J'liinimeiie loiitdiui. — In tins genns the front is wider than in Cabcrodes, 

 Eitliit]>('l((, or Tctnicis. 'I'lie occipital region {i.e., the occiput and cpicraniMin 

 l()g<jther) is nearly as long as the clypeus; the epicr.miuin is long, unii'orndy 

 so, foriuint;- a transverse hand as widi; at tlie middle as the v\\[\>i. The 

 epicraniuni is scpiarish ; hind ediic hnt slightly conviix ; a median central 

 depression; antenna' inserteil wide ;;part. Clypeus squarish, heinir but little 

 longei'than liroad ; the sides narrow a little anlerioi'ly, the orhits iiuich more; 

 tin; p;)sterior and anterior edges are both mutdi rounded, and the siirlace is 

 very convex, as much so as in Caberode.s. The head grows wider on (he 

 occipital region than in Eutrapchi or Cid>e.rO(l('^, and the eyes are smaller and 

 Halter, the clypeal region being wider. 



'retracis crocallala — Occipital region lai'ger than in Eutidpela and 

 Caherodes ; the epicraniuni being longer, aud- j)rojecting more In'oadly 

 between the sockets (d" the antcnuic and the eyes. Ej)icranium transversely 

 oval, somew^hat approaching that of EiitraptJa in form; both pieces moder- 

 ately convex. Aiitenn;u as wide apart as in Eiitrapda. Clypeus in form like 

 Cabcrodes. but a little less convex, though much more so tlian in Eutrapcln, 

 and a lillle more trai)ezoidal than in Cabcrodes. Mandibles and labrum as 

 usual. Maxillaj large. The whole head is smaller, and the eyes decidedly 

 smaller, than in Cabcrodes. 



Cabcrodes inetrocamparia. — The occipital region is large, but tin; occiput 

 i> smaller than in Kufrapcia, being shorter, while the epicraniuni is consider- 

 ably larger than in Eutrapela, and does not foi'm a lozenge, the hind edge 

 being very convex. Surlace very full and ctuivex, much niore so betwetni the 

 antemuv than in Eutrapela, the space between them being wider. The cly- 

 peus is subtrapezoldal, the sides narrowing a lillle anterioily, and the siit- 

 tace is very convex, much niori; so than in Clidcrodcs, rising up Hush with llu; 

 eyes; it is considerably longer than broail. Thus, Edlrapc/a is much ncMrc^r 

 to Cydimon Lellus \\\M\ Cabcrodes is; in the latter, the head grow ing widfT 

 between the oyca.
