Cryptops hortensis. The antennae are 17-jointed, pubescent, seta- 

 ceous, submoniliform, full as long as the head and the two following 

 segments ; the basal joints are broader than long, the apical joints 

 longer than broad. The labium is smooth beneath, slightly hairy, the 

 suture is indistinct; the jaws are like those of Lithobius. The color 

 of the body is usually ferruginous, the legs are j)aler, and the last pair 

 somewhat brighter than the body. There are 21 segments ; they in- 

 crease in length from the head to the tail, and two sections pass through 

 the disk of each. The head is flat and conical, and has a very short 

 suture in fronf, and apparently forms but one segment. The legs have 

 6 joints, the first is shorter than the second, but from the second the 



* The divisions here proposed and named appear to me scarcely entitled to rank as 

 genera, yet I could not include the species under any of the equally restricted groups 

 proposed by Serville : Agelasta very nearly approaches several of the Brazilian gene- 

 ra; Abryna and Euclea approach Cryptocranium ; Cacia is somewhat similar to Ani- 

 socerus scopiferus, a very common South-American insect ; Agnia is equally like 

 Ptychodes politus, lineatus, &c. Plocia, in general form, appears intermediate be- 

 tween Colobothea and Leptocera, yet in some characters it likewise resembles Hypsi- 

 omus cristatus ; to the last-named genus Achthophora is also allied ; and Thysanodes 

 is almost too near the New Holland species Rhytiphora porphyrea, but unfortunately 

 that genus is so restricted, that several other species all but identical with porphyrea 

 are excluded. The new names are proposed with much hesitation, and being placed 

 in parentheses, entomologists will use their own judgment either in adopting them, or 

 referring the species to the previously described genera indicated in this note. Being 

 firmly convinced that every genus must of necessity be an artificial assemblage of spe- 

 cies, I am far from ambitious of imposing generic nomenclature.
