ANOPHELES ALBIMANUS 981 



" Los palpos del macho son casi tan largos como la probosis. El primero y 

 " segundo artlculo presenta una separacion indistinta. El tercer artfculo se dilata 

 "en forma de cono con la base hftcia la extremidad distal: El Spice del cono es 

 "ligeramente blanquecino; la base presenta un anillo bianco. El cuarto artfculo 

 " es mas corto y de forma c6nica tambi^n, su base tocando con la del anterior. De 

 "la base del cuarto artlculo sale un escobill6n de cerdas largas, muchas de las 

 " cuales son pardas hacia la punta. La extremidad distal de este articulo es blanca. 

 " El quinto articulo, pequeno y conico tambien presenta la parte ancha, proximal, 

 " oscura y la extremidad apical clara. 



" La manera de distribucion de las manchas en el ala podrS, apreciarse en el

El insecto que nos ocupa esta al parecer bien diseminada por toda la Isla. El 

 primer ejemplar que vimos lo recogio el Dr. Lazear en los Quemados, (Campamento 

 de Columbia) en Junio del presento ano; mas tarde, (Julio 6) capturamos nuestra 

 primera muestra en las faldas del Castillo del Principe, alrededores de la Habana; 

 de entonces aca el Dr. Guiteras lo obtuvo de Matanzas, el Dr. Davalos del Cerro y 

 nosotros en Pinar del Rio, habiendo recibido varies ejemplares de Bayamo, Cienfugos 

 y Santa Clara. Abunda este anopheles en las charcas que so forman en las canteras 

 abandonadas del Vedado y de Jesus del Monte, (Habana).

 labellas long, lanceolate, luteous, with a few outstanding setse. Palpi as long as

 and articulation of preceding one white, long joint black with a narrow white 

 ring at middle. Antennae filiform, the joints rather short, subequal, densely- 

 pilose, blackish ; hairs of whorls short, sparse, black ; tori small, subspherical, 

 with an apical cup-shaped excavation, black with gray pruinosity. Clypeus 

 prominent, subtriangular, blackish, pruinose, nude. Eyes well separated at 

 vertex, black. Occiput dark, clothed with erect and semi-erect elliptical and 

 truncate white scales medianly, black ones on the sides, a group of long white 

 hair-like scales projecting forward on the vertex ; a row of hairs along margins 

 of eyes. 



Prothoracic lobes small, lateral. Mesonotum elongate, narrow, grayish- 

 brown, pruinose, a pair of velvet-black spots centrally at anterior ends of a pair 

 of broad sublateral bare stripes, and another large spot before scutellum ; 

 vestiture of rather sparse, small, broadly lanceolate, curved ocherous scales and 

 with rows of short blackish bristles. Scutellum collar-like, uniform, gray- 

 pruinose, with a marginal row of black bristles and clothed with small white

 patches of black ones forming incomplete apical bands; hairs coarse and 

 abundant, particularly along lateral margins. 



Wings (plate 41, fig. 14) moderate, hyaline; petiole of second marginal cell 

 about half as long as its cell, that of second posterior cell longer than its cell ; 

 basal cross-vein distant more than its own length from anterior cross-vein ; scales
