CH/ETOSPILA Westwood, Thes. Ent. Oxon., p. 137. 

 (Type C. elegans Westw.) 



" Caput quadratum antice trilobatum ; mandibulae subtrigonae apice 

 obliquo ^-dentato (pi. xxv, fig. ica) ; maxillae lobo apicali membranaceo 

 rotundato setoso, palpis maxillaribus 4-articulatis articulis primo et tertio 

 brevibus (fig. lob); mentum oblongo-ovale ; labium oblongum in medio 

 paullo constrictum apice rotundato, palpis labialibus biarticulatis articulis 

 aequalibus (fig. IDC) ; antennae S-articulatse (absque articulis annuliforme- 

 bus) articulis 2-7 longitudine fere aequalibus at sensim crassioribus, ultimo 

 majori longo-ovali (fig. rod) ; collare semiovale capite angustius ; meso- 

 noti scutum breve, scutellum magnum; pedunculus abdominalis brevis ; 

 abdomen magnum ovale ; alae amplae, setis longis marginatae, vena sub- 

 costali trientem costae vix attingente, apice ejus in fasciculum setarum 

 erectarum terminate, ramo stigmaticali minuto; pedes graciles." 



Unknown to me. Prof. Westwood further says: "The re 

 markable fascicles of short erect bristles at the junction of the 

 subcostal vein with the costa is quite peculiar, and, so far as I 

 have observed, does not occur in any other insect. The insect is 

 closely allied to Cerocephala, from which it differs in the short 

 peduncle to the abdomen and the 8-jointed antennae, these organs 

 in Cerocephala being distinctly zo-jointed, the eighth and ninth 

 being equal in size to the two preceding joints." 



The type C. elegans is figured 1. c. supra, on pi. xxv, fig. 10, 

 and was reared from Zea mays. It is undoubtedly parasitic 

 on some Coleopteron living in the corn. 



The peculiar fascicles of short erect bristles to which Prof. 

 Westwood calls especial attention is likewise at times present in 

 Cerocephala. It is a peculiar feature of Sciatheras trichotus 

 Ratz., and is very distinctly shown in his figure of this insect, 

 Ichn. der Forstins, Bd. ii, Taf. iii, fig. i. Moreover, on page 

 209 he has called especial attention to it in the following words : 

 44 Weit eigenthiimlicher und ganz einzig ist die Verzierung der 

 Fliigel-Junktur. Hier steht ein Flausch von feinen Borstchen 

 (Fig. a, schwach vergrossert und Fig. 6, jener Flausch in einer 

 etwas veranderten Richtung stark vergrossert)." 



The genus appears to me scarcely distinct from Cerocephala. 



SPALANGIA Latreille, Gen. Crust, et Ins., iv, p. 29. 



(Type S. niger Latr.) 



Head oblong or ovate, anteriorly truncate. Eyes ovate, hairy. Ocelli 

 3, in a triangle. 



Mandibles oblong, bidentate at tips. 

 Maxillary and labial palpi 2-jointed. 



Antennce elbowed, inserted at the mouth, 10- or 12-jointed, in 9 clavate 

 or subclavate, in <$ filiform, the third joint elongated.
