with several structural differences. It more resembles a Cuspi- 
cona, but the generic characters are those of Diaphyta. 
Myappena capito Dist. 
Distant says that “‘this genus appertains to the group of 
genera distinguished as Platycoraria Bergr.,’ but in the de- 
scription he writes: “Abdominal segments 7-5 with a trans- 
verse Strigose vitta behind the spiracles’ (the italics are mine). 
I have not seen this insect, but it can certainly not belong to 
the Platycoraria, as in this group the strigose ventral vitta is 
situated far imward from the spiracles, forming an uninter- 
rupted curve from the first to the third segment. The “strigose 
vitte’” in Myappena Dist. are certainly not homologous with the 
stridulatory vitte in the Platycoraria. As the rostrum is de- 
scribed as only passing the anterior coxze Myappena cannot 
even belong to the Halyinae. Its position will remain enigmati- 
cal until it has been re-examined and redescribed by a hemip- 
terist having access to the type. 
New Species of Lyttidae, with notes on Described 
Species (Coleop.).

(Studies from the Laboratory of Tropical Medicine and Hygiene, 
under the direction of Creighton Wellman, Tulane University of 
Louisiana, No. 2). 
The writer has for several years been interested in the Lyt- 
tidae (Meloidae auctt.) on account of their parasitic habits and 
the bearing of the facts regarding their habits on the general 
question of parasitism, and also because of the employment by 
African and Oriental natives of substances prepared from these 
insects as medicines, aphrodisiacs, poisons for suicide and mur- 
der, etc. 
In the course of an examination of large amounts of ma- 
terial from the British, Berlin and Indian Museums, the Pusa 
collection of Bengal, several private collections and my own 
cabinet, I have accumulated a number of notes which do not
