 angles being prolonged as divaricate spines; 2.5 to 2.6 mm. long 



hamatus

Type. Measurements: Head 0.368 from apex of antennal tubercle to 

 cervicum x 0.30 mm. through tempora; cervicum 0.067 mm.; pronotum 0.30 

 X 0.335 mm.; elytra 0.53 x 0.60 mm.; abdomen 0.40 x 0.53 mm.; total length 

 1.7 mm.; greatest width 0.60 mm. 



Yellowish-brown; head and pronotum subgranular; elytra semishining 

 and sparsely but distinctly granulate, each granule bearing an erect seta; 

 abdomen semishining. Pubescence very sparse. 



Head pyriform; tempora long (0.13 mm.), nearly twice as long as the 

 eyes, rounded. Eyes 0.08 x 0.067 mm. from a dorsal view, composed of 20 

 coarse facets, circular from a lateral view. Head widest through tempora, nar- 

 rowing rapidly before eyes to a prominent, slightly upturned antennal tubercle; 

 vertex deeply and broadly sulcate between the eyes; two vertexal foveae 

 placed very near the posterior margin of the head, each fovea in line with 

 the first longitudinal row of ocular facets and each fovea less than the diameter 

 of an ocular facet. Cervicum finely, transversely alutaceous. Ventral surface 

 of the head tumid laterally, with a median longitudinal depression in anterior 

 half and a large, deep, circular median fossa in posterior half. Mentum minutely 

 granulate. 



Antennae eleven-segmented, contiguous on the prominent antennal 

 tubercle; segment I very long (0.70 mm.), nearly as long as rest of antennae 

 (second to eleventh segments inclusive 0.90 mm.), the antennae strongly 

 geniculate and nearly as long as body; the first segment swollen in basal 

 fourth, minutely granular, with a double row of erect setae on ventral face; 

 II elongate (0.12 mm.), slenderly obconical; III elongate-cylindrical (0.23 

 mm.), almost twice as long as second; IV, VI and VIII elongate-oval and 

 distinctly shorter than V and VII which are elongate-subcylindrical ; third 

 to eighth inclusive subequal in width ; club formed of last three segments, IX 

 regularly oval ; X trapezoidal from a dorsal view but in reality asymmetrically 

 transverse in the dorso-ventral axis, the ventral face evenly rounded and the 

 dorsal face longer than the ventral face and produced dorso-anteriorly; XI 

 slightly excentrically articulated toward the ventral face, as long as the pre-
