some carpenter bees from India had in the basal abdominal seg- 

 ment a chamber, which was always full of Acari ; the females 

 alone possess this acarid cavity. The relation of these acarids to 

 their hosts is uncertain, Mr. Perkins believing that they are inju- 

 rious. A Mexican wasp {Odyncnis), which he had also exam- 

 ined, had a special Acarid chamber formed by a modification of 

 the second abdominal segment, where it is overlapped by the first ; 

 he exhibited also an Australian wasp in which this cavity was 

 located in the posterior face of the propodeum.

Exhibitions and Notes. 



Mr. Kotinsky remarked that the work of compilers of lists, etc., 

 of groups of insects is undoubtedly commendable, and to the 

 workers in those groups very useful, but like everyone else they 

 are likely to commit errors. Among the most regrettable of 

 these is the tendency to alter names without apparently satisfac- 

 tory reason or authority. To illustrate, he cited the following 

 instance : In the Transactions of the New Zealand Institute 

 Vol. XXVII p. 46, Maskell reports Mytilaspis pallida var. ( ?) 

 "on Podocarpus, Hawaiian Islands from Japan." In the Ameri- 

 can Naturalist Vol. XXXI p. 704 (1897), Cockerell, referring 

 to this variety, names it niaskelli. In compiling his list of Coccidae 

 for the Fauna Hawaiiensis in 1902, Kirkaldy disregards Mas- 

 kell's ""variety (?)", apparently overlooks Cockerell's note upon 

 this variety, and reports "Lcpidosaphes pallida on Podocarpus, 

 Hawaiian Islands from Japan." As a result, Mrs. Fernald in her 

 "Catalogue of the Coccidae" credits "Podocarpus, Hawaiian Isl- 

 ands from Japan" with both L. pallida and its variety mmkclli. 

 the one on the authority of Kirkaldy, the other of Maskell. While 

 L. pallida probably exists upon these islands, Kirkaldy apparently 

 had no authority for his record. 



Mr. Kotinsky also stated that through the courtesy of Dr. Rus- 

 sel, who is now in Japan, a colony of Chilocorus similis Rossi 

 was received from that country, three adults and five pupae arriv- 

 ing in good condition. The imagines issued from these pupae 

 shortlv after arrival and subsequently the colony was reduced to
