WASP-GENUS PARALASTOR, 591 
35, PARALASTOR ROSEOTINCTUS, sp. nD. 
@. Nigra; abdominis segmentum primum supra (se. parte 
declivi excepta) fere totum pailide aurantiacum, antice nigro- 
emarginatum ; segmentum secundum fascia lata apicali, lateraliter 
feve ad medium attingente, ornatum. Clypeus maculis duabus 
curvatis magnis lateralibus, nonnunquam ad basim una con- 
junctis, notatus; macula interantennalis magna, postorbitalis 
parva, Antennarum articulus primus antice, aut totus, aut 
basim versus, aurantiacus aut rufescens. Macule pronoti 
magne, ad medium ejus longitudinem attingentes, nonnunquanmr 
una conjuncte (sc. haud interrupte), et fasciam formantes. 
Mesopleura notata ; tegule mesonotum juxta nigricantes. Scu- 
tellum, postseutellum et propodeum aut utrinque notata, aut 
tota nigra. Ale hyaline, parte costali parum late infuscata. 
Tibie tarsique rufescentes. Color picturaticnis est insolitus, 
pallide roseo-tinctus. Clypeus subnitidus, fortiter punctatus, 
puncturatione minutissima interstitiali sat distincta, apice leviter 
emarginato. Frons capitis densissime (nec. profunde) rugose 
punctata. Anguli pronotales distincti, nee acuti. Mesonotum 
sat grosse rugoso-punctatum, tegulis in parte exteriori haud 
evidenter punctulatis, postscutello inermi. Abdominis seg- 
mentum primum haud evidenter transversim impressum, rugoso- 
punctatum ; secundum dorsale fortissime in formam conicam 
elevatum ; ventrale, post suleum suum, distincte (nec fortissime) 
supra partem suam basalem elevatum, elevatione summa late 
rotundata, haudquaquam subacute prominula. Long. 8°5 mm. 
The variation in the colour of the hind parts of the thorax is 
unusual, but I have no doubt the two examples are of the same 
species. The clothing of the thorax is not at all dense, so that 
the sculpture is very easily seen. The very strong and pointed 
elevation of the second dorsal segment of the abdomen is like that 
of P. tuberculatus Sauss. alone of all the species known to me.
