DiCRAXOXEl'RA PTaMJ^.A, 11. sp. 



S . Orange -TplloTe. Head short, obtusely angular, sides rounded. 1^,'jes black, 

 not prominent. Fronotum broad, about a fifth longer than tlic head, anteriorly much 

 and roundly produced, posterior margin scarcely emarginatc. Scutellum with a dis- 

 tinct black spot at the apex. Ulytra — coritim and clavus inwardly paler orange tlian 

 on their outer sides, nerves deeper orange, the inner margin of the clavus with a 

 fuscous line : membrane with a slightly fuscous tinge, nerves pale orange ; Ist cell 

 short, angular, slightly prolonged posteriorly beyond the base of the 2nd and 3rd, 

 which are of sub-equal length ; 3rd cell (between the 2nd and 3rd straight nerves) 

 narrower than the others ; 4th cell with its oblique base extending further back than 

 either of the others. Tr'iw,^* diaphanous, slightly infuscated, iridesceut ; longitudinal 

 nerves infuscated. Le(js orange ; claws of the tarsi infuscated. Abdomen black 

 above ; genitalia orange. Length, Ig line. 



A single male taken casually at Dai'ciith "Wood, on the 7th Octo- 

 ber last. 



In eizc, this comes nearest to JHofiis minimua, J. 8ahlb. (which I 

 know only by description), yet it appeared to differ so much from this 

 and all other species with which I am acquainted, that I thought it 

 best before describing it to submit it to Dr. Sahlberg, who thus writes 

 concerning it : — " A species unknown to me. It is to be distinguished 

 " from AT. minimus by the form of the head, the eyes less prominent 

 " posteriorly, the broader pronotum with its posterior margin scarcely 

 " emarginate, and the form of the genitalia, as well as by the different 

 " colour." 



TyPHLOCYBA CRATiEOI, W. sp. 



Pale whitish-yellow. Ilead obtusely pointed, the sides rounded. Pronotum 

 scarcely one-fourth longer Ihan the head, posterior margin slightly concave. Scu- 

 tellum, like the head and pronotum, spotless. Elytra shining, pale yellowish with 

 a greenish tinge, the lower margin of tlic clavus throughout narrowly and regularly 

 palo fuscous-brown ; membrane pale fuscous, with somewhat indistinct yellowish 

 nerves ; at the base of the colls on the corium a transverse row of more or less dis- 

 tinct fuscous spots. Wings diaphanous, iridescent, nerves pale. Legs palo, claws of 

 the tarsi fuscous. Abdomen whitish-yellow. Length, IJ line. 



Allied to T. (/ratiosn, Boh., but smaller, elytra yellower, narrower, 

 the fuscous stripe on the outer margin of the clavus not so broad and 

 of uniform width, and the spots on the corium next the membrane 

 rounder and less distinct. The s])ceics is unknown to. Dr. J. Sahlberg 

 and M. Lethierry.
