16 INSECUTOR INSCITI/E MENSTRUUS 



in referring to the fourth volume of Theobald's Monograph, I was struck 

 by the familiar appearance of the figure of the wing of Kerteszia holivi- 

 ensis (p. 1 19), an Anopheles we had not previously associated with any 

 species known to us. Reference to a proof-plate of the forthcoming Car- 

 negie monograph on mosquitoes showed that the vsang-pattem of Ano- 

 pheles boliviensis is identical with that of Theobald's Anopheles lutzii. 

 Further comparison of a specimen of A. lutzii collected by Dr. A. Lutz 

 in Sao Paulo, Brazil, the type locality, showed that the only discrepancies 

 were such as were plainly due to inaccuracies in the description. All 

 doubts as to the identity of the two forms are dispelled by a series of ten 

 Anopheles from the same general region as A. boliviensis, sent to the 

 Bureau of Entomology by Prof. C. H. T. Townsend, Entomologist for 

 the Peruvian Government. These specimens are from the forests of the 

 eastern slopes of the Peruvian Andes, the so-called Montana, and were 

 taken on the Rio Charape, September 13, 1911, and at Huascaray, 

 September 22, 1911. Comparison of these specimens with the descrip- 

 tion of A. boliviensis and with the specimen of A. lutzii hom Dr. Lutz 

 puts the synonymy beyond question. The only observable difference 

 between the Brazilian specimen and those from Peru is that on the hind 

 tarsi the black line along the dorsal surface of the first segment is some- 

 what heavier in the latter ; but there is only one Brazilian specimen for 

 comparison and the difference is not one of significance. Kerteszia boliv- 

 iensis was first described in 1 905 (Ann. Mus. Nat. Hung., vol. 3, p. 66) 

 and the specific name therefore takes precedence over A. cruzii, pro- 

 posed by Dyar and Knab in 1 908. 



Theobald's description of Kerteszia boliviensis is rather misleading. 

 He omits to mention the white rings on the palpi and one does not get 

 the impression of the preponderance of white on all the hind tarsal joints 

 which is so characteristic of the species. 1 he statement that the species 

 is a remarkably large one is surely attributable to an error, for the species 

 is of rather small stature. Furthermore, his figure of the thoracic orna- 

 mentation is inaccurate ; the two outer stripes are broader and straighter, 

 and continue to the posterior margin of the mesonotum. Nevertheless 

 this figure more nearly resembles A. lutzii than does the one originally 

 given for that species. 



The habits of A. boliviensis were first made known by Dr. A. Lutz. 

 The larvae occur exclusively in the water held by the leaves of epiphytic 

 Bromeliaciae and the insect is consequently strictly a forest species. The
