@.. Nigra, clypei lateribus deflexis (parte apicali excepta), macula 
interantennali, duabus postocularibus, pronotalibus, mesopleura- 
libus et scutellaribus cum parte tegularum, flavescentibus, aut 
plus minus aurantiaco-flavis. Abdominis segmentum primum et 
secundum late aurantiaco-marginata, fascia secunda utrinque 
ante medium segmentum protracta, segmentis sequentibus, plus 
minusve aurantiacis.  Tibie tarsique rufescentes. Clypeus 
(lateribus deflexis exceptis) deplanatus, nitidus, fortiter in parte 
apicali punctatus, apice subfortiter emarginato et producto. 
Frons cum thorace fusco-pilosa. Mesonotum grosse punctatum, 
inter puncta minutissime punctulatum, sive quasi granulatum, 
postscutello tuberculato, tegulis densissime punctulatis, opacis. 
Ale subhyaline, parte costali infuscata. Abdominis segmentum 
primum ex majore parte subtilius nec dense punctatum, secundum 
basim versus minus fortiter convexum, tomento pernigro vestitum, 
pilis erectis parcissimis. Segmentum 2 ventrale post suleum 
suum fortissime elevatum, elevatione summa, desuper visa, sub- 
angulata. Long. cireiter 12 mm. 
This is a less robust species than the preceding, and the thorax 
is notably longer. The flat portion of the clypeus becomes very 
narrow posteriorly, being closely adapted to, and continuing the 
plane of, the interantennal plate, when viewed from the side.

63. PARALASTOR MEDIUS, Sp. n. 
2 precedenti cognatissima, clypeo breviore, hasim versus fortiter 
sed sparsim punctato, propodeo utrinque maculato, distinguenda. 
Very similar to the preceding, but the coloration is still 
yellower (less orange), the clypeus is reddish apically and the 
yellow colour of the sides extends to the apical teeth. The 
yellow pronotal markings nearly reach the tegule, instead of 
being confined to the front half; the band of the basal abdominal 
segment is different in form, being emarginate in the middle of its 
front margin, and the second is only a little widened at the sides ; 
the legs are much more pale in colour. Strueturally, the clypeus 
easily separates the two forms.
