mately equal to one-third basal width, lateral margins weakly con- 

 cave and convergent to broadly rounded median portion, except 

 in a very small area mesad where a small rounded production oc- 

 curs, the surface of this concave, the entire distal margin well sup- 

 plied with elongate hairs. Concealed genitalia not visible in this 

 specimen. Subgenital plate nearly symmetrical, the lateral mar- 

 gins convergent, the sinistral very feebly convex, then as feebly 

 concave, the dextral as feebly concave to the style sockets, between 

 these the distal margin is roughly broadly convex, weakly oblique 

 in proximal portions, mesad truncate but when seen in caudal as- 

 pect as weakly obtuse-angulate ventrad, the angles formed all 

 rounded. Styles similar, simple, straight, cylindrical, rounded at 

 apex, each about two and one-half times as long as its width, 

 shghtly over one-quarter as long as the distance between the style 

 bases. Limbs very slightly heavier and shorter than in meliponarum. 

 Cephalic femora with ventro-cephalic margin supplied distad with 

 a very few, minute, piliform spines, which are scarcely distinguish- 

 able, terminated by a single elongate distal spine. Caudal meta- 

 tarsus equal to combined length of the succeeding tarsal joints. 



General coloration shining blackish chestnut brown, paling to 

 hazel along costal margin. Tegmina, when held against light, chest- 

 nut brown paling to hazel along costal margin. Wings transparent, 

 almost colorless, veins buffy, costal veins distad opaque, ochraceous- 

 buff. Dorsal surface of mesonotum, metanotum and abdomen 

 buffy, the latter suffused with blackish chestnut brown laterad and 

 in broad distal portion. Head shining blackish chestnut brown, ^^ 

 mouthparts and limbs mars brown, coxae and abdomen, except 

 proximo-mesad where it is slightly paler, blackish chestnut brown. 



Length of body 7.7, length of pronotum 2.2, width of pronotum 

 2.9, length of tegmen 7.1, width of tegmen 2.7, length of caudal 

 tibia 2.4 mm. 



The type is unique.

Previously known from tropical Mexico to Panama, an additional 

 female from Trinidad is before us.^^ The pronotal proportions of 

 these two specimens are identical, length 1.8, width 2.05 mm.

2* The antennae are missing. 



*" Recorded by Bruner as L. castanea Brunner (Jour. N. Y. Ent. Soc, XIV, p. 

 143, (1906).), which name is very possibly a synonym, as Brunner 's pronotal 

 measurements for the female type from Balthazar, Granada, (length 1.5, width 

 1.3 mm.), alone disagree and may easily be incorrect.
