Psychoda aterrima n. sp. 



Deep black throughout, with black hair, but that on thorax mostly 

 brown, and some on costa of wing beyond middle, and also near tip 

 are brown; at extreme tip are a few snow-white hairs, hardly dis- 

 cernible. Wings narrow, and acute at tips, the hairs at base and on 

 basal part of costa are very long, many fully one-half as long as the 

 width of the wing, the fringe on posterior margin also very long, 

 longer than one-half width of wing; the forks of the two forked 

 veins are equally long, and both begin before the middle of the wing; 

 the wing is perhaps less hairy across the middle than elsewhere. 



Expanse : 4.8 mm.

Technical Assistant in Malaria Investigations (Male). 



The United States Civil Service Commission announces an open com- 

 petitive examination for technical assistant in malaria investigations, 

 for men only. The duties of this position will be to conduct labora- 

 tory studies of malaria, to make surveys of malarial regions, and to 

 advise in respect to the prevention of the disease. Competitors will 

 not be assembled for examination, but will be rated upon the follow- 

 ing subjects, which will have the relative weights indicated: i. Gen- 

 eral education and medical training 30, 2. Experience in laboratory 

 studies of malaria 30, 3. Experience in making field surveys 20, 4. Pub- 

 lications or thesis 20; Total 100. Under the third subject credit will 

 be given for experience in identifying different species of mosquitoes 

 and their larvae, or conducting surveys of mosquito-breeding places, 

 or applying practical measures for the prevention of malaria in a com- 

 munity. If a thesis is submitted under subject 4 it must present the re- 

 sults of original research work in some phase of malaria or other pub- 

 lic health subject. Graduation from a medical school or college of 

 recognized standing, and experience in laboratory technique connected 

 with malaria studies, are prerequisites for consideration for this posi- 

 tion. 



No application will be accepted unless properly executed, excluding 

 the medical certificate, and filed with the Commission at Washing-
