A Crypta (genus Coleopteroruni) ct fJ.op(f)Tj figura. 



I had for some time regarded the insect on wliich the present genus is founded 

 as a true Fsammoecus {= Crypta, Steph. a.d. 1830), to which both in its habits 

 and outline it is very closely allied. A more careful examination, however, of its 

 oral organs and feet has subsequently con'vinced me that it is impossible to asso- 

 ciate it ^ith that group, as usually defined (and of which the Anthicusbipimctatus 

 of Fabricius is supposed to be the typo), however much it may resemble some of 

 the meml)crs of it externally, — since it is wanting in many of the most essential 

 structural characteristics on which it is made to depend. Thus, the enormously 

 developed secm-iform joint \\'\.t\\ which the maxillary palpi of Psamiiioecus are 

 terminated is here narrow and fusiform, and even acuminated towards its apex ; 

 whilst the labial ones have their ultimate articulation immenselv swollen, and 

 more abruptly hatchet-shaped than is there the case. Its mandibles also, which 

 are bidiMitate at their extremity, and have a small additional subapical tooth 

 within, recede from those of Fsainmoecm, and coincide almost entirely with the 

 modification which obtains in Dendrophagxs. Then, the mentum likewise is of a 

 very different form, being deeply emarginated anteriorly, instead of produced; 

 whilst, lastly, its tarsi (instead of being quadriarticulate) arc pentamerous in the 

 females (the minute fourtli joint being concealed between the greatly enlarged 

 lobes of the third), and heteromerous (unless indeed my observations deceive me) 

 in the males. U])on the whole, therefore, I should consider Cryptamorpha as an
