his figures 10-15, he applies the same name to a ventro-lateral 
part (maxilla lamina) forming the bases of the maxilla protract- 
ors. Qbviously the same name can not be used for two 
different pn Probably the piece termed maxilla sclerite 
in Fig. 17, is homologous to the fulera of D. cingulatus. 
Genae. These sclerites beginning from below and behind 
the eyes and extending downwards to include the base of the 
antennae form the lateral walls of the head in the region of the 
epicranium. Ventrally these come in contact with the gulae. 
Maxillary Laminae (Mx. La. Fig. 4B), termed ‘ Lovae’ 
(Parsheley) ' Maxilla plates’ (Muir sae Kershaw), ‘ Maxilla scle- 
rite’ (Heymons), are two triangular plates, which begin from the 
base of the antennae and extend to the tip of the head, thus 
forming the ventro-lateral boundary of the mouth. Their dorsal 
edges come in contact with the ventral edges of the fulera, 
while ventrally they enclose the membranous base of the ros- 
trum. These sclerites, as above stated, form the base for the 
attachment of the maxillary dicen st Heymons considers 
these to be part of the embryonic maxi 
The postero-ventral portion of the had is supported by 
flat plates called gulae (Gu. Fig. 2). ‘They extend backwards 
to the occipital foramen. Antero-laterally they are continued 
with the maxillary lamina while their median region forms the

cale (Bu. Fig. 4B), described as chitinized plates on 
the ead. of Anasa irietis by Tower are merely folded portions 
of the membranous base of the rostrum, protuding between 
the latter and the maxillary laminae. 
The head possesses one pair of feelers or antennae (Ant. 
Fig. 1, 3b). They are black, 8°5 mm. long, free and capable of 
movement in all directions. They consist of 4 segments with 
an antennal tubercle at the base. Segment I is the longest 
(3 mm.) of all. Its proximal end has three stout inwardly 
pointed spines. Segments II and IL] are 2:25 mm. and | mm. 
long. The fourth is club anes 2.5 mm. Stes entirely
