Tlie well devel()])ed meiitum has a similar transverse row of Infio 
setae. Tlie lobes of the glossae and ]>araglossae are rounded and ot 
approximately eijual length, forming a subeonieal extension to tho 
laluum. The stout palp is approximately equal to the greatei 
width of the laljium and is elosely eovered with spinous setae. Or 
the third segment the inner margin bears distally a small groui 
of peetinatt' bristles. The terminal segment is oval or sub- 
glolmlar in sha])e; densely elothed with short simple setae and bear- 
ing apieally a number of sensory papillae in a sub-(dreular row. 
Tiioraeie Appemlaoes.—Tho legs (fig. 4) are stoutly developed' 
and jirojeet well beyond the lateral margins of the thorax. The 
femur is slight, short, and has a group of three peetiiiate setae iin- 
mebately external to its articulation with the tiliia. The serrations^ 
are devehqied on both margins of the setae and along their entire- 
liugtli, differing, thus, from those of the head and mandible. The' 
tibia and tarsus avv moderately elongate, the latter bearing sym- 
metrical, elongate an 1 only sli-ditly curved claws (fig. 4a). A 
short median ]>ulviliiis is iirescut as a reduced, inwardly curved 
hook. 
The 'mest)sfrniite (fig. 3a) is small, obtusely pointed and set 
with two double rows of setae on each side. 
The larger melasternite (fig. 3) is rounded apieally, slightly 
emarginate, and beai's a single set of combs arranged on each side. 
The setae of both nieso- and metasternites are typically pectinate. 
A bdominal appendaefes.- — Ventral styles occur only on the eighth 
and ninth sternit(\s. Those occurring on the eightli segment are 
large and about two-thirds the length of those on the next segment. 
In the f(unale the latter pair are slightly shorter than the extended 
processes of the ninth sternite (figs, la and lb). 
The ovipositor (figs, la and 8) is elongat<' and but slightly 
sdiorter than the extended processes of the ninth sternite- Both 
dorsal and ventral rmlves carry fine bristles only. 
The penis (fig. lb) is typical, short and profusely bristled. 
Itcmarls: This species appears to have its closest affinities 
with the species A. produeta described by Escherisch (1904). Erom 
that species it may be readily distinguished by the length of the 
ninth sternite, the processes of Avhicli in A. produeta are extremely 
elongate, being shown in his illusti'ation as more than tAvice the 
length of the accom])anying styles. The tenth tergite of A. spJen- 
deus, too, is more pointed and has a different arrangement of setae. 
Aerotelsa devricsiaua has a long acute telson and apparently 
AAholly lacks the extended processes on the ninth sternite. It ex-
