LANTERNFLIES OF LESSER ANTILLES — FENNAH 29 



brown, genitalia fuscous. Tegmina hyaline, tinged dull yellow, 

 veinlets in middle area of membrane diffusely overlaid with fuscous; 

 sometimes corium anterior to Cui infuscate from basal third to nodal 

 line. Wings lightly and uniformly suffused brown except at apex of 



CU2. 



Anal segment of male long, distally narrow; anal foramen situated 

 about one-third from base; anal segment in profile evenly decurved 

 throughout, lower margin concave, not at all produced ventrad at 

 level of anal segment. Aedeagus tubular, curved upward distally, 

 a pair of long spinose processes arising ventrally near apex, directed 

 cephalad and lying close against aedeagus, shallowly sinuate in basal 

 half and cm-ved upward distally; a pair of shorter spinose processes 

 arising laterally near apex, shallowly sinuate, directed ventrocephalad. 

 Genital styles broadening distad, ventral margin very shallowly 

 convex, dorsal margin straight, ascending from base to process, de- 

 clivous distad of it, apical margin convex, dorsal process broad, 

 tapering distad, thickened on anterior face, narrow on margin, 

 abruptly bent laterocaudad at apex in a small subhorizontal lobe. 



Female with genitalia similar to those of C. meleagris, new species. 



Male, length 5.4 mm., tegmen 5.1 mm. Female, length 4.2 mm., 

 tegmen 5.5 mm. 



Specimens examined: 1 male (holotype, USNM 62015) and 1 

 female (allotype) in mountain forest, Dominica, B. W. I., June 11 to 

 July 8, 1939, Fennah. The female specimen is not so definitely 

 marked as the male, but the two are associated by the presence of the 

 vertical band down the middle of the frons. 



The occurrence of this species virtually side by side with C, meleagris 

 is remarkable, as meleagris, by reason of its exceptional female gen- 

 italia, stands apart from all other Caribbean Colpoptera. Speculation 

 about its origin, however, must await knowledge of the corresponding 

 species in Guadeloupe and Martinique, which lie to the north and 

 south, respectively, of Dominica.

Testaceous; frons with a cloud in middle of disc and at base, and 

 sublateral margin interruptedly, fuscous; clypeus basally testaceous, 

 distally f uscous-piceous ; vertex infuscate except in middle line and 

 in middle of each compartment; antennae fuscous; pronotum infus- 

 cate on anterior part of disc and behind eyes, infuscate areas maculate 

 with testaceous; mesonotum with disc (except in middle line), a 

 triangular area near each lateral angle, and a pair of wedge-shaped 

 markings just anterior to disc fuscous; abdominal tergites and ster-
