23. Xenocerus varians sp. nov. 



,V. harhirorni (1875) valde attinis, sed olj'tris aliter signatis, ]irotliorace lireviore 

 lateribns panini rotnudato, Koi^xms feminae, art. 4" et 5" tenuioribus omiiiiio breviter 

 pilosis, art. d" et T" longioribus quatn in barbicorni. 

 Species dichromatica. 



(«) Forma prima : A', varians ab. farcifer. 



<?. Caput et thorax signatnra burhicornis : antennae art. 1° — 5° infra ))ilosae, 

 5" arcuato. Elytra his siguaturis albis signata : vitta brevissima lA mm. longa 

 sntnrali basali cum altera in utrinsijne elytri interspatio 3'" sitaantemediaua counexa, 

 hoc mode signatnram fnrcae similem formante; macula transversa antemediana ab 

 hac signatura (quaoum conjuncta) ad spatium S"" extensa, macula humerali sub- 

 luniformi callnm humeralem supra ct jiostice ciugente limbum lateralem nou 

 attiiigeute in interspatio 5° in dcntem dilatata ; fascia transversa postmediaua 

 4 mm. ante apicem sita, fere recta, sed inter strias l"'" et 4""' antrorsnm parum, 

 dilatata, sutnram fere attingente, ad striam 9^'" abbreviata ; macula anteapicali 

 margini apicali suliparallela. Pygidium utriuque albo maculatum, ajncc albo 

 marginatum. Scutellum album. 



Prosternum vitta laterali supra coxam iuterrupta lata siguatum ; processus 

 prostemalis cum coxis albns. Mesosternnm ntrinque album, processus intra- 

 coxalis albns. Metasternum utrinque duabus vittis siguatum, una in episterno sita, 

 altera miuus bene expressa inter coxas secundi et tertii ])aris : coxis jiosticis pro 

 maxima parte albis. Abdomen utriuque duabus seriebus macularum albarum 

 notatum: maculis ejusdem segmenti ad limbum apicalem conjunctis, in segmento 

 1° fasciam latam transversam formautibus. Femora (macula mediana laterali 

 excepta), tarsornmqne articulornm 1', 3'', 4' dimidinm basale albo-pubescentia ; 

 tibiae albescentes. 



? . A mare dififert elytris macula antemediana longitudinali (hand transversa) 

 inter strias 7"" et 0"" sita 2^ mm. longa, atque macula parva marginali aut libera 

 aut cum ilia macula connexa, notatis: pygidio utrincjue vitta abbreviata signato. 

 (b) Forma secunda : A', rariaiis al). interruptus. 



(?. Vitta snturali nulla; maculas autemcdiauis dorsali et laterali baud con- 

 junctis, fascia postmediana transversa subinterrnpta. 



?. Vitta suturali ut in forma («), sed cum macula dorsali hand conjuncta. 

 Ilab. Both forms found on Leite, August lb',)6 (J. Whitehead). 

 There can be no doubt that we have here to do only with individual variation; 

 the two forms agree in every respect except in the pattern of the basal half of the 

 elytra. However, as the forms have a rather different aspect, I have thought it 

 best to treat them under different aberrational names, in order to prevent them being 

 described one day as different species. 



24. Xenocerus fasciatus sp. nov. 



S Praecedenlis structura, sed elytris fascia antemediana hand interrupta 

 ntrinque striam decimam attingente signatis distiugueudtis. 



Ilab. Samar, June— July 1896; 2 <?<?. 



This and the preceding Xenocerus arc most ])robably only geograjiiiicul forms 

 of the same species. In fasciatus the humeral lialf-ring does not reacdi laterally 

 beyond stripe 7; the short basal macula on the suture is as in carians, but instead
