The 3rd to the .5th abdominal segments transversely impressed at 

 the base. There appear to be no secondary sexual characters. 



Hab. Biikit Timah and Mandai, in debris ; I believe 

 associated with Ants. 



Lampromalota, n. gen. 



Mandibles short and robust, the right with a small tooth. Maxil- 

 lary palpi 4-jointed, the 1st joint short, the 2nd elongate, lightly 

 curved and thickened towards the apex, the 3rd a little longer than 

 the 2nd, the 4th subulate, nearly half as long as the preceding. The 

 temples bordered below. Prosternal process obtuse. Mesosternal 

 process obtuse, rounded at the apex. Metasternal process broadly 

 rounded, not nearly meeting the preceding. Coxae narrowly separ- 

 ated. Tarsal formula 4, 4, 5. The anterior with the first three 

 joints short and subequal, the 4th nearly as long as the first three 

 together; the middle with the first three joints short and subequal, 

 the 4th as long as the three preceding together ; the posterior with 

 the first four joints short and subequal, the 5th as long as the three 

 preceding together. The tibiae without setae. 



This genus has the build of Homalota, from which it is 

 distinguished by the shining, obsoletely punctured- head and 

 thorax, and the absence of setae on the middle and posterior 

 tibiae. The specimen being unique I am unable to give 

 further details of the structure of the mouth-parts. 



101. Lampromalota brunneicollis, n. sp. 



Sub-parallel, depressed, shining. Head black; thorax pitchj''- 

 brown ; elytra and abdomen and first three joints of the antennae 

 fusco-testaceous ; legs testaceous. Length 1-8 mm. 



Head large, black, shining, transversely suborbicular, the front 

 truncate, eyes rather large, templft rounded and converging, sUghtly 

 constricted behind ; puncturation exceedingly fine and sparing and 

 without visible ground-sculpture. Antennae with the first three 

 joints fusco-testaceous, the others black ; the 2nd joint shorter than 

 the 1st, the 3rd shorter than the 2nd, the 4th as broad as long, the 

 5th to the 10th transverse, gradually increasing in breadth, the 

 penultimate fully twice as broad as long, the 11th oval. Thorax 

 transverse, a little broader than the head, widest just behind the 

 anterior angles; the sides narrowed and rounded anteriorly, more 

 strongly contracted behind in a straight line to the obtuse posterior 

 angles ; the base finely bordered ; puncturation and iiubescence very
