Of the extreme ^.■ll'i(•ty (if forms whieli species of Carabidffi present, none is more 

 remark;di]e than that nf J/nr/i/n/i/c,/. Tlie commonest species is 3L j^hyllodes, a beetle 

 often reaeliint;' three inches in h^n^th, 

 and found in tlie forests uiion the moun- 

 tains of Ja\a, where its remarkalile form, 

 best shown by the figure, has attracted 

 the attention of the natives, iiy wiiom it 

 I'i iiaWn'X hihUolaJi an. Its antenna' and 

 leiis are black; the rest of the beetle is 

 pitch-brown, a little lighter in shade 

 upon tlic iiKU'iiins of the elytra. 'I'hese 

 beetles, as well as their larva-, are found 

 about J-'o/i/purtifi j'onn/itKri'is, a fungus 

 upon the truidcs of trees. Thi' lai-vie, 

 which exhibit no remarkalile structural 

 peculiarities, and resendile those cif ( \iri(- 

 liiis, li\-c within the fungus, feeding, it is 

 sii]i]iosed, ujiou the larwa? of otlier insects. Pu|.)ation takes place within the fungus, and 

 the form of the elytra in the pupa indicates, to a certain extent, the remarkable form of 

 the beetle that is to emerge fnun it. Lar\'al life requires from eight to nine months ; ])upal 

 life from eight to ten weeks. Tiie im.-igos are found mostly from August to November. 

 A large sub-family, the Ilarpaliiue, includes such Carabida' as have the " middle 

 coxal cavities entirely enclosed bv the stern:i, the ejiiineron not reaching the coxa; 

 head without antennal grooves beneath, ami sujiraorbital distinct set;e ; ainbulatorial 

 seta> of abdomen usually well-developed." 



The genus lldrimhis includes a large numlierof flattened usually 

 black beetles, of which it is often ilithcult to determine the species. 

 Most of them li.-ive ne.iriy S(iu:ire prothoi'ax. Of the s]iecies of this 

 genus II. calif/ i /I ('.■< II. ■< is \ cry common in the eastern Tnited States, 

 often feeding upon the pollen and seeds of the common ragweed 

 (AMhro.tia artemisiaj'iiliii). It is about an inch in 

 length. A muuber of slightly smaller sjiecies .are 

 equally common, and have similar habits to the one 

 Last mentioned. Not very different from IlarjMfiig 

 in structure ami habits .are the many species of ^1/;/-
