Abstract:

The eggs and 5 nymphal instars of <I>Harmostes reflexulus</I> (Say) are described and illustrated. Eggs were 1.29&#215;0.45 mm (mean values), white, elongate oval, with slight indentations on either side of median longitudinal ridge. There were 2 micropylar processes per egg. First instars were light green, the succeeding instars reddishbrown to brown. Mean length measurements of nymphs were 1.62, 2.38, 3.39, 4.33, and 6.60 mm in the 5 instars, respectively. Antennal segments 2 and 3 were noticeably flattened, but not dilated. Abdominal scent glands were well developed. Six types of setae were found on the appendages and body regions of nymphs and included numerous white, club-shaped setae. Trichobothria were constant in location, size, and number in all 5 nymphal instars and the adult. The structure of the pretarsus was also similar in nymphs and adults. Setal combs employed in grooming the labium and antennae were found in all nymphal instars and adults. The comb was located on the inner apical margin of each protibia. The number of setae making up the combs increased from 6 in the lstinstars to 22 in the adults. Combs were composed of short, stout, blunt-tipped, dark setae.
