 condensing them into these notes. 



It is well knowii that, so for as science has as yet been able to 

 establish, tliere are three diseases whicli are trausmitted by mosquitoes, 

 iiamely: íilariasis, malaria and yellow fe ver. But it may 

 be antieipated, as Blancliard remarks, tha the progresa of scieuee 

 pnll some day disclose that mosquitoes are the transmitters of certaiii 

 parasitical diseases the etiology of which is very obscure. From all 

 appearanees leprosy is one of these (Blanehard). 



Indieations are not wanting, which teud to show that the followiug 

 diseases are produeed by mosquitoes : Scurvy, which according to A. 

 Devé ( N o u V e 1 1 e t h e o r i e sur la n a t u r e d u s c o r b u t, 

 These; París, 1859), is ''a variety of malarial intoxication" ; Den- 

 gue, which according to II. (irabham ("Mosquitoes and Dengue," 

 Medical Eecord, 1902, V. LXI, p. 204-207) is transmitted by a 

 Culex, although he does not say by what speeies ; the Bubonic Plague, 

 according to La Bonnardiere et Xanthopnlides ("De l'existence des 

 haeilles pesterix dans le corps de un moustique de ki chambre d'uu 

 pestifere," Aúnales d'hygieno ]! ubi i que et de medicine 

 légale, 1902, V. XLVII, p. 232) ; the ulcer of tropical countries and 

 non-malarial splenomegalia, the disease known in India as Kala-azar, 

 although Blanehard says that the appearanee of the leishmanias 

 at the same time as the try paño somas seems to indicae that they 

 are transmitted by T a b a ni d a e ; the Verruca, according to W. Dub- 

 renille ("J^a Verruga du Perón et won etiologie," Journal de 

 Medicine de B<)\-deaux. ,luly 23, 1904, V. XXXIII, p. 215): 

 Carate, Pinta disease, Cancroid and Malta feveí-, due to the Micro - 

 cocus melitensis conveyed by tho Theobaldinella spathipal- 

 pis mosquito (Blanehard, Les mous tiques, p. 5-t3-48). 



We will not increase the volume o I' this work, which is intended to 

 describe merely the mosquitoes found in the Island of Cuba, with 

 a chapter dealing with organography in general, since we take it for 

 granted that those who do us the honor of readiug this have a general 

 knowledge of Entomology ; but even if this were not the case, the mi- 

 crophotographs which ilústrate the work will compénsate any deffie- 

 iences in the tiresome descriiitions. Neitliei' do we ])ropüse to deat with 

 the technique of the capture of mos<iuitoes, the mounting of them and 

 the study of the parasites in their interior, inasmuch as these topies 

 have been treated in a mastenly manner and will admirable detalls

 the idea of the author through a translation. 



Not all the Cuban species will be found photographed in this work,
