XANTHOLINUS. 485 
A series of about twenty examples was procured, exhibiting a little variation in the 
size and number of the punctures of the thoracic series and the distinctness of the 
brassy tint of the upper surface. 
26. Xantholinus guatemalenus. 
Fuscus ; elytris fusco-testaceis, capite nigro ; supra leviter seneo-tinctus, nitidus; capite fortiter minus crebre 
punctato, medio levigato ; prothorace seriebus dorsalibus 3-punctatis ; elytris thoracis longitudine, parce 
subobsolete punctatis; antennis pedibusque testaceis. 
Long. 8 millim. 
Hab. Guaremata, San Gerdénimo (Champion). 
Antenne stout ; second and third joints elongate, the latter the longer. Head convex, 
oblong, slightly narrowed in front, its punctures large and distant. Thorax with only 
three punctures in the dorsal series; they are large and placed on the posterior two 
thirds; there are also four other large punctures on each side. 
Though similar to X. wneotinctus this species can be readily distinguished by the 
thoracic punctuation; the head, too, is rather longer and narrower; only one example 
has been found. 
27. Xantholinus flagellifer. 
Rufescens, supra leviter eneo-tinctus ; capite ened, elytris infuscatis ; antennis crassis ; capite ovali, minus dense 
et fortiter punctato; prothorace seriebus dorsalibus obsoletis, tantum versus basin perstantibus ibidemque 
irregularibus ; elytris crebre fortiter punctatis. 
Long. 9 millim. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Antenne unusually stout, second and third joints rather long. Head very shining 
brassy, between the frontal grooves with an excessively minute punctuation; the disc 
impunctate, about the rounded hind angles and vertex with distant, not very coarse 
punctures. Thorax elongate, a little narrowed behind, very shining red, faintly 
tinctured with brassy, towards the base on each side of the middle with a group of 
punctures; these and two punctures near the front represent the discoidal series, and 
there are in addition a few quite irregularly placed punctures near the sides. The 
elytra are about as long as the thorax, infuscate red, more pallid at the base, a little 
tinted with brassy, rather coarsely punctate. Legs clear yellow-red. 
Three examples. 
28. Xantholinus panamensis. 
Fusco-rufus, zeneo-tinctus, nitidus ; capite ovali, gracili, sat crebre fortiter punctato ; prothorace seriebus dorsali- 
bus circiter 8-punctatis, ad basin utrinque punctis adjectis nonnullis ; elytris fortiter sat crebre punctatis, 
summa basi rufa. 
Long. 83 millim. 
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion).
