tantum mediocriter convexum. Segmentum 2 ventrale, post- 
suleum, fortissime abrupte elevatum, elevatione summa conspicue 
prominente, sive tuberculata; segmentum ultimum Jatum, sub- 
depressum, brevissime pubescens. Alarum pars costalis usque ad

51. PARALASTOR ORIENTALIS, sp. n. (PI. I. fig. 21.) 
Niger, clypeo, macula interantennali, duabusque postocularibus, 
antennarum ¢ articulo primo antice, pronoto supra usque ad 
tegulas, scutelli et postscutelli aut fascia completa aut maculis 
duabus, propodeo utrinque, abdominis segmento primo (parte 
declivi except) fere toto, apicali fascia secundi cum sequentibus, 
tibiis tarsisque et sepe parte femorum majori, aurantiacis. 
Clypeus et macula interantennalis sape, quam macule cetere, 
flavescentiores. Ale distincte ubique infuscatee, costali parte 
saturatiore. Clypeus distincte, nec profunde emarginatus, 
fortiter, ¢ multo obscurius, punctatus, puncturatione minutissima 
densa et conspicua. Mesonotum dense rugoso-punctatum, scutello 
inermi, tegulis fortiter punctatis. Abdominis segmentum primum 
distincte punctatum, pilis erectis perparce vestitum : ; segmentum 
secundum tomento pernigrum, pilis erectis carens, fascia apical 
latera versus paullo latiove. Segmentum 2 ventr ale, post sulcum, 
fortissime elevatum, elevatione summa prominula, anterius 
producta, segmento ultimo ¢ subdepressum, pubescens, pilis 
erectis parum vestito. Long. 9-11 mm. 
The orange colour varies in depth, being redder in some and 
yellower in others. Sometimes there are two orange spots on the 
mesonotum in front. There is also variation in the amount of 
puncturation of the tegule. I have seen only six examples, and 
four of these are without special locality. 
Hab. New South Wales, 1 2 (British Museum); 1 2, Queens- 
land, Bundaberg, taken by myself: 2 ¢ 2 2, Oxford Museum, 
and 1 2, British Museum, without special locality. 
52. PARALASTOR LACHESIS Sauss. 
This species has the same coloration as P. orientalis, and may be 
identical with it. Owing to the fact that the sculpture of the 
tegulz is not referred to in Saussure’s description, I cannot place 
it in my tables. The clypeus is said to be “ strongly emarginate,” 
whereas the term is not as a rule used by Saussure for species 
which have the clypeus no more strongly emarginate than 
P. orientalis. 
Hab. Yasmania, according to Saussure, but I have seen no 
Tasmanian species with this style of ccloration, which is so
