Rio San Miguel, 13°25'N, Dept, San Miguel Feb, 2, 1924 - Feb, 21, 1926 Least Bat- Our camp was in a newly constructed wood hut which was arranged along with a series of others. The house or hut had [three] windows and one door, and the door was screened. The mosquitos commenced to come in through the open windows just as the sun sank behind the jungle and came in increasing numbers until dark when it seemed as though no more could get in. During the evening of February 14, we were taking our supper by lamp light, feeding ourselves with one hand and fighting mosquitos with the other. When I noticed a Least Bat wheeling about the room over our heads, I jumped up [and] grabbed a butterfly net and after at least a dozen unsuccessful attempts I bagged No. 11123 a female. But this was not all another was spinning about the room and it finally came to rest on one of the pole reflectors where it was shot with a shot pistol. It being No. 11122 F. Both stomachs were full of insects finely ground.
