stout seta at pointed apex. Mandibles simple, stout at base, nar- 
rowed in apical two-fifths, arcuate externally, pointed at apex. 
Maxillary palpus three-segmented; first segment somewhat longer 
than wide, narrowed to apex; second segment a little narrower than 
apex of first, almost twice as long as wide, nearly parallel sided; 
third segment narrower at base than apex of second, almost four 
times as long as wide, gently arcuate, gradually pointed to apex. 
Labial palpus two-segmented; first segment about as long as wide; 
second segment narrower than first, a little more than twice as long 
as wide, slightly arcuate, gradually narrowed and pointed to apex. 
Pronotum wider than head, narrowed in front, wider than long, 
with >a row of four setae along front margin, a pair of setae on disc, 
four setae along lateral margin, two setae in sub-lateral series and 
six setae along posterior margin. Mesonotum about as long and a 
little wider than pronotum, with no setae at anterior margin, six 
transversely arranged on disc, two in the lateral series and six in 
the basal series. Metanotum about the same size and shape as meso- 
notum with chaetotaxy the same. Abdomen. First abdominal seg- 
ment about as wide as metanotum and half as long as metanotum; 
without setae at anterior margin; with two transverse rows of discal 
setae, the first of two setae land the second of ten setae, with ten 
setae along the posterior margin and three or four irregularly placed 
setae at each side. Second abdominal segment about as wide as first 
and almost as long as metanotum; with setae arranged almost as on 
first segment except the setae are moved forward so that there are 
two discal series of eight setae each and none along the posterior 
margin. Third through seventh segments very similar in all respects 
to second except the seventh is narrower than the sixth and the two 
'anterior setae are lacking on all but the first two segments. Eighth 
segment narrower than seventh but about as long; with two dark 
conjointly oval opercula in the middle near the posterior margin, 
divided longitudinally so that the anterior operculum is the largest; 
with chaetotaxy as on seventh segment. Ninth segment narrower 
than eighth, about as long ias wide; with two discal setae and about 
eight or ten setae along the posterior margin ; the outer apical angle 
produced on each side in a pointed fleshy urogomphus which ap- 
parently has no basal articulation and is unsegmented. Pseudopod 
produced between and beyond urogompi. Spiracles present at the 
outer margins of the mesothorax and the first seven abdominal seg- 
ments with much the appearance of empty hair follicles. 
Three specimens, Carlsbad, San Diego County, California, 17 
September 1970, on avocado leaves, Horace G. Johnson collector.
