Priophorus munditus n. sp. 



$ . Body black with the following parts white : trochanters, ring 

 on distal ends of femora, tibiae except infuscated distal ends of meta- 

 tibiae, and tarsi except metatarsi ; clypeus broadly shallowly emarginate, 

 almost truncate ; median fovea deep, broad, twice as long as wide ; 

 frontal crest hardly thickened, broadly broken, practically wanting ; 

 ocellar basin distinct, flat, impression extending ventrad from median 

 ocellus, lateral walls linear, distinguishable; antennae with third and 

 fourth segments subequal, the fourth slightly shorter; wings infuscated, 

 distal portion clearer ; veins, costa and stigma brownish, spinulae dis- 

 tinct; saw-guides retracted. Length 5 mm.

The form of the ocellar basin and median fovea will dis- 

 tinguish this species from acqnalis Nort. 



Demand the Metric System! 



EDITOR ENTOMOLOGICAL NEWS Your attention is respectfully called t 

 the importance of the world-wide movement for metric standardization 

 of weights and measures. It is an advance in which all are interested. 



More than 100,000 petitions are on file with the Department of Com- 

 merce, Washington, D. C, demanding legislation which will establish 

 the decimal metric system for general use in the United States after a 

 liberal period of transition. Many of these petitions are from organi- 

 zations having hundreds and thousands of members. 



The present session of Congress is being called upon to enact pro- 

 gressive metric laws. Will not your publication strengthen this demand 

 by strong editorial support? You can aid powerfully in establishing the 

 logical decimal system. 



"Get this good thing done in 1921." 



Sincerely yours, 



AuiiRKY DRURY, Secretary-Treasurer, World Trade Club, 



San Francisco, U. S. America.
