The present paper is based on the collection of Hispinse and 

 Cassidina; contained in the Museum of Cambridge University. 

 The collection is a representative one, in tliat it is composed of 

 species from all parts of the world. There are 271 specimens 

 representing 14 genera and about 40 species of Hispinfe and 

 34 genera and about 68 species of Cassidinfe. Owing either to 

 the imperfect condition of the specimens or to insufficiency of 

 material, I have been able to deal with only 47 genera ajd 

 80 species of both groups in this paper. 



I have studied this collection in conjunction with similar 

 material in the British Museum (ISTat. Hist.). This method 

 has aftbrded me the opportunit}^ of examining a large number 

 of examples, with the result that I have been able to study 

 critically some of Bobeman's genera and to propose some 

 alterations. I have also been able to supply information on 

 certain points which are left as doubtful in Spaeth's recent 

 ' Catalogue of Cassidinje.' In a few cases the priority of the 

 names of certain genera has been discussed. Thiee new genera., 

 one new subgenus, and two new species are now proposed here. 

 In the following list of determinations wherever the range of a 

 species is not indicated it has been reported only from the locality 

 which is mentioned in this paper. 



I wish to express my indebtedness to Dr. C. J. Gahan, who 

 has always kindly given me the benefit of his opinion on many 

 points. My thanks are also due to Mr. Scott, of the Cambridge 

 Museum, whose assistance at the initial stage of the study I wish 

 to acknowledge. This piece of work was done while I was a 

 student of the Imperial College of Science. I take this oppor- 

 tunity of expressing my thanks to Profs. MacBride and Lefroy, 

 of the zoological department of the College.
