with several structural differences. It more resembles a Cuspi- 

 cona, but the generic characters are those of Diapli\'ta. 



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 1-5 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 inward from the spiracles, forming an uninter- 

 rupted curve from the first to the third segment. The "strigose 

 vitt?e" in Myappena Dist. are certainly not homologous with the 

 stridulatory vittse in the Platycoraria. As the rostrum is de- 

 scribed as only passing the anterior cox?e Mvappena 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.

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
