com- 

 stock gives one on the dorsum only. The material at hand has 

 well-developed pectinae laterad of the fifth pair of lobes and 

 these are not shown perfectly in Comstock's figure. Newstead 

 (PL XXXII, Fig. 2, Monograph of the British Coccidse), illus- 

 trates the fourth lobe as trifurcate. This is believed to be 

 an error. • 



Species of Conchaspis Ckll. 



A. Antennae of adult female with six segments C. Newsteadi Ckll. 



AA. Antennae of adult female with less than six segments. 



B. Antennae of adult female with five segments. .C. fluminensis Hemp. 

 BB. Antennae of adult with less than five segments.. 



C. Antennas of adult female with four segments, body gradually 

 narrowed caudad of thorax. 

 D. Body of adult female purplish red, scale conical with apex 



normal C. angrteci Ckll. 



1 DD. Body of adult female colorless, except the brown pygidium, 

 scale conical, apex to one side. . C. angrasci hibisci Ckll. 

 CC. Antennae of adult female with three segments, body abruptly nar- 

 rowed caudad of the thorax C. socialis Green. 



Species of Pseudischnaspis Hemp. 



A. Large dorsal gland orifices of each side in two rows running parallel with the 



pygidial margin. Club shaped paraphyses in five pairs, the first pair 



small, arising from the inner margin of the median pair of lobes, four 



large ones beyond. 



B. Circumgenital pores in four groups, anterior laterals of seven each and 



posterior laterals of eight each. Five distinct serrations and some 



indistinct ones lateral of the third pair of lobes. .P. bowreyi (Ckll). 



BB. Circumgenital pores in five groups, median two anterior laterals five and 



posterior laterals three. Three distinct serrations laterad of the 



third pair of lobes P. longissima (Ckll). 



AA. Large dorsal gland orifices of each side not arranged in two rows rurming 



parallel with the pygidial margin. Paraphyses in six pairs. 



B. A single bifurcate plate in each of the incisions, one laterad of the third 



pair of lobes and two simple plates on the pygidial margin. Tips of 



bifurcate plates recurved and points rounded. Second, fifth and 



sixth pairs of paraphyses longest. First, third and fourth pairs less 



than one-half the length of the others P. alienus (Newst). 



BB. A single bifurcate plate between the median pairs of lobes, two trifurcate 

 plates in the second and third incisions and a trifurcate plate laterad 

 of the third lobe. No plates on pygidial margin. Bifurcate and 

 trifurcate plates with points triangular and tips acute. Second and 

 fifth pairs of paraphyses longest, fourth and sixth about two-thirds 

 their length, and first and third less than one-half the length of the 

 longest P. linearis Hemp.
