shown that his strictures were based upon misapprehension 

 and want of information (^^). 



The complete metamorphoses are known in very few species. 

 Of the following, however, conjsiderable information is 

 recorded, viz., Murgantm liistrionica (^^), Bathycoelia 

 thalassina (^^), and Tectocoris lineola (^'*). 



In Mexico, Eiischistus spurculus is made into a kind of 

 flour (^^) and eaten, while in India, Erthesina fullo (^^) and 

 Aspongopus iiepalcnds (^'^) form a part of the diet of certain 

 natives, the last named species being mixed with rice. 



The Cimicidae are probably extensively parasitized. Phasia 

 sp. and Ocyptera hicolor, among the Diptera, have been noted ; 

 Eucorysses grandis has been recorded as the host of a stylopid, 

 while a Telenomus destroys the eggs of Eurygaster and an 

 Encyrtus those of Murgantia. 



Oechalia. 



Of this genus, grisea was described by Burmeister, pacifica 

 and patrueiis by Stal. Unable to find differential characters in 

 the adults, I followed Blackburn in recognizing only one 

 species. Lately however my doubts have been revived and in- 

 creased by the discovery of two types of ova. 



Both are pale bronzy green. In the first, the upper rim of 

 the egg is furnished with from 9 to 11 whitish, black-tipped 

 capitate processes and there is no ornamentation on the opercu- 

 lum or egg-shell. These ova were found deposited on a fern 

 leaf. In the second, the number of processes was greater, 

 ranging from 14 to 16, and beside a circular row of about l-i 

 short black teeth on the operculum, the sides were reticulated
