The State of Bolivar, Venezuela, still suffers from malaria throughout 

 its extent, though the disease has decreased in certain localities where 

 virgin soil has been brought under cultivation. The town of Bolivar 

 itself is now healthy. Anopheles {Cellia) albimanus and A. (C.) 

 argyrotarsis are the Anophelines held to be responsible for transmission.

This paper is one of a series of reports on mosquitos in Germany 

 [see this Review, Ser. B, vi, p. 211] ; it deals with species found in 

 Alsace and is a preliminary study of the females intended to facilitate 

 identification by recording easily recognisable and stable characters. 

 Existing keys are unsatisfactory, as male characters have been given 

 in the case of females and vice versa, and because markings that are 

 readily liable to damage, such as those of the thorax, have been used. 

 An attempt has been made to avoid these defects in the key given 

 here to the female mosquitos found near Strasburg. In this key 

 the Aedinae are treated as a sub-family distinguished from the 

 CuLiciNAE on the form of the end of the abdomen. 



Of the species mentioned the following are briefly described : — 

 Anopheles tnaculipennis, Meig., A. bifurcatus, L., A. plumbeics, Hal. 

 (nigripes, Staeg.), Theobaldia{Culiseia) annulata, Meig., T. {C.)glaphy- 

 roptera, Schiner, Culex pipiens, L., C. hortensis. Fie. {territans, Wlk.), 

 Theobaldia {Culicella) morsitans, Theo., T.ftimipennis, Steph. {theobaldi, 

 de Meij.), Ochlerotatus {Culicada) vexans, Meig., 0. niaculatus, Meig. 

 {cantans, Meig.), 0. annulipes, Meig., 0. dorsalis, Meig., 0. ornatus,, 

 Meig., 0. geniculatus, Oliv. {lateralis, Meig.), 0. diversus, Theo., 

 0. nigrinus, sp. n., 0. nemorosus, Meig., and Aedes cinereus, Meig. 

 0. nigrinus was found in meadows in company with 0. vexans 

 and 0. dorsalis. It lay its eggs on damp ground, hibernates in the 

 egg-stage and may have several generations in a year. Besides 

 differences in the egg, larva and male genitalia the new species differs 

 externally from 0. ornatus in the absence of the gUttering femoral 

 spot, from 0. nemorosus in the presence of shining white abdominal 

 bands, and from both these species in the remarkable black ground- 

 colour of the entire body. Most of the above species are new to 

 Alsace.
