48 INSECUTOR INSCITI^ MENSTRUUS 



absent from the fourth abdominal segment, though the side 

 patches are present. The banding is not as marked as in 

 C. territans. 



The statement on page 317 of the Carnegie Monograph, vol. 

 Ill, part i, that "the larvae are translucent," should be cor- 

 rected, as this description applies to tarsalis, not to erythro- 

 thorax. 



Culex territans Walker. 



The larvae occurred abundantly in some pools in the San 

 Diego River valley. The pools had been washed out by the 

 flood, but were regaining normal conditions. There was a 

 slight current of water through the pools and many small 

 slender reeds. The form of territans occurring here is very 

 small, the larvae strongly banded, due to the absence of pig- 

 ment in the fourth abdominal segment. There is no general 

 pigment in these larvae, but the lateral patches are present, 

 except in the fourth segment. Only very few tarsalis were 

 present in these pools. Territans occurred also in the large 

 pool described under C. erythrothorax. These larvae were 

 darker, having deep body pigment besides the lateral spots, 

 but the fourth segment was colorless. The banding was, 

 therefore, even more prominent. 



Culex species. 



A single female, bred from a pupa taken in the large pond 

 mentioned under C. erythrothorax, comes very close to deri- 

 vator Dyar and Knab (a Mexican species), and from the one 

 specimen I do not venture to separate it. It is smaller and 

 probably distinct, as Mr. Knab suggests to me, but a good 

 series will be necessary to differentiate it properly. 



Culex anips, new species. 



Male. — Proboscis long, moderately slender, scarcely at all 

 swollen apically, smoothly black-scaled, the labellae paler and 

 brownish, smooth, without setae. Palpi long, slender, smooth, 

 far exceeding proboscis, the first joint reaching nearly to end 

 of palpi, with a few stif? black setao at its tip; second and
