AEDES ALBONOTATA 853 



still broader lateral one joined behind to the whitish vestiture on lower part of 

 sides ; a row of yellowish erect forked scales on the nape ; bristles along margins 

 of eyes coarse, brown, those projecting forward on vertex golden-yellow. 



Prothoracic lobes elliptical, remote dorsally, clothed with broad fiat white 

 scales below, golden-yellow lanceolate ones above. Mesonotum black, clothed 

 with narrow, curved brownish-black scales and with four narrow, longitudinal, 

 nearly parallel lines of golden-yellow scales running from anterior margin to 

 scuteilum, the median pair slightly more approximated towards middle and 

 behind inclosing antescutellar space, second pair broadening gradually on 

 anterior half and involving anterior angles, a large marginal patch of golden- 

 yellow scales before wing insertions ; bristles over roots of wings pale yellow. 

 Scuteilum trilobate, each lobe with a small group of yellowish bristles ; vesti- 

 ture broAvnish-black, a patch of golden-yellow scales on mid lobe. Post- 

 notum elliptical, prominent, blackish, nude, vsdth a slight pruinosity. Pleurae 

 dark brown, coxae luteous, clothed with patches of flat, elliptical yellowish-white 

 scales; bristles small, pale. 



Abdomen subcylindrical, tapering posteriorly, sixth and seventh segments 

 apically expanded beneath; dorsal vestiture velvet-black, a median series of 

 small, basal, segmental yellowish spots on second to fifth segments, a series of 

 large, subquadrate lateral silvery-white patches, showing in dorsal view on 

 fourth to eighth segments ; first segment black scaled and with many fine pale 

 hairs ; venter black, segments with V-shaped yellowish-white basal bands. 



Wings moderate, hyaline ; petiole of second marginal cell about half as long- 

 as its cell, that of second posterior cell only a little shorter than its cell ; basal 

 cross-vein more than its own length from anterior cross-vein ; scales dull brown, 

 costa with blue luster, the outstanding ones long, broadly linear, denser towards 

 apex of wing, particularly on second vein. Halteres whitish, with dark knobs. 



Legs long and slender ; vestiture black, marked with white ; femora pale at 

 base and white beneath except towards tips, the anterior pair to tips; knees 

 narrowly silvery- white ; tibiae black, narrowly white at base beneath ; hind tarsi 

 with moderately broad white rings at bases of first three joints, mid and fore 

 tarsi with a white ring on first two joints only. Claw formula, 0.0-0.0-0.0. 



Length : Body about 4.5 mm. ; wing 4 mm. 



The larvse live in the water between the leaves of bromeliaceous plants; 

 imagos have been bred from larvae found in epiphytic bromeliads by C. Picado. 

 The species appears to be restricted to the elevated portions of Central America. 



Guatemala and southward to Costa Rica.

Original Description of Gymnometopa albonotata: 



Like huscTcii, the only apparent differences being the presence of a silvery dot in 

 middle of front margin of the mesonotum, and a distinct white band at base of first 

 two joints of the front and middle tarsi and of each joint in the palpi of the male; 

 the broad apices of the palpi of the female are white-scaled. 



San Francisco Mts., Santo Domingo, West Indies. Five males and three females 

 collected by Mr. A. Busck. 



Type. No. 8297, U. S. National Museum. 



Dr. Dyar informs me that the larva is readily separable from that of husckii.
