There also may be a rather distinct sexual dimorphism. Judging from the 

 form of the mandibles (Text-fig. 42) and some other features I cannot exclude the 

 possibility that L. manaica is the female of L. bulbiventris Cresson, known from one 

 male from Mexico, but more material and information is needed to be sure. 



In view of all these difficulties I give here a redescription of L. manaica. 



§. 8-7— 10 -5 mm. Black with faint to conspicuous metallic tint, mainly green to violaceous; 

 yellow are: scapus beneath, narrow bands anteriorly and posteriorly on pronotum (sometimes 

 also laterally), mesoscutum posteriorly between parapsidal vestiges, fore femur dorso-apically, 

 fore tibia at least internally, mid and hind coxa dorsally, small spot on hind coxa ventro-apically, 

 mid knee, separated streaks on hind femur along dorsal edge and another ventrally between 

 base and large tooth, hind tibia dorsally except at base. Antennal nagellum basally (at least 

 beneath) and apically red, also tegulae (sometimes sides of thorax) and tarsi reddish. Wings 

 moderately infumate, fore wing more intensively so along anterior margin. 



Head slightly broader than pronotum posteriorly, dorsally 2 •05-2- 10 times as broad as 

 long; occipital carina very low sublaterally, conspicuous on temples above, high behind ocelli; 

 temples narrow. POL about i-6 times OOL; ocellar triangle about 2-5 : 1, usually with 

 slight ridge between median and lateral ocellus and a depression at occipital carina; vertex 

 very densely deeply punctured-reticulate except laterad of each ocellus (more at median); 

 frontal protuberances moderate, scrobal carina above them strong, usually angulate in front 

 of median ocellus. Head in facial view about 1-22 (1-17-1 -27) times as broad as high, face 

 dull, densely rugulose-punctured, pubescence extremely short, whitish. Interantennal area 

 with distinct keel. Relative measurements: height of head 67, width of frontovertex 45, 

 face below antennae 45, breadth of scrobes 28, height of lower face 30-5, eye 48 : 32, inner 

 orbit conspicuously emarginate; malar space 10, mouth 35. Clypeus nearly 1*4 times as 

 broad as high, lower margin medially shallowly emarginate and depressed, without median 

 tooth, margin of rounded lateral lobes carinately raised. Mandibles with notch separating 

 lower tooth relatively large. Scapus about 2-5 times as long as broad. Flagellum plus pedi- 

 cellus 1 -23-1 -35 times as long as breadth of head, slightly clavate, apically nearly i-8 times 

 as broad as pedicellus; first flagellar segment usually i-6, second 1-5, fifth 1-2, eighth 0-95, 

 clava 1 -7-1 -8 times, as long as broad. 



Pronotum without premarginal carina (this slightly indicated in holotype) but hind margin 

 slightly carinate; surface convex, often very densely punctured (less densely so in holotype), 

 transverse thin separations of punctures higher than longitudinal ones, in places suggesting 

 fine cross-carinae ; hind margin of pronotum broadly emarginate, sides slightly to distinctly 

 converging forwards, straight ; lateral panel broadly concave, lower corner obtusely subangulate. 

 Mesoscutum not depressed, deeply and very densely punctured, hairs very short and thin; 

 parapsidal vestiges slightly longer than their distance from outer margin. Scutellum 1-1-1-3 

 times as broad as long, moderately convex, along hind margin barely depressed and with a 

 row of deeper punctures. Dorsellum about 3 times as broad as long, hmulate, hind margin 

 regularly arched and distinctly carinate ; dorsally bare, apart from admarginal crenulate groove 

 with shallow sculpture. Propodeum medially about as long as dorsellum, moderately dense 

 longish hairs (worn off in holotype) directed forwards on median area; median carina distinct, 

 plicae anteriorly obliterated. Mesopleural depression fairly deep, mainly smooth on bottom; 

 upper mesepisternum very densely irregularly punctured, upper mesepimerum with interspaces 

 faintly subhorizontally strigose and on disc sometimes as wide as punctures; interspaces on 

 metapleurum smooth. Upper edge of fore femur and tibia carinate but externo-ventral edge 

 of tibia blunt. Hind coxa moderately densely punctured and hairy, hairs in depression short, 

 directed downwards; upper edge blunt anteriorly, sharp and thin posteriorly where forming a 

 low translucent lobe; meso-ventral edge of coxa slightly curved. Hind femur (Text-figs 69, 

 71) excluding the outstanding basal tooth usually 2-10-2-18 times (in holotype 1-88 times) 

 as long as broad (small 10-13 teeth included), basal tooth in about two-fifths of length; outer 

 surface usually fairly densely and not coarsely punctured. Apex of hind tibia produced into
