New Chalcidoid Genera and Species from Paraguay. 167 
Agrees with the original description of paraguayensis but the 
general body color is deep metallic prussian blue, verging to 
purple, greenish at the vertex and over most of the head, sides 
and undersides of the thorax and abdomen and the legs. The 
ocelli are closer together, the distance between them less than 
the distance between the margins of the eye and each lateral 
ocellus. The caudal half of the abdomen is pubescent with greyish 
hairs (dorsal aspect). Scutellum with a small bidentate plate.

Male: — Unknown. 
From a single female specimen on a minutien pin, labelled 
„Paraguay (San Bernardino), K. Fiebrig. S. V. 4193.” 
Habitat: Paraguay — San Bernardino. 
Type: Katalogue No. 31946, Zool. Museum, Berlin, 12 
minutien mounted plus female antenna on a slide in xylol-balsam. 
Although so differently colored, I am dubious concerning 
the validity of this species, since it clearly agrees with para- 
guayensis in structure, with the possible exception of the relative 
position of the ocelli. I have very little faith in the specific value 
of metallie coloration, especially in this case, since the same 
portions of the body are colored. Were the color pattern different, 
it would be another question. 
2. Perilampus minutus n. Sp. 
Female:— Length, 1.30 to 2.15 mm.; small for the genus. 
Black, opaque, the venation and antennal flagellum (ex- 
eluding pedicel), including the ring-joint, pale brown; knees, tips 
of tibiae and the tarsi straw yellow; wings hyaline. A little metallic 
blue on legs and under sides of body. Whole of the mesothorax 
densely punctate, the punctures moderate in coarseness, the 
abdomen smooth and shining (excluding pubescence), the vertex 
with very fine pin-point punctures, the punctures very much 
smaller and finer than those of the mesonotum and changing to 
fine transverse striation in the occiput; ocelli in a triangle, the 
cephalic ocellus in the cephalic aspect. within the apex of the 
scrobicular impression; the lateral ocelli separated more from 
each other than each is from the respective eye margin; mesial 
margin of each parapside, bordering the parapsidal furrow, very 
finely polygonally sculptured. Lateral threefourths of the axillae 
depressed, shining, very finely, longitudinally striate, bordered 
laterad by a distinct longitudinal suleus (dorsal aspect); the mesal 
fourth of the axilla punctured like the rest ‘of the thoracie notum. 
Scutellum terminating in a bilobed rimmed margin. Very close, fine 
greyish yellow pubescence on thorax and vertex, more scattered 
along the caudal half or more of the abdomen and denser on the 
flagellum and ventral portions of the face, but never dense and 
conspicuous through a hand-lens. Metanotum on each of side of 
meson nearly smooth, finely reticulated, a distinet median carina
