AEDEOMYIA 893 



Dr. Grabham found the larvae in a hollow tree. 



Jamaica. 



Waverley Estate, September 1, 1906 (M. Grabham). 



The drawing of larval details has been made from alcoholic larvae sent by Dr. 

 Grabham; they are in immature condition, the abdominal plates not having 

 fully developed. It is probable that in fully mature larvae they are the same as 

 in the larva of Orfhopodomyia signifer, to which this species is very closely allied.

 Generic Diagnosis op Adtilt: 



Head short, closely applied to the thorax. Proboscis rather short and stout. 

 Palpi short in both sexes. Antenna in the female with the joints although sub- 

 cylindrical, short and stout, with basal whorls of few rather coarse hairs, the 

 dilation coarse and abundant; in the male plumose, the joints short and stout 

 towards the base, progressively more elongate and slender towards the apex, the 

 last two joints much thickened and not markedly longer than the preceding ones, 

 all but the last two somewhat thickened at insertions of hair-whorls, the hairs long 

 and abundant. Prothoracic lobes remote dorsally. Mesothorax rather short. Scu- 

 tellum not trilobate. Postnotum nude. Abdomen subcylindrlcal, truncate at the 

 tip in the female, slightly expanded at the apex in the male. Wings broad, the veins 

 on anterior half of wing well separated; second marginal cell very long, about one 

 third the length of wing; base of second posterior cell nearer base of wing than 

 second marginal cell; cross-veins well separated. Legs moderate, the femora and 

 tibiae rather short, the claws simple in the female. 



Genebic Diagnosis of Labva: 



Head large, transverse, bulging at the eyes; antennse large, curved, greatly dilated, 

 with ample tuft near middle and long terminal setae; mouth-brushes ample, normal. 

 Air-tube rather small, without pecten, with a single pair of hair-tufts near middle; 

 a pair of stout spines and small tufts apically. Anal segment elongate, ringed by 

 the plate. Ventral brush a series of long, unbranched feathered hairs, confined to 

 barred area. 



Tropical regions of both hemispheres. 



Three species besides the present one have been referred to this genus, but of 

 one, Aedeomyia americana Neveu-Lemaire, we are sure that it does not belong 

 here, being probably a Culex, while the other, Aedes venustipes Skuse, was re- 

 ferred here by Theobald doubtfully, without having seen a specimen. The 

 third species, A. catasticta Knab, is correctly referred to the genus. 



Larval history and habits. The larvae of two species are known in this genus, 

 those of Aedeomyia squamipennis and A. catasticta, the former from the 

 American tropics, the latter from the tropics of the Old World. The two larvae
