CRYPTOPHAGID. 579 
2. Tisiphone mexicanus, sp. n. 
Depressus, opacus, testaceus, supra subtilissime punctatus ; thorace medio linea angusta, impunctata. 
Long. 1} millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Closely allied to T. chontalenus, and distinguished by the smaller size, still more 
depressed form, smaller eyes, and the indistinct impunctate line along the middle of 
the thorax. One specimen. 
3. Tisiphone distans, sp. n. 
Sat convexus, subtiliter punctatus, ferrugineo-testaeeus ; prothorace antrorsum angustato, elytris angustiore. 
Long. 13 millim. 
Hab. GuateMAua, Carrizal in Vera Paz (Champion). 
‘This species is readily distinguished from all the others of the genus by the more 
convex elytra and the narrower thorax. The head is small, with small and very convex 
eyes. The thorax is distinctly narrower than the elytra, a good deal narrowed in front, 
the hind angles very obtuse, the punctuation extremely fine, without trace of an 
impunctate area along the middle. The punctuation of the elytra is extremely fine, 
not dense. ‘The pygidium is much deflexed. One specimen. 
This insect will probably form a distinct genus, as the more contracted thorax is 
accompanied by a greater approximation of the front coxe and a slightly different 
structure of their acetabula. It more nearly resembles the North-American 7’. palmicola 
than any other species I have seen. 
Fam. CRYPTOPHAGIDE *. 
In this work we have adopted the system of arrangement made use of in the 
Munich Catalogue of Coleoptera, so far as the sequence of families is concerned. As 
considerable changes have taken place in the views of taxonomists since that Catalogue 
was published, it is necessary to make a few remarks on certain points connected with 
Cryptophagide. In the important work in course of publication by Dr. Ganglbauer 
(‘ Die Kafer Mitteleuropa’), the family Cryptophagide is regarded as merely a division 
of Erotylide. ‘This course has long since been advocated by me, but it cannot here be 
adopted, as the Erotylide have already been treated fully in our Vol. VII. of the 
Coleoptera. The system I here adopt is not, therefore, to be considered as expressing 
my own views. In the Munich Catalogue the Biphylline are placed as a subdivision 
of Mycetophagide, but this is certainly erroneous, and renders it impossible to define 
the Mycetophagide. I therefore place the group in question in the family under 
consideration at present, a course which has already been adopted by Dr. Ganglbauer.
