INSECTS OF SAMOA. 



Size, small. Body elongate, lateral margins roughly parallel, covered with 

 coarse pubescence and punctures. Vertex conically produced anteriorly, 

 rounded at the apex. Three or four pairs of sensory pits along the lateral 

 submarginal areas ; the apex with long setae. Eyes much rounded laterally, 



agglomerate. Antennae slender, first 

 segment stout, slightly curved out- 

 wardly, slightly thickened at the 

 middle ; second, three-fourths the 

 length of first, thinner than the latter, 

 a little thickened towards the apex ; 

 third very slender, nearly as long as 

 first ; fourth much the longest, twice 

 as long as second, one and a half 

 times as long as first, thickened in 

 the middle. Ratio of the antennal 

 segments — 12 : 9 : 11 : 18. Rostrum 

 reaching the anterior coxae, second 

 segment (in reality this may be the 

 third) much the longest. Pronotum 

 transverse, both anterior and posterior 

 margins shallowly sinuate posteriorly, 

 lateral margins slightly rounded, con- 

 vergent anteriorly ; a more or less dis- 

 tinct submarginal depression along the 

 posterior margin ; meso- and meta- 

 notum together about half as long as 

 pronotum. Legs moderately slender, 

 covered with setose hairs, femora moderately thickened in the middle ; anterior 

 tibia about three-fourths of femur, tarsus long, a little longer than half the 

 length of tibia; intermediate femur and tibia nearly equal in length, tarsus 

 about half as long as tibia, two segments of equal length ; posterior tibia longer 

 than femur, slender, tarsus short, two segments of equal length. First four 

 dorsal abdominal segments subequal in length, fifth a little longer than fourth, 

 sixth nearly as long as fourth and fifth taken together. Connexivum obliquely 

 erect in male, turning over the dorsal surface of abdomen in female, in which the 

 dorsal surface of the last four segments is scarcely visible.
