Calvert: Odonata of the Neotropical Region. 125 



The dorsal violet spot of abdominal segment 2, which at its widest in 

 the male is more than half as wide as the segment, is here reduced to 

 a stripe never more than one-third as wide as the segment and often still 

 narrower. The dorsal surface of abdominal segment 8 is black for its 

 entire length in most of the ten specimens in which this segment is 

 present, this solid black dorsum evidently due, as some examples show, 

 to a fusion of two longitudinal stripes along the mid-dorsal line, each 

 dorsal stripe also fusing for a variable part of its length from the an- 

 terior end backward with the adjoining inferior lateral black stripe 

 present also in the male; each dorsal black stripe is occasionally 

 broken into a stripe followed by a black spot at the hind end of the 

 segment. Abdominal segment 9 has a pair of dorsal black spots or 

 short stripes extending from the anterior end to one-half or three-fifths 

 of the length of the segment, confluent with each other only at the 

 extreme base, but each one confluent to a greater extent with the ad- 

 joining inferior lateral black stripe, which latter usually, but not always, 

 reaches to the hind end of the segment; 10 pale (blue?) with no 

 black markings. In the male the inferior lateral margin of the abdom- 

 inal segments is pale yellowish or bluish, except at the hind end of each 

 segment, there being no black lines or stripes on 1-7 distinct from the 

 dorsal black ; the females agree, although the inferior lateral pale color 

 is rather wider. 



In both sexes an interrupted pale transverse occipital line may, or 

 may not, exist between the right and left postocular spots.

The variations in the form of the black humeral stripe of A. reclusa 

 resemble some of the conditions found in A. mollis. This is especially 

 true of the females, and, although four antenodal cells are more fre-
