pores, 1 mesad of each outer tooth. A row of 
minute pores in the position of the submarginal 
line. Thoracic and abdominal tracheal folds, 
pores, clefts, and combs absent. Cephalic area 
posteriorly with 2 paramedian lobes mesad of 
the eye spots, each bearing 4 short spines. Pores 
and spines on thorax as in figure. Abdomen, first 
segment with paramedian processes, a pair of 
nearly contiguous pores on second segment, a 
median abdominal ridge laterad of which are 5 
pairs of short blunt spinous processes, 1 pair 
more acute laterad of orifice. Eighth abdominal 
seta bases laterad of orifice about mid-length. 
Caudal seta bases slightly closer together than 
width of orifice and in same line as submarginal 
line of pores. Vasiform orifice (Fig. Id) sub- 
circular, slightly transverse. Operculum sub- 
cordate, filling orifice. Lingula not visible. 
holotype: Pupal case on slide mount. De- 
posited in Institut Frangais d’Oceanie, Noumea, 
New Caledonia. 
PARATYPES: In author’s collection. 
TYPE LOCALITY: New Caledonia, PDothio, 
coll. F. Cohic. 
FOOD PLANT: Undetermined. 
OTHER MATERIAL: From undetermined hosts, 
Carenage 17/12/54 and Montagne des Sources 
8/4/55, coll. L.J.D., also in association with A. 
spinithorax at Dothio. 
This species shows some affinities with Aleu- 
rotrachelus because the outer boundary of the 
clear pores mesad of the marginal teeth is raised 
and simulates an inner row of teeth. In this the 
species resembles A. dissimilis Q. & B. and A. 
serratus Q. & B.

gion with 1 pair of paramedian hairlike setae 
and anterior to these 2 pairs of longer stout 
spines. Posteriorly on the thorax is 1 pair of 
short conical spines and a pair of very long
