TELEPHOIUD/E. — MALTHINUS. 305 



among oaks and other high trees, but it is somewhat rare in the 

 latter. " Glanville's Wootton." — J. C. Dale, Esq. 



Genus CCXL. — Malthinus, Latreille. 



Antenna; elongate, slender, filiform, rather distant at their origin ; the second 

 and third joints shortest ; the remainder elongate, cylindric ; the basal one 

 subclavate. Palpi with the terminal joint ovate, acuminated at the apex, and 

 nearly subulated : head rather large, more or less attenuated posteriorly : 

 eyes more or less projecting: thorax subtransverse : elytra slender, generally 

 shorter than the abdomen : wings large, exposed at the apex : legs rather long, 

 slender. 



Malthinus differs from Telephorus by several very obvious 

 characters : the terminal joint of the palpi is ovate, acuminated, not 

 securiform, the elytra are generally very much abbreviated, the wings 

 large, exposed at the apex, the insects generally of minute bulk, 

 linear-elongate, &c, and they usually prefer trees for their habita- 

 tion ; — there are either many species, or they are very prone to 

 vary. 



A. With the head rhomboidal; the eyes very prominent. 

 Sp. 1. flaveolus. Flavus, vertice nigro, thorace fusco-maculato, elytris Juscis, 



apice rotundatis sulphureis, ahdomine vix brevioribus. (Long. Corp. 2g lin.) 

 Ca.flaveola. PaykuL— Ma. flavus. Steph. Catal. 133. No. 1351. 



Yellow : the head posteriorly black, much punctate : the thorax dull flavescent, 

 with two large fuscous spots on the disc, frequently united : the elytra fuscous, 

 with the apex rounded, and sulphur-yellow: legs dusky-yellow: antennae 

 yellow, with the apex dusky. 



Known from the following by its spotted thorax, brighter colour, and larger 

 size.

apice rotundatis sulphureis. (Long. corp. 2 — 2^ lin.) 

 Ca. immunis. Marsham. — Ma. immunis. Steph. Catal. 133. No. 1352.
