HYMENOPTERA — MASARIDES. 943 
The genus Ceramus Zatr. (Gnatho Klug) is very interesting on 
account of its upper wings not being folded longitudinally, and having 
only two submarginal cells, as in the Masarides ; the labial palpi also, 
as in those insects, are larger than the maxillary, which, according to 
Latreille and Fonscolombe, have only four joints. Klug figures them 
as 3-jointed, but I can only observe two joints in C. Lichtenstenii AZ. 
M. Fonscolombe (Ann. Soc. Ent. de France, 1835) has given a de- 
tailed description of C. Fonscolombii Zaér. (a species inhabiting the 
South of France, for which I am indebted to M. Serville), which forms 
cylindrical tubes at the entrance of its burrows (like Odyn. muraria), 
which it destroys after it has completed the construction of its nest. 
The genus comprises two European and two South-African species. 
Paragia Shh. has also only two submarginal cells; but its eyes are 
oval (not reniform), and its mandibles resemble those of the social 
species, whence Mr. Shuckard considers it is the Australian repre- 
sentative of Vespa. 
Some anomalous species of wasps, forming Latreille’s family Ma- 
SARIDES, agree with the Eumenide in having the fore wings longi- 
tudinally folded and the eyes notched, but differ in the antenne being 
inserted wide apart, and composed apparently of only eight joints 
(jig. 87. 12. ant. Czlonites apiformis ¢ ), the last being large, rounded 
at the tip, and forming a solid mass with rudimental articulations, in- 
dicating the terminal joints; the labium is terminated by two very 
long sete, which when at rest are retractile within the basal tube of 
the mentum; the upper wings have only two perfect submarginal 
cells; the clypeus is emarginate in the centre, with the labrum 
inserted into the notch; the maxillze are short and obtuse, with the 
maxillary palpi very small, consisting of two, three, or four joints. 
The insect described by Fabricius (£né. Syst. vol. ii. p- 284.) from 
the collection of Desfontaines, and figured by Coquebert (Zdlust. 
Iconogr. tab. 15. fig. 4.) under the name of Masaris vespiformis, is 
evidently a inale, from the elongated antenne and abdomen*, which is 
armed on the under side with two tubercles near the base. The 
insect figured in the great work on Egypt, which Latreille regards as 
forming a distinct subgenus, is a female. I have received it from Dr. 
* Fabricius nevertheless says, “aculeo recondito punctorio,” perhaps only from 
analogy.
