into “ retort-shaped organs,” and the second maxilla form a short 
under lip which is inserted on the short prothcrax. The piercing 
stylets are very long, lying in a groove of the under lip, and at 
their base forming loops which are enclosed in a dermal sac. This 
is the structure also in Coccide, as Dujardin and Mark shew 
[and is well seen in the larval seventeen-year Cicada.—G.M.]. 
The cesophagus is narrow, extending as far as the abdomen, 
where the stomach and beginning of the mid-intestine coalesce 
with the hind-intestine (Fig. 5), the two parts winding round each 
other in several turns. This coalescence is caused by the contrac- 
tion of the mid-intestine. Mark shews that in Coccide the ar- 
rangement is different, the end of the cesophagus and beginning 
of the stomach having a small winding loop which is received 
into a sac formed by the hind-intestine. This latter is also the 
way in Cicadidæ. The malpighian vessels are four, short and dis- 
tinct, their ends running into a suspensory ligament. They are 
wanting in Aphides and Chermetide.—G. Macloskie. 
Entomotocicat News.—A paper by Dr. E. Witlaczil, on the 
morphology and anatomy of the bark lice (Coccidz) appears in 
Zeitschrift tür Wissens., Zoologie, issued Dec. 31, 1885. i. 
R. von Limbeck has investigated ( Litzungsber, K. Akad. Wissen- 
schaften, Wien, 91, 1885, p. 322) the histology of the yellowish- 
brown and white muscles of insects ; the former are thoracic and 
belong to the wings, the latter are abdominal muscles, and largely 
form those moving the hind limbs. According to Science for 
Jan. 15, the city of Mexico has. for a number of months past 
been afflicted with a scourge of mosquitoes, which have abounded | 
SO as to cause sickness, and, it is said death, by their poisonous - 
bites. The grand prize in anatomy and zodlogy of the French 
Academy has been given to Dr. J. Chatin for a work, as yet un- 
published, on the tactile organs of insects and Crustacea. The 
Transactions of the Entomological Society of London, Dec. 2, 
1885, contain an interesting life-history of a trap-door spider 
(diypus piceus), by F. Enock; also an essay on the classification 
of the Australian Pyralidina, by E. Meyrick. He divides the 
group into thirteen families, and estimates the number of de- 
scribed species throughout the world at 2500. He thinks that 
the Phycidz may be regarded as a development of the Galleriadz, 
the Botydide of the Scopariade, and the Hydrocampide and 
Musotimidze of the Pyralidide. * * * The Tineodide (formed
