apical marks on front and middle femora of male (these marks some- 

 times present but small in the female), sometimes a small spot on outer 

 apex of hind femur of male, apical blotches or bands on fore and mid- 

 dle tibiae (large in the male, reduced in the female), and certain abdom- 

 inal markings, pale yellow or ivory. The abdominal markings of the 

 female vary with the subspecies and are described under the subspecific 

 headings; those of the male are as follows: a large, sublateral, subapical, 

 quadrate spot on the f rst tergite, subapical transverse bands on second 

 to fifth tergites (deeply notched sublaterally) , a large median and a 

 somewhat smaller sublateral spot on sixth tergite (these sometimes 

 narrowly joined along the hind margin), and a large subcircular median 

 spot on seventh tergite, pale yellow or ivory; wings subhyahne; palpi 

 pale brown; legs fulvous, the coxae and trochanters often more or less 

 fuscous; hind tarsus and apices of tibiae sometimes infuscate; male 

 subgenital plate with a broad whitish margin, within which is a 

 blackish border extending to the median basal triangular piece, which is 

 whitish with a blackish triangular center. 



There are two subspecies, one in the West Indies and one from 

 Panama to southern Texas. They differ in the sharpness of the small 

 punctures on the head and thorax and in the color of the female 

 abdomen. Their male genitalia are identical. 



2a. Ceropales cubensis albopicta Cresson, new status 



Ceropales albopicta Cresson, 1869, Proc. Boston Sec. Nat. Hist., vol. 12, p. 378, 

 "9"=c?'. Lectotype: cT, Orizaba, Mexico (Philadelphia). 



Smaller punctures on frons, mesoscutum, and mesopleuron rather 

 weak and often not well defined. 



Hind tibia and tarsus rufous, the tarsus often somewhat infuscate; 

 abdomen of female rufous, the first tergite more or less infuscate 

 basally, usually with a small subapical dorsolateral ivory colored spot, 

 and the abdominal tergites with additional ivory subapical marks as 

 follows: irregular sublateral transverse marks on the second tergite, 

 similar but medially approximate marks on the third tergite (these are 

 often broken into a median and a sublateral pair of marks), a large 

 median and smaller sublateral transverse marks on the fourth tergite, 

 a large median semicircular mark on the fifth tergite, and a large 

 median subcircular spot covering the median part of the sixth tergite. 



This is the form identified by Fox (1892, Trans. Amer. Ent. Soc, 

 vol. 19, p. 56) as Ceropales agilis Smith, 1864. Mr. I. Yarrow has 

 compared specimens with the type of agilis in London and finds that 

 agilis is a distinct species, with some colorational differences, and large 

 coarse punctures on the frons and clypeus.
