LANTERNFLIES OF LESSER ANTILLES — FENNAH 31 



near base; distal two-thirds of corium and marginal area of clavus 

 dark fuscous, membrane brown. Wings suffused with brown. 



Anal segment of male narrow, moderately long, slightly declivous 

 distad of anal foramen, which is situated about one-third from base 

 and slightly decurved at tip. Aedeagus tubular, weakly curved up- 

 ward distally, an unequally bifurcate process arising laterally close to 

 apex, directed cephalad, the shorter limb above the longer; a pair of 

 stout spinose processes arising ventrally in apical quarter, each process 

 directed cephalad, lying close to aedeagus, and curved dorsad at its 

 tip; processes of equal length or one process longer than the other, the 

 longer sometimes on left, sometimes on right. Genital styles broadly 

 rounded-triangular, in profile with ventral and dorsal margins straight, 

 apical margin deeply rounded, dorsal process vertical, porrect, distally 

 attenuated, dilated into a small lobe at apex. 



Anal segment of female long, decurved distad of anal foramen, 

 which is situated one-third from base. Third valvulae broadly tri- 

 angular with distal margin unpigmented, slightly tumid. Pregenital 

 sternite strongl}^ produced ventrocaudad, produced portion in ante- 

 ro ventral view almost semicircularly rounded. 



Male, length 5.2 mm., tegmen 6.5 mm. Female, length 5.0 mm., 

 tegmen 6.8 mm. 



Specimens examined: 17 males, 19 females, and 8 nymphs. Ridge- 

 field, Dominica, B. W. I., July 18, 1940, Fennah (subspecific holotj^e 

 male, allotype female, USNM 62011). 



This subspecies is distinguished from the typical subspecies (of 

 which the holotype is figured for comparison) in the shape of the frons 

 and of the apical margin of the tegmina, as well as in tegminal propor- 

 tions. There is excellent agreement in the forms of both the male 

 and female genitalia between the present subspecies and the tj^^ical 

 subspecies, and it is on this account that the writer feels compelled to 

 assess the differences as being of subspecific value. 



Colpoptera maculifrons angustior, new subspecies 



Figure IJ-h 



Closely similar to typical subspecies in size, shape of head and of 

 tegmina, and in shape of male and female genitalia. 



Frons uniformly pale testaceous or stramineous with a moderately 

 broad transverse band along basal margin piceous; color of body 

 otherwise as in typical subspecies. Tegmina brown, subopaque, 

 longitudinal veins of corium concolorous or slightly darker than ground 

 color, transverse veinlets concolorous with ground; membrane sepia 

 brown, or a little lighter, with venation pale.
