100 (e. wasmann s. j.) species novae insectobum 



8 — 10 quadratis, 11° ovato, latiore 10°, apice oblique truncato. 

 Prothorax et elylra densissime subtiliter punctata. Abdomen dense 

 et subtiliter punclatum, omnino immarginatum, punctis apicem 

 versus substriatis. Long. 4, 5 mm. 



Antennis brevibus, apicem versus incrassatis et compressis ad 

 genus L a m p r i n u s Kr, propius accedit baec species quam 

 reliquae species generis G o n o s o m a Americae septentrionalis. Ut 

 in genere L a m p r i n o forma illa antennarum adaptatie quaedam 

 ad vitam hic quidem termitophilam esse videlur, quae ad «typum 

 proteclivum » (Trutztypus) Cephaloplectinorum (sive Xenocephali- 

 noruni) appropinquat. 



Exemplar unicum cum larva ejusdem speciei vidi a D. Haroldo 

 Heath die 29» Decembris anni 1901 in nido G al o ter mi ti s 

 castane! Burm. piope Pacific Grove ') in Galifornia inventum, 

 cui speciem novam dedico. 



Scripsil mihi D. Heath haec de relalionibus illius speciei cum 

 termitibus: cel watched them (the beetle witii the larva) for several 

 days (in an observation-nest), but never detected them eating any 

 secretion or excretion from their hosts ; but probably they took 

 vegetable matter as they journeyed to and fro. The larva with the 

 tern)inal hairy tufi had the curious habit, when approached by a 

 termite, of turning the abdomen so that the hairs were pushed 

 into the face or against the body of the intruder, who speedily 

 beat a retreat. This larva I gave every means of escape, but it 

 invariably remained with the termites, from which I infer that it 

 is a termilophile. » 



Ex eo, quod G o n o s o m a illud cum sua larva in termitum nido 

 inventa sit, certo conhrmatur, quod species ilia sit vere, non solum 

 fortuito, termitophila. Ad larvae descriptionem haec nefanda videntur: 



Larva (fere adulta): Long. 4,5 mm. Supra brunnea, infra 

 pallide testacea, depressa, subparallela, pilis brevioribus erectis dense 



1) Fere 120 milliaria anglica versus meridiem ab urbe San Francisco. Idem 

 postea mihi transmisit specimiua Trichopseuii depressi Lee. , quae in 

 Termitis flavi pedis Koll. societate prope Staudford University iu Cali- 

 fornia legerat.
