Tlie fulluwiug points vvtie iiolcd in the adult larva : Aiitennye short, 



truncate, nearly straight, smooth, entirely devoid of spines. Lateral tuft 



represented by one short hair. A short lamella and several short spines 



at the apex. (Fig. 25, 6.) Labial plate columnar, lateral teeth strongly 



curved, upper nearly straight. (Fig. 25, 7.) Air tube short, a little 



longer than broad (at the base), subconical ; row of pecten of eight curved 



and spinous teeth, their serrations reduced to a row of fine elongated 

 spicules. (Fig. 25, 8, 8'.) Eight pairs of four-fid hairs are attached to 

 the central region of the tube posteriorly, forming a characteristic cluster. 

 Scales of comb 15-20, each consisting of a thin oval basal plate 

 bordered with fine radiating hairs. (Fig. 25, 10.) Terminal portion of 

 the ninth segment completely encircled by a ring of chitin. Terminal 

 tufts of hairs springing from distinct plates ; the upper tuft of only two 

 pairs of hairs, the lower of seven pairs, the latter feathered. Anal 

 papillae very long narrow cylindrical, relatively larger than those of any 

 other Jamaican Culicid ; papillae stiffened with fine spiral chitinous 

 threads. (Fig. 25, 9.) 



Pupa : siphons short, apertures bordered internally by many fine 

 branching hairs. Terminal appendages broad, segments nearly equal • 

 mid rib extending as a fine hair a short distance from the free margin. 



OcsEKVATioNS. — A fcw Hviug larvie of this species, with some of 

 C///<rjc 5^^/^/t?r, Theo., were sent in September, 1905, by Major Hassard, 

 after whom I have named the species, collected by him from a tank at 

 Newcastle. They were easily distinguished by their pale straw-coloured 

 bodies and dark heads and siphons. The singular group of hairs at the 

 back of the siphon, and the very long anal papillae at once attracted 

 attention. In January, 1906, I found some specimens in a water barrel 

 at the Government Botanic Garden at Castleton, alt. 500 feet, living har- 

 moniously with Stegomyia fasciaia^ Fab. The adult insects bred from these 

 bit vigorously. 1 have placed this species provisionally in the genus 

 Culex ; the characters of the larval siphons and antennae clearly point to 

 its being an aberrant form. 



5. Howardhia Walker i^ Theo. — This species is stated to cause much 

 annoyance during the day ; it abounds in woods, breeding in Bromelias. 

 I have already described the larva in my Monograph on the Culcidse of 

 Jamaica ; the following noteworthy points were omitted : two stout 

 branched hairs are present on the clypeus ; the rays of the hair tufts on
