postscutellum nigrum. A P.leto segmento tertio dorsali cum 
sequentibus pilis nullis erectis vestito, segmento 7 ventrali, cum 
preecedentibus, pilis erectis tantum brevissimis vestito, facile 
distinguendus. Tegule minutissime punctate. Abdominis 
segmentum primum latissimum et cum secundo nigerrimum. 
Certainly distinct from the preceding by the differently clothed 
apical male ventral segment—a very important character. In 
both the tegule are for the most part feebly and very minutely 
punctate, the punctures feebly impressed.

26. PARALASTOR ORDINARIUS, Sp. n. 
9. Nigra, clypeo albido-flavo, macula diseali nigra; macula 
interantennalis, una utrinque postocularis, et due pronotales, 
pallide flave. Tegule nigricantes, in parte exteriore testacesx, 
postice flavo-notatee. Abdominis segmentum primum postice 
albido-flavo-fasciatum, fascia utrinque paullo dilatata ; segmenta 
sequentia simpliciter (nec late) fasciata. Tibi  tarsique 
rufescentes. Clypeus latus, brevior, apice late et levissime 
emarginatus. Frons capitis crebre punctata. Mesonotum dense, 
minus grosse punctatum, postscutello inermi. Propodei latera 
fere equaliter rotundata. Tegule ex parte magna lzevissime, 
polite, impunctate, Abdominis segmentum primum subcrebre 
punctatum, fascia pallida apicali puncta multa ferente. Ab- 
dominis segmentum secundum dorsale basim versus subfortiter 
convexum, ventrale, post suleum, fortiter elevatum, elevatione 
summa haud prominente. Ale subhyaline, parte costali magis 
infuscata, stigmate medio pallescente. Long. 85mm. 
A rather commonplace species, chiefly noticeable as having 
several pale abdominal bands.

27. PARALASTOR PUNCTULATUS Sauss. (PI. I. fig. 17.) 
(3 =P. albocinctus Sm.% 2, var. =similis Sauss. 2) 
In this species the apex of the clypeus is not always quite 
truncate, but is sometimes very faintly concave or has the margin 
a little sinuate. The basal abdominal segment is less strongly 
transverse than in many of the allied species. It is certainly 
variable both in small details of colour and structure, and I 
believe that P. albocinctus Sm. is only a male of this species, and 
similis Sauss. a slight variety. Saussure, in his first deseription 
of the latter, says that the second ventral segment of the abdomen 
is “sans tubercule,” and in his supplement he gives the presence 
or absence of a tubercle as the only distinctive character between 
the two forms. As in other species I have found that the trun- 
cation of the segment is sometimes more evidently raised or 
produced in some examples than in others, this minute distinction 
seems hardly sufficient. 
The male of punctulatus is abundantly distinct from any of
