no. 3632 CARTWRIGHTIA — CARTWRIGHT 3 



elytron with sutural, four discal, and marginal costa separated by 

 wide shiny intervals; costae, without argillaceous coating in holotype, 

 high, carinif orm, about half as wide as discal intervals, which have lateral 

 rows of punctures except over apical declivity, where they disappear. 

 First discal costa widened apically into large argillaceous bulbous 

 end as wide as first two intervals and first two discal costae combined; 

 large bulbous end narrowly separated from sutural costa and from 

 second and third discal costae with slightly enlarged argillaceous 

 ends. Sutural costae not appreciably widened at apex. 



Prosternum with large, wide, triangular posterior intercoxal process. 

 Mesosternum flattened, slightly concave, sides flaring and partly 

 covering anterior three-fifths of middle coxae; meso-metasternal 

 suture as wide as length of middle trochanter. Metasternum with 

 long, deeply incised midline in slightly concave discal area, minutely 

 alutaceous, finely punctate, a slightly roughened triangular depression 

 in front of hind coxa, otherwise very finely alutaceous outward to 

 sides. 



Five visible abdominal segments, narrower at middle than at sides, 

 terminal segment about three times as long as penultimate, all except 

 terminal narrowly edged posteriorly with argillaceous coating, ante- 

 riorly indistinctly crenate, surface otherwise finely alutaceous and 

 with scattered very fine punctures, terminal with fine shallow punc- 

 tures generally separated by one diameter or less. Pygidium with 

 scabrous-argillaceous coating and low median, longitudinal carina. 



Anterior femora with perimarginal groove, six or seven long setae 

 along outer margin and row of shorter setae along posterior margin, 

 surface finely alutaceous with evenly distributed, shallow, moderate, 

 setigerous punctures separated by two or three diameters, setae 

 short, semi-appressed about as long as diameter of punctures; tibia 

 with three teeth, two terminal one on inside, one outside, and one 

 lateral at apical fourth; apical spur slender, acuminate, slightly 

 hooked. Middle and posterior femora slender, shining, setigerously 

 punctate as forefemora, complete posterior marginal line; tibia 

 slender, parallel sided, tarsi longer than tibia, long spur half as long 

 as first tarsal segment, latter subequal in length to remaining four 

 segments combined; claws very fine. 



Allotype female.— Length 4 mm, width 1.6 mm. Head outlined 

 with fine cream-colored argillaceous line close to finely reflexed an- 

 terior margin of clypeus, curving up around eyes and across base; 

 large similarly colored comma-shaped argillaceous area curving down 

 around each side of median convexity, small median frontal spot 

 behind elevated posterior margin of clypeus. Elytral costae with very 

 fine line of argillaceous coating on each side of sharp shining top.
