110 INSSCUTOR INSCITI^ M^NSTRUUS 



Further records are at hand, though not in every case 

 tested by males, as follows: Tree-holes, Jennings, Nos. 37, 

 28, 38, 288, 210, 303, 374, 393, 394; Busck, No. 102; Zetek, 

 No. 666 ; miscellaneous receptacles, "trunk of large fallen 

 tree" (Jennings, 55), "from container" (Jennings, 118), "from 

 old kettle" (Jennings, 48), "food material from some point 

 on line south of Paraiso" (Jennings, 74), "wooden box" 

 (Busck, 201), "old machinery" (Busck, 221), "pot-holes on 

 Taboga Island" (Busck, Nos. 182, 206), On two occasions 

 Jennings took the larvae from a stream (Nos. 379, 387) ; but 

 he noted that "undoubtedly" they had been emptied there from 

 some container, as a washerwoman was at work at the stream. 

 Less typical are three occurrences noted by Jennings : "Pa- 

 raiso, from cut, with Anopheles and Uranotaenia" (Nos. 30, 

 31), "Ancon Boulevard, no oil" (No. 52) and "pool" (No. 

 111). These were evidently ground pools, and while No. Ill 

 is a female and need not detain us as it may be chalcospilans 

 of normal occurrence, Nos. 30 and 52 contain males which are 

 undoubtedly argyromeris. We have therefore the occasional 

 occurrence in ground pools when these are of artificial pro- 

 duction. 



Haemagogus (Haemagogus) chalcospilans, new species. 



Head and prothoracic lobes dark violet, mesonotum green, 

 abdomen dark violet, with the usual play of colors; scales of 

 pleurae silvery white ; abdomen with lateral silvery patches, 

 conjoined toward base and forming more or less complete 

 dorsal bands posteriorly. Wing scales dark, the second mar- 

 ginal cell longer than the second posterior cell. Claws of the 

 female sinple ; palpi of the male about one-sixth the length of 

 the proboscis. 



Hypopygium. Side pieces three times as long as wide, 

 rounded at tip ; basal area swollen within, with a large mi- 

 nutely pilose area bearing very small setae from tubercular 

 bases ; a small setose rounded lobe at extreme base ; scales on 

 distal inner area of side piece crooked, enlarged on one side, 

 mixed with narrow crooked spines and at the tip a tuft of 

 curved setae ; a second tuft of smaller setae at the tip out-
