2211 Chapin: Elacatidse g5 



finely but not as densely punctured as thorax, pale brown with 

 piceous markings. These markings consist of a round spot 

 in the scutellar angle, a larger round spot slightly postmedian 

 on the suture, common to both, a broken fascia at apical fifth, 

 and the lateral margins narrowly. Underparts almost black, 

 finely punctured, legs dark, tibise and tarsi lighter. Length, 

 3.7 millimeters. 



Type.— A specimen, apparently a female, from Penang, 

 (C. F. Baker); United States National Museum, No. 25054. 

 Elacatis undulata sp. nov. 



Head distinctly evenly and moderately coarsely punctured, the 

 punctures near the labrum finer than those on frons, fovea 

 on mentum large, almost contiguous, surface above with bright 

 brassy luster. Antennae reaching about the middle of thorax, 

 basal segments pale. Thorax with median smooth line, other- 

 wise rather finely and densely punctured. Lateral margin with 

 four obtuse denticles, luster brassy. Elytra rather long and 

 narrow, finely and evenly punctured, ornamental with a very 

 intricate dark and light pattern (Plate 1, fig. 11). Underparts 

 of thorax nearly black, the abdomen chestnut brown, finely 

 and evenly punctured. Legs chestnut brown, indistinctly 

 ringed with piceous. 



This species appears to be separable into two subspecies. 

 Typical form: Punctures of thorax coarser, dark markings of 

 elytra well developed, pygidium rather densely covered with 

 long pale hairs. Length, 4 millimeters. 



Type. — A male from Mount Limay, Bataan Province, Luzon, 

 P. I. (Baker) ; paratypes, three specimens from the same place; 

 United States National Museum, No. 25056. 

 Elacatis undulata subsp. bornensis subsp. nov. 



Thoracic punctures not at all confused, dark markings of 

 elytra reduced in extent, pygidium with few short hairs. 

 Length, 4.5 millimeters. 



Type. — A specimen, apparently a male, from Sandakan, Bor- 

 neo (Baker) ; United States National Museum, No. 25058. 



In this species the foveae of the mentum in the males do not 

 have the tufts of hairs sometimes found in the genus. 

 Elacatis delusa Pascoe.
