Oeiginai, Desceiption or Limatus nuBHAMn: 



Thorax ornamented with violet, golden-yellow and bronze, the golden-yellow 

 forming three patches, looking like the top of a cross. Abdomen almost black, with 

 basal lateral white triangular spots, venter creamy-white. Legs bronzy-brown, 

 unhanded. Bases of the wings pale yellowish. 



?. Head covered with flat bronzy-brown and dull ochraceous scales; sides of the 

 bead white; clypeus brown; proboscis black; palpi and antennae brown. 



Thorax with dense flat scales, very convex at the apex; prothoracic lobes clothed 

 with golden yellow flat scales and rich brown bristles; mesothorax clothed with rich 

 purple scales and with a golden yellow median line on the front half, and a lateral 

 transverse line on each side, the anterior border and sides also with golden yellow 

 scales, back portion of the mesothorax with duller purple and brown scales and a few 

 golden ones; scutellum with flat purple scales, border-bristles golden-brown, there 

 being four large ones to the median lobe and two median small ones; in front of the 

 roots of the wings is a small tuft of black bristles and a golden-brown tuft behind; 

 pleursa with silvery-white scales; scutellum with a tuft of golden-brown bristles 

 on its apical half and two rows of small fiat golden scales. 



Abdomen black with basal white lateral spots; first segment with creamy yellow 

 scales; venter creamy white, apex slightly bristly. 



Legs dark brown with bronzy reflections, bases of the legs and ventral surface of 

 the femora creamy white; ungues small, equal and simple. 



Wings with the veins covered with rather broad long dark scales, with the apices 

 either flat or convex, the former slightly asymmetrical; fork-cells long, the first 

 sub-marginal considerably longer and slightly narrower than the second posterior, 

 its base much nearer the base of the wing than that of the second posterior, its stem 

 about one-third the length of the cell; stem of the second posterior rather more than 

 two-thirds the length of the cell; supernumerary and mid cross-veins united at an 

 obtuse angle; posterior cross-vein not quite its own length behind the mid. 



Halteres mostly black, basal part of stem yellow. 



Length. — 3 to 3.5 mm. 



Habitat. — Para, Brazil (Dr. Durham). 



Observations. — Described from a series caught by Dr. Durham. It is a most 

 beautiful species with brilliant thorax, the three golden marks on the mesonotum 

 looking like the upper part of a cross. Females only have been received. They seem 

 to be intermediate between Saiethes and Trichoprosopon, but clearly come in the 

 same section as the latter owing to the metathoracic scales, but they differ from T. 

 nivipes in that the venation is of Oulex type. 



Original Descbiption of Simondella ouevieostkis: 



Ce petit moustique habite les bois; il se rencontre aux environs de Rio de Janeiro & 

 300-500 mStres d'altitude. Tr6s probablement il pond dans les petits d€p6ts d'eau 

 accumul€e a, Taisselle des bromelia ou d'autres plantes, d'od la difficult^ d'obtenir 

 ses larves. 



Le corps mesure 4 millimetres de longueur, non compris la trompe. 



T6te. — lo Trompe. Chez la male, elle a la forme d'une faucllle ou d'une serpe, 

 c'est-a.-dire qu'elle est form€e d'une tige droite qui se continue par un arc a convezltfi 

 supSrieure, cet arc est comme articulS par un coude avec la tige et pent s'inflechir sur 

 elle plus ou moins. La partle droite est couverte d'ficallles sombres et plus longue
