Maclsa 1968 Journal 14 July Barrow, Alaska Counted the remaining tanglefoots and the Catch from the can traps; cleaned and regressed the boaros, then spent the rest of the afternoon making the charge and harvesting my sundry sampling Devices. In the evening went to the camp movie with Bobby and Beverly, then drove out and spent the rest of the evening at Birrich. Another day of warm, dry wind. 15 July Barrow, Alaska Calm and very warm today. Pete began the 2nd run of the traps. I drove out with him early in the morning to lines IX & X. Insects were all over the place - especially Prionocera. Went back to camp and came back with the vacuum machine. Used this to take a sample, then spent the rest of the morning hand-picking a sample of Prionocera and sweeping for other Diptera. Found a new species of Tipulidae - a bit larger than Pedicia, black with thin yellow bands on the abdomen and a conspicuous yellow spot on the prothorax, in front of the wings. I first noticed it because it was flying more adeptly than any of the other tipulids. Collected 47♂ 86♀ and 44♀♀ Prionocera - an even ratio taken by a human predator when both sexes are winged.
