6. Diestota sperata. 
Diestota sperata, Sharp, Trans. Ent. Soc. Lond. 1876, p. 47°. 
Hab. Guatemata, Cerro Zunil, 4000 to 5000 feet, Tamahu, Capetillo and 
Guatemala city (Champion); Panama, Bugaba (Champion).—Soutn America, Amazon 
valley 1. 
7. Diestota brevicornis. 
Rufescens, antennarum basi pedibusque testaceis, capite, antennis abdomineque ante apicem fuscis, elytris 
fusco-testaceis humeris dilutioribus; minus subtiliter pubescens, parce punctata, sat nitida; antennis 
brevibus, apicem versus incrassatis, articulis 5°-10™ transversis. 
Long. 12 millim. 
Hab. GuateMata, Zapote (Champion). 
Antenne short and rather stout, much thickened towards the extremity ; third joint 
short, shorter than second; fourth smaller than any of the others, hardly so long as 
broad; fifth to tenth short, each of them transverse and a little broader than its 
predecessor, so that the tenth joint is moderately transverse, terminal joint not large. 
Head short and broad, narrowed behind the eyes, very indistinctly punctate, rather 
shining. ‘Thorax strongly transverse, very nearly as broad as the elytra, scarcely visibly 
punctate, finely pubescent, shining, with a small transverse depression in front of the 
base in the middle. Elytra a good deal longer than the thorax, of an infuscate-yellow 
colour, with a more or less vague paler humeral spot of variable extent, finely and not 
closely punctate. Hind body with the basal segments indistinctly and rather sparingly 
punctate, the apical ones nearly impunctate. Legs clear yellow. 
A series of six individuals shows little variation. Compared with D. sperata the 
individuals of this species are seen to be considerably smaller, more sparingly punctate, 
and more shining, with considerably shorter antenne. Jam only able to get a very 
imperfect view of the hind margin of the seventh dorsal segment; but I think the 
structure in the male sex is similar to that of D. sperata. 
8. Diestota debilis. 
Parvula, angustula, subtiliter pubescens, parce subtilissime punctulata, sat nitida, rufo-testacea, abdomine 
ante apicem infuscato; antennis brevibus, apicem versus incrassatis; prothorace omnium brevissimo; 
abdomine fere impunctato. 
Long. 13 millim. 
Hab. GuaTEMALA, Capetillo, Las Mercedes 3000 feet, (Champion). 
Antenne quite short, a good deal thickened towards the apex, joints fifth to tenth 
transverse, the last of them strongly so. Head small, with small eyes, scarcely visibly 
punctate, shining. Thorax very short, with the sides and base rounded, scarcely visibly 
punctate, shining, with but slight trace of basal impression. Elytra differing but little
