black, in the other they are yellow from the clypeus to the middle 
of the ocular sinus; in Saunders’s example they nearly connect 
with the postocular orbital stripes. 
89. PARALASTOR MESOCHLORUS, sp. 0. 
@ precedenti cognatissima, sed pronoti maculis haud ad 
angulos humerales extensis, segmento 2 abdominalis ad basim 
nigro, aut tantum maculis rufescentibus ornato, colore primi 
leete aut pallide flavescente, distinguenda. Long. circiter 9 mm. 
This species is again variable, and there are evidently two dis- 
tinct forms of it, but the material is far too poor for a proper 
understanding either of its definite specific characters or of its 
variation. Of the typical form there are 2 males and | female. 
In the female the clypeus is almost truncate, red at the apex 
and along the sides, the antenne are red beneath, infuscate above, 
the scape and following joint less so than the others. There is a 
yellowish interantennal spot and a small orange one behind the 
eyes. The pronotum is red-marked in front medially and this 
colour extends back to the tegule very narrowly as a sutural line. 
The scutellum, postscutellum, and propodeum have large red 
markings, the tegule are reddish brown. Basal abdominal seg- 
ment above bright (slightly orange) yellow. Second with a dull 
orange band not occupying one-fourth of the segment, the 
following ones also with apical b bands. Hind tibie dark at the 
apex, at least inwardly. Mesopleura with a red spot. 
Clypeus of the male lightly emarginate, yellow, becoming red- 
dish basally at least in the middle, otherwise the head coloured 
much like that of the female. Pronotum with red markings, 
produced to the humeral angles and along the suture to the 
tegule. The other thoracic markings are like those of the female, 
iba bright yellow, a little orange- tinted, nearly concolorous with 
the basal abdominal segment; second segment either all black 
or coloured much as in the female, the basal spots reddish or 
brownish, if present. 
PARALASTOR MESOCHLORUS MESOCHLOROIDES, st. n. 
Female clypeus as in the preceding, but the coloured parts are 
yellow or partly yellow. Inner orbits with a yellow line from 
the clypeus extending into the sinus. Pronotum only with two 
obscure spots or faintly reddish on the suture medially. Thoracic 
markings bright lemon-yellow, the black median part of the pro- 
podeum less wide than in the male of the preceding, which these 
females resemble in appearance. Basal abdominal segment nearly 
concolorous with the thoracic markings. Second all black, the 
apical margin at most obscurely alee Tegule bright yellow 
inwardly, bad at the point of their deflexion less coarsely and 
deeply punctured than in the ples cans form. Male not known.
