Properly^ words ending in -peza are pronounced with a short e. 

 Micropsia, Plaiypesa, Tanypeza, Leptopesa. Since in EngHsh 

 pronunciation z is no longer the double consonant dz, these words 

 are commonly though improperly given as Micropeza, Platypeza, 

 Tanypeza. In the same group comes Trioza, but usage has made 

 the vowel as well as the syllable long in Chyliza, Pipiza, Myzus 

 and its series of related -myza genera, hke Agromyza, Antho- 

 myza, Helomyza, Phytomyza, and Sciomyza. 



Narnes ending in -opus give some confusion until the deriva- 

 tion is known, ops means face, but pous, with root pod, means 

 foot. CEddpa Psildpa, Systrdpus, Cixldpa, Chrysdpa, Desmome- 

 topa come from the former root, while CEdopus, P silo pus, DoU- 

 chopus, Bythoscopus, Platypus, Polycentropus and Gyropus are 

 names referring to leg structures. 



The following generic names are formed with the long Greek 

 omega in the accented syllable. Diabrotica, Diplosis, Melanotus, 

 Haplda, Prionus, Sitdnes, Cyrtopdgon. Names ending in -odes 

 have an accented penult. Aleyrddes, Eleodes, Oncodes, Or- 

 neddes, Melissddes, Phengodes. 



The short omicron occurs in the penult of : Agrotis, Chirono- 

 mus, Dendroctonus, Omophron, Pericoma, Pleocoma, Pyrochroa, 

 Stenolophus, Synchroa, Merodon, Toxotus, Neocota, Xyleborus, 

 Xylocopa. Similarly coris (bug) and toma (temno, cut) throw 

 the accent forward : Geocoris, Leptdcoris, Thyreocoris; Hylo- 

 toma, Neurotoma, Pentdtoma, Tritoma. 



The diphthong oi is not found in classic Latin although it is 

 good Greek, Hence when it is brought into Latin form in proper 

 names derived from the Greek the o and i should be separately 

 pronounced. Hence Culicoides, Sanninoidea, Blattoidea and 

 Coleopteroidea are preferable to pronouncing the oi as in coin. 



A class of genera, the pronunciation of which is disputed, in- 

 cludes those founded on personal proper names. Should the 

 pronunciation of the genus name follow Latin rules, thereby often 

 distorting the proper name so as to bear little resemblance to its 

 original form, or should the original pronunciation, even of 

 foreign names, be retained? In as much as such genera are 

 founded as a mark of honor the latter course seems preferable. 

 Some examples follow to show the difficulties experienced with
