THYSANOPTERA. — THRIPIDE. 5 
dannoso agli Olivi,” &c. in Atti dell’ Accad. de Georgofili, t. xii. and 
Guérin, Bullet. Zool. p. 12.) 
In Hill’s Decade of Curious Insects, 1773, an insect is described 
under the name of Alucita pallida (the straw-coloured Chinch), which 
is evidently a species of Thrips, of which great numbers are asserted 
to have been discharged by “a studious gentleman, very subject to 
the headach,” whilst sneezing. 
The relations of this order are very difficult: the nature of the 
metamorphoses would unite it with the Orthoptera or Hemiptera, 
whilst the structure of the wings and mouth remove it from both 
those orders ; the mouth, indeed, seems to be of a character almost 
intermediate between the Mandibulata ‘and the Haustellata; the 
setiform mandibles are very like those of the Hemiptera, whilst the 
general disposition of the other parts of the mouth are more like 
those of a real mandibulated insect. It appears doubtful to me, how- 
ever, whether the action, even of the maxilla, can be transverse, or 
whether the insect can be said to bite its food. 
The order comprises but a single family, Turipipm Leach, the 
species of which are far more numerous than has been generally sup- 
posed, as may be learned from Mr. Haliday’s valuable memoir, pub- 
lished in the Entomological Magazine, No.15. Ihave also seen some 
plates containing magnified figures of various species of the family by 
M. Heeger ; but I am not aware whether they are yet published. 


OrvER NEUROPTERA JZinneus. 
Cuar. Wings four, generally large, equal sized, membranaceous, 
with numerous areolets, posterior pair ordinarily not folded. 
Mouth with transversely moveable jaws. 
Abdomen of the females unarmed with a pungent multivalve ovi- 
positor. 
“ Scapulee and parapleure parallel and oblique.” Kirby. 
Pupa various, in some quiescent, with the limbs folded over the 
breast ; in others active,and more or less resembling the perfect 
insect ; larva with six articulated legs. 
The insects of this order, established by Linneeus, differ from those 
of the preceding orders in the membranaceous structure of their four 
naked wings, which, together with the masticatory trophi, will suffi- 
ciently separate them from the whole of the haustellated division.
