314 Mr. F. P. Pascoe on some new Genera of 



callosity on each side of the disk at the base ; elytra covered 

 with numerous small punctures, each elytron with two fine 

 slightly raised lines ; body beneath and legs brownish luteous. 

 Length 7 lines. 



Ipothalia. 



Antenna breves, incrassatae, serratae, art. quarto et quinto obeonicis, 



cseteris dilatatis, ultimo ovato vel triangulari. 

 Prothorax lateraliter tuberculatus. 

 TibicB anticae et intermediae spinis duabus minutis terminatae. 



Head anteriorly and mandibles moderately produced. An- 

 tennae short, gradually thickened from the third to the seventh 

 joint, the remainder, except the last, about the same size, and, 

 including the sixth and seventh, dilated, especially on one side ; 

 the second short, the third more than twice the length of the 

 two following, the last ovate or triangular, flattened on one side. 

 Prothorax rather longer than broad, stoutly tuberculate on each 

 side. Elytra rather small, a little depressed. Posterior femora 

 abruptly clavate. Anterior and intermediate tibiae terminated 

 by very short spines. 



The other characters are pretty nearly the same as are common 

 to the more normal Callichrominae ; the scutellum, however, 

 forms a nearly equilateral triangle, with its two sides a little 

 rounded, and its apex presenting a sort of prolonged appendage, 

 especially evident in /. femorata. One of my species appears to 

 be a male, the other (/. pyrrha) a female. If so, there will be 

 no difference in the antennae of the two sexes. 



Ipothalia femorata. 



I. cyanea, nitida, prothorace viridi ; femoribus, basi excepta, laete 



luteis. 



Hah, Philippine Islands. 



Rich (rather dark) blue ; prothorax green ; head very sparingly 

 punctured, a deep groove in front of each eye, terminating below 

 in the transverse groove above the clypeus ; prothorax smooth, 

 very minutely punctured ; elytra finely punctured, the punctures 

 crowded, but not coalescing; body beneath blue, meso- and 

 metathorax covered with a silvery pubescence; femora, except 

 at the base, bright luteous ; tibiae blue, tarsi tinged with blue ; 

 antennae entirely blue. Length 6 lines. 



Ipothalia pyrrha. 



I. cyanea, elytris viridescentibus, medio antennarum pedibusque 

 laete luteis. 



Hah. Pegu. 



Dark blue ; elytra dark bluish green ; head minutely and
